Setup a private space for you and your coworkers to ask questions and share information. I've tried to solve it many ways, but couldn't get to the pint. I want to make exc. If I type "hello" the output to be in numbers lined like in alphabet. This does the same thing, but is more readable. Make sure you can understand what is going on here before you try to understand my first answer.
Everything here is pretty standard, simple Python.
The one thing to note is the ord function. It gives you a mapping to the numerical representation of any character. The inverse function of ord is called chr. If you test for yourself, the ordinal of a is 97 the third link I posted above will show the complete ASCII character set. Each lower case letter is in the range 26 characters. The rest of the initial solution I posted is just some Python trickery you can learn called list comprehension. But, I wouldn't focus on that as much as I would focus on learning to solve the problem in any language, where ord is your friend.
I hope this helps. If you are going to use this conversion a lot, consider calculating once and putting the results in a dictionary:. The first, without commas and what you have in your question, is a one element list with a 26 element string. The second is a 26 element list each a single character in length. It becomes apparent that it takes an additional step to turn the individual characters of char1 into an iterable.
Something like this. Here's something I use to convert excel column letters to numbers so a limit of 3 letters but it's pretty easy to extend this out if you need more. Probably not the best way but it works for what I need it for. If the goal is to transform only the letters abcd XYZ , I would use a function:.
Because the parameter d receives a value as a default argument, the calculus of this value is performed only once, at the moment when the definition of the function is executed to produce the function object. So, the function can then be used without this value to be calculated again, even if the function is appealed three thousand times. The case of upper letters has been treated during the construction of the default argument. Please note that I have gone only up to 2 levels as I had to convert divisions in a class to A, B, C etc.
Here is my solution for a problem where you want to convert all the letters in a string with position of those letters in English alphabet and return a string of those nos.

Those lists don't have commas. What do you actually want for output, please show example? In your pastebin code maketrans takes a string of letters to letters mapping like 'abcd', ''. The Khmer alphabet for Cambodian is the longest, with 74 letters. Alphabets are usually associated with a standard ordering of letters. This makes them useful for purposes of collation , specifically by allowing words to be sorted in alphabetical order.
It also means that their letters can be used as an alternative method of "numbering" ordered items, in such contexts as numbered lists and number placements. The history of the alphabet started in ancient Egypt. Egyptian writing had a set of some 24 hieroglyphs that are called uniliterals,  to represent syllables that begin with a single consonant of their language, plus a vowel or no vowel to be supplied by the native speaker.
These glyphs were used as pronunciation guides for logograms , to write grammatical inflections, and, later, to transcribe loan words and foreign names. In the Middle Bronze Age , an apparently "alphabetic" system known as the Proto-Sinaitic script appears in Egyptian turquoise mines in the Sinai peninsula dated to circa the 15th century BC, apparently left by Canaanite workers. In , John and Deborah Darnell discovered an even earlier version of this first alphabet at Wadi el-Hol dated to circa BC and showing evidence of having been adapted from specific forms of Egyptian hieroglyphs that could be dated to circa BC, strongly suggesting that the first alphabet had been developed about that time.

An alphabetic cuneiform script with 30 signs including three that indicate the following vowel was invented in Ugarit before the 15th century BC. This script was not used after the destruction of Ugarit. The Proto-Sinaitic script eventually developed into the Phoenician alphabet , which is conventionally called "Proto-Canaanite" before ca.
This script is the parent script of all western alphabets. By the tenth century, two other forms can be distinguished, namely Canaanite and Aramaic. The Aramaic gave rise to the Hebrew script. Vowelless alphabets are called abjads , currently exemplified in scripts including Arabic , Hebrew , and Syriac. The omission of vowels was not always a satisfactory solution and some "weak" consonants are sometimes used to indicate the vowel quality of a syllable matres lectionis.
These letters have a dual function since they are also used as pure consonants. The Proto-Sinaitic or Proto-Canaanite script and the Ugaritic script were the first scripts with a limited number of signs, in contrast to the other widely used writing systems at the time, Cuneiform , Egyptian hieroglyphs , and Linear B. The Phoenician script was probably the first phonemic script   and it contained only about two dozen distinct letters, making it a script simple enough for common traders to learn.
Another advantage of Phoenician was that it could be used to write down many different languages, since it recorded words phonemically. The script was spread by the Phoenicians across the Mediterranean. It was the first alphabet in which vowels have independent letter forms separate from those of consonants. The Greeks chose letters representing sounds that did not exist in Greek to represent vowels. Vowels are significant in the Greek language, and the syllabical Linear B script that was used by the Mycenaean Greeks from the 16th century BC had 87 symbols, including 5 vowels.
In its early years, there were many variants of the Greek alphabet, a situation that caused many different alphabets to evolve from it. The Greek alphabet , in its Euboean form , was carried over by Greek colonists to the Italian peninsula, where it gave rise to a variety of alphabets used to write the Italic languages. One of these became the Latin alphabet , which was spread across Europe as the Romans expanded their empire. Even after the fall of the Roman state, the alphabet survived in intellectual and religious works.
It eventually became used for the descendant languages of Latin the Romance languages and then for most of the other languages of Europe.

Other alphabets only use a subset of the Latin alphabet, such as Hawaiian, and Italian , which uses the letters j, k, x, y and w only in foreign words. Another notable script is Elder Futhark , which is believed to have evolved out of one of the Old Italic alphabets. Elder Futhark gave rise to a variety of alphabets known collectively as the Runic alphabets. Its usage is mostly restricted to engravings on stone and jewelry, although inscriptions have also been found on bone and wood. These alphabets have since been replaced with the Latin alphabet, except for decorative usage for which the runes remained in use until the 20th century.
How many letters are there in the Arabic alphabet?
The Old Hungarian script is a contemporary writing system of the Hungarians. It was in use during the entire history of Hungary, albeit not as an official writing system. From the 19th century it once again became more and more popular. The Glagolitic alphabet was the initial script of the liturgical language Old Church Slavonic and became, together with the Greek uncial script, the basis of the Cyrillic script. Cyrillic is one of the most widely used modern alphabetic scripts, and is notable for its use in Slavic languages and also for other languages within the former Soviet Union.
The Glagolitic alphabet is believed to have been created by Saints Cyril and Methodius , while the Cyrillic alphabet was invented by Clement of Ohrid , who was their disciple. They feature many letters that appear to have been borrowed from or influenced by the Greek alphabet and the Hebrew alphabet. The longest European alphabet is the Latin-derived Slovak alphabet which has 46 letters. Beyond the logographic Chinese writing , many phonetic scripts are in existence in Asia. The Arabic alphabet , Hebrew alphabet , Syriac alphabet , and other abjads of the Middle East are developments of the Aramaic alphabet.
Most alphabetic scripts of India and Eastern Asia are descended from the Brahmi script , which is often believed to be a descendant of Aramaic. In Korea , the Hangul alphabet was created by Sejong the Great. Zhuyin sometimes called Bopomofo is a semi-syllabary used to phonetically transcribe Mandarin Chinese in the Republic of China. After the later establishment of the People's Republic of China and its adoption of Hanyu Pinyin , the use of Zhuyin today is limited, but it is still widely used in Taiwan where the Republic of China still governs. Zhuyin developed out of a form of Chinese shorthand based on Chinese characters in the early s and has elements of both an alphabet and a syllabary.
Like an alphabet the phonemes of syllable initials are represented by individual symbols, but like a syllabary the phonemes of the syllable finals are not; rather, each possible final excluding the medial glide is represented by its own symbol. While Zhuyin is not used as a mainstream writing system, it is still often used in ways similar to a romanization system—that is, for aiding in pronunciation and as an input method for Chinese characters on computers and cellphones.
European alphabets, especially Latin and Cyrillic, have been adapted for many languages of Asia. Arabic is also widely used, sometimes as an abjad as with Urdu and Persian and sometimes as a complete alphabet as with Kurdish and Uyghur. Egyptian hieroglyphs 32 c.

In the wider sense, an alphabet is a script that is segmental at the phoneme level—that is, it has separate glyphs for individual sounds and not for larger units such as syllables or words.
In the narrower sense, some scholars distinguish "true" alphabets from two other types of segmental script, abjads and abugidas. These three differ from each other in the way they treat vowels: abjads have letters for consonants and leave most vowels unexpressed; abugidas are also consonant-based, but indicate vowels with diacritics to or a systematic graphic modification of the consonants. In alphabets in the narrow sense, on the other hand, consonants and vowels are written as independent letters. Examples of present-day abjads are the Arabic and Hebrew scripts ; true alphabets include Latin , Cyrillic, and Korean hangul ; and abugidas are used to write Tigrinya , Amharic , Hindi , and Thai.
The Canadian Aboriginal syllabics are also an abugida rather than a syllabary as their name would imply, since each glyph stands for a consonant that is modified by rotation to represent the following vowel. In a true syllabary, each consonant-vowel combination would be represented by a separate glyph. All three types may be augmented with syllabic glyphs. These are the only time vowels are indicated. The boundaries between the three types of segmental scripts are not always clear-cut.
For example, Sorani Kurdish is written in the Arabic script , which is normally an abjad. However, in Kurdish, writing the vowels is mandatory, and full letters are used, so the script is a true alphabet. Other languages may use a Semitic abjad with mandatory vowel diacritics, effectively making them abugidas.
On the other hand, the Phagspa script of the Mongol Empire was based closely on the Tibetan abugida , but all vowel marks were written after the preceding consonant rather than as diacritic marks. Although short a was not written, as in the Indic abugidas, one could argue that the linear arrangement made this a true alphabet. Conversely, the vowel marks of the Tigrinya abugida and the Amharic abugida ironically, the original source of the term "abugida" have been so completely assimilated into their consonants that the modifications are no longer systematic and have to be learned as a syllabary rather than as a segmental script.
Even more extreme, the Pahlavi abjad eventually became logographic. See below. Thus the primary classification of alphabets reflects how they treat vowels. For tonal languages , further classification can be based on their treatment of tone, though names do not yet exist to distinguish the various types. Some alphabets disregard tone entirely, especially when it does not carry a heavy functional load, as in Somali and many other languages of Africa and the Americas.
Such scripts are to tone what abjads are to vowels. Most commonly, tones are indicated with diacritics, the way vowels are treated in abugidas. This is the case for Vietnamese a true alphabet and Thai an abugida. In Thai, tone is determined primarily by the choice of consonant, with diacritics for disambiguation.

In the Pollard script , an abugida, vowels are indicated by diacritics, but the placement of the diacritic relative to the consonant is modified to indicate the tone. More rarely, a script may have separate letters for tones, as is the case for Hmong and Zhuang. For most of these scripts, regardless of whether letters or diacritics are used, the most common tone is not marked, just as the most common vowel is not marked in Indic abugidas; in Zhuyin not only is one of the tones unmarked, but there is a diacritic to indicate lack of tone, like the virama of Indic.
The number of letters in an alphabet can be quite small. The Book Pahlavi script, an abjad, had only twelve letters at one point, and may have had even fewer later on. Today the Rotokas alphabet has only twelve letters.
However, Hawaiian Braille has only 13 letters. While Rotokas has a small alphabet because it has few phonemes to represent just eleven , Book Pahlavi was small because many letters had been conflated —that is, the graphic distinctions had been lost over time, and diacritics were not developed to compensate for this as they were in Arabic , another script that lost many of its distinct letter shapes.
For example, a comma-shaped letter represented g , d , y , k , or j.
However, such apparent simplifications can perversely make a script more complicated. In later Pahlavi papyri , up to half of the remaining graphic distinctions of these twelve letters were lost, and the script could no longer be read as a sequence of letters at all, but instead each word had to be learned as a whole—that is, they had become logograms as in Egyptian Demotic.
The largest segmental script is probably an abugida, Devanagari. The Hindi alphabet must represent both Sanskrit and modern vocabulary, and so has been expanded to 58 with the khutma letters letters with a dot added to represent sounds from Persian and English. Thai has a total of 59 symbols, consisting of 44 consonants, 13 vowels and 2 syllabics, not including 4 diacritics for tone marks and one for vowel length.
The largest known abjad is Sindhi , with 51 letters. The largest alphabets in the narrow sense include Kabardian and Abkhaz for Cyrillic , with 58 and 56 letters, respectively, and Slovak for the Latin script , with With 33 letters, it is the largest true alphabet where each letter is graphically independent. The Georgian alphabet is much closer to Greek than the other Caucasian alphabets. The letter order parallels the Greek, with the consonants without a Greek equivalent organized at the end of the alphabet.
The origins of the alphabet are still unknown. Syllabaries typically contain 50 to glyphs, and the glyphs of logographic systems typically number from the many hundreds into the thousands. Thus a simple count of the number of distinct symbols is an important clue to the nature of an unknown script.
It was created in year A. The Armenian script's directionality is horizontal left-to-right, like the Latin and Greek alphabets. Alphabets often come to be associated with a standard ordering of their letters, which can then be used for purposes of collation —namely for the listing of words and other items in what is called alphabetical order.
In French, these are not considered to be additional letters for the purposes of collation. It is unknown whether the earliest alphabets had a defined sequence. Some alphabets today, such as the Hanuno'o script , are learned one letter at a time, in no particular order, and are not used for collation where a definite order is required. However, a dozen Ugaritic tablets from the fourteenth century BC preserve the alphabet in two sequences.
Runic used an unrelated Futhark sequence, which was later simplified. Arabic uses its own sequence, although Arabic retains the traditional abjadi order for numbering. The Brahmic family of alphabets used in India use a unique order based on phonology : The letters are arranged according to how and where they are produced in the mouth.
This organization is used in Southeast Asia, Tibet, Korean hangul , and even Japanese kana , which is not an alphabet. The Phoenician letter names, in which each letter was associated with a word that begins with that sound acrophony , continue to be used to varying degrees in Samaritan , Aramaic , Syriac , Hebrew , Greek and Arabic.
The names were abandoned in Latin , which instead referred to the letters by adding a vowel usually e before or after the consonant; the two exceptions were Y and Z , which were borrowed from the Greek alphabet rather than Etruscan, and were known as Y Graeca "Greek Y" pronounced I Graeca "Greek I" and zeta from Greek —this discrepancy was inherited by many European languages, as in the term zed for Z in all forms of English other than American English.
The French names from which the English names are derived preserve the qualities of the English vowels from before the Great Vowel Shift. In Cyrillic originally the letters were given names based on Slavic words; this was later abandoned as well in favor of a system similar to that used in Latin. Letters of Armenian alphabet also have distinct letter names. When an alphabet is adopted or developed to represent a given language, an orthography generally comes into being, providing rules for the spelling of words in that language.
