Python: How To Generate a List Of Letters In The Alphabet

 Method 1
# First we need to figure out the ASCII code of the alphabet letters
# using the ord() function. 

>>> ord('a')
97
>>> ord('z')
122

# Get ASCII code for uppercase alphabet letters
>>> ord('A')
65
>>> ord('Z')
90

# Create alphabet list of lowercase letters
alphabet = []
for letter in range(97,123):
    alphabet.append(chr(letter))

>>> alphabet
['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']

# Create alphabet list of uppercase letters
alphabet = []
for letter in range(65, 91):
    alphabet.append(chr(letter))

>>> alphabet
['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']
　　

# Use map to create lowercase alphabet
alphabet = map(chr, range(97, 123))
>>> alphabet
['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']

# Use map to create uppercase alphabet
alphabet = map(chr, range(65, 91))
>>> alphabet
['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']
　　
method 2
string.ascii_letters
The concatenation of the ascii_lowercase and ascii_uppercase constants described below. This value is not locale-dependent.

string.ascii_lowercase
The lowercase letters 'abcdefghijklmnopqrstuvwxyz'. This value is not locale-dependent and will not change.

string.ascii_uppercase
The uppercase letters 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'. This value is not locale-dependent and will not change
