# Make a list of the Alphabet in Python

To make a list of the alphabet:

1. Use the string.ascii_lowercase attribute to get a string of the letters in the alphabet.
2. Use the list() class to convert the string to a list.
3. The list will contain all of the letters in the alphabet.

import string # ✅ Get a list of the lowercase letters in the alphabet lower = string.ascii_lowercase list_of_lowercase_letters = list(lower) # 👇️ ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'] print(list_of_lowercase_letters) # ------------------------------------------- # ✅ Get a list of the UPPERCASE letters in the alphabet upper = string.ascii_uppercase list_of_uppercase_letters = list(upper) # 👇️ ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z'] print(list_of_uppercase_letters) 

We used the string.ascii_lowercase attribute to get a string containing the letters from a to z .

Copied! 
import string lower = string.ascii_lowercase print(lower) # 👉️ abcdefghijklmnopqrstuvwxyz 

You can use the list() class to convert the string of characters to a list containing the letters in the alphabet.

Copied! 
import string lower = string.ascii_lowercase list_of_lowercase_letters = list(lower) # 👇️ ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'] print(list_of_lowercase_letters) 

If you need to get a list of the uppercase letters, use the ascii_uppercase attribute instead.

Copied! 
import string upper = string.ascii_uppercase list_of_uppercase_letters = list(upper) # 👇️ ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z'] print(list_of_uppercase_letters) 

# Reversing the list of letters

You can use list slicing if you need to reverse the list of letters.

Copied! 
import string lower = string.ascii_lowercase list_of_lowercase_letters = list(lower)[::-1] # 👇️ ['z', 'y', 'x', 'w', 'v', 'u', 't', 's', 'r', 'q', 'p', 'o', 'n', 'm', 'l', 'k', 'j', 'i', 'h', 'g', 'f', 'e', 'd', 'c', 'b', 'a'] print(list_of_lowercase_letters) 

# Iterating over the list of letters

You can use a for loop if you need to iterate over the range of letters.

Copied! 
import string lower = string.ascii_lowercase list_of_lowercase_letters = list(lower) for letter in list_of_lowercase_letters: print(letter) # 👉️ a b c d . x y z 

If you need access to the index of the current iteration, use the enumerate() function.

Copied! 
import string lower = string.ascii_lowercase list_of_lowercase_letters = list(lower) for index, letter in enumerate(list_of_lowercase_letters): print(index, letter) # 👉️ 0 a, 1 b, 2 c . 

You can also use a list comprehension to make a list of the alphabet.

# Make a list of the Alphabet using a list comprehension

This is a three-step process:

1. Use the ord() function to get the Unicode code points of the characters a and z .
2. Use a list comprehension to iterate over the range.
3. Use the chr() function to get each letter.

Copied! 
list_of_lowercase_letters = [ chr(i) for i in range(ord('a'), ord('z') + 1) ] # 👇️ ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'] print(list_of_lowercase_letters) list_of_uppercase_letters = [ chr(i) for i in range(ord('A'), ord('Z') + 1) ] # 👇️ ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z'] print(list_of_uppercase_letters) 

The ord function takes a string that represents 1 Unicode character and returns an integer representing the Unicode code point of the given character.

Copied! 
print(ord('a')) # 👉️ 97 print(ord('b')) # 👉️ 98 

The chr function is the inverse of ord() .

Copied! 
print(chr(97)) # 👉️ 'a' print(chr(98)) # 👉️ 'b' 

It takes an integer that represents a Unicode code point and returns the corresponding character.

We used the range() class to get a range that we can iterate over and used a list comprehension to iterate over the range.

List comprehensions are used to perform some operation for every element or select a subset of elements that meet a condition.

# Getting a slice of the list of letters

You can use list slicing if you need to get a slice of the list of letters.

Copied! 
letters = [chr(i) for i in range(ord('a'), ord('z') + 1)] # 👇️ ['a', 'b', 'c', 'd', 'e', 'f', 'g'] print(letters[:letters.index('g') + 1]) 

The syntax for list slicing is my_list[start:stop:step] .

The start index is inclusive and the stop index is exclusive (up to, but not including).

Python indexes are zero-based, so the first item in a list has an index of 0 , and the last item has an index of -1 or len(my_list) — 1 .

We didn’t specify a start index, so the list slice starts at index 0 .

# Print the Nth letter of the alphabet in Python

You can also use the string module if you need to print the Nth letter of the alphabet.

Copied! 
import string print(string.ascii_lowercase[2]) # 👉️ c print(string.ascii_uppercase[2]) # 👉️ C print(string.ascii_lowercase[3]) # 👉️ d print(string.ascii_uppercase[3]) # 👉️ D 

The string module gives us access to strings containing the letters of the alphabet.

Copied! 
import string # abcdefghijklmnopqrstuvwxyz print(string.ascii_lowercase) # ABCDEFGHIJKLMNOPQRSTUVWXYZ print(string.ascii_uppercase) # abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ print(string.ascii_letters) 

The ascii_lowercase and ascii_uppercase attributes return strings containing the lowercase and uppercase ASCII letters.

To print the Nth letter, access the string at a specific index and pass the result to the print() function.

Copied! 
import string print(string.ascii_lowercase[2]) # 👉️ c print(string.ascii_uppercase[2]) # 👉️ C print(string.ascii_lowercase[3]) # 👉️ d print(string.ascii_uppercase[3]) # 👉️ D 

Python indexes are zero-based, so the first character in a string has an index of 0 , and the last character has an index of -1 or len(my_str) — 1 .

If you consider the second letter to be b , subtract 1 from the index when accessing the string.

Copied! 
import string print(string.ascii_lowercase[2 - 1]) # 👉️ b print(string.ascii_uppercase[2 - 1]) # 👉️ B print(string.ascii_lowercase[3 - 1]) # 👉️ c print(string.ascii_uppercase[3 - 1]) # 👉️ C 

Alternatively, you can use the chr() and ord() functions.

# Print the Nth letter of the alphabet using chr()

This is a four-step process:

1. Use the ord() function to get the Unicode code point of the letter a .
2. Add N to the Unicode code point of a .
3. Use the chr() function to get the corresponding character.
4. Use the print() function to print the result.

Copied! 
second = chr(ord('a') + 2) print(second) # 👉️ c second = chr(ord('A') + 2) print(second) # 👉️ C third = chr(ord('a') + 3) print(third) # 👉️ d third = chr(ord('A') + 3) print(third) # 👉️ D 

The ord function takes a string that represents 1 Unicode character and returns an integer representing the Unicode code point of the given character.

Copied! 
print(ord('a')) # 👉️ 97 print(ord('b')) # 👉️ 98 

The chr function is the inverse of ord() .

Copied! 
print(chr(97)) # 👉️ 'a' print(chr(98)) # 👉️ 'b' 

It takes an integer that represents a Unicode code point and returns the corresponding character.

We added N to the Unicode code point of the letter and passed the result to the chr() function to get the corresponding character.

Which approach you pick is a matter of personal preference. I’d use the string module as I find it more direct and easier to read.

List the Alphabet in Python

1. Use Utils From Module string to List the Alphabet in Python
2. Use range() to List the Alphabet in Python

This tutorial shows you how to list the alphabet by the range in Python.

In this tutorial, we want to store the English alphabet’s 26 lowercase characters in a Python list. The quickest way to solve this problem is by making use of the ASCII values of each character and using pre-existing functions in Python.

Use Utils From Module string to List the Alphabet in Python

The Python module string is readily available and contains pre-defined constant values that we can use for this problem. The constant string.ascii_lowercase contains all 26 lowercase characters in string format.

If you perform print(string.ascii_lowercase) , it will result in the following output:

'abcdefghijklmnopqrstuvwxyz' 

Therefore, we can use this constant and convert it into a list of characters to produce a list of the alphabet.

import string def listAlphabet():  return list(string.ascii_lowercase) print(listAlphabet()) 

['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'] 

If you prefer the alphabet list to be in uppercase, then you should use string.ascii_uppercase and reuse the code above and will produce the same output, but in uppercase format.

Use range() to List the Alphabet in Python

range() is a function that outputs a series of numbers. You can specify when the function starts and stops with the first and second arguments.

range() and map()

map() is a function that accepts two arguments: the second argument of the function is an iterable or a collection; the first argument is a function to iterate over and handle the second argument.

We’re going to use these two methods to generate a list of the alphabet using the lowercase letters’ ASCII values and map them with the function chr() , which converts integers into their ASCII counterpart.
