Alphabet range in Python

>>> import string>>> string.ascii_lowercase'abcdefghijklmnopqrstuvwxyz'

If you really need a list:

>>> list(string.ascii_lowercase)['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']

And to do it with range

>>> list(map(chr, range(97, 123))) #or list(map(chr, 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']

Other helpful string module features:

>>> help(string) # on Python 3....DATA    ascii_letters = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'    ascii_lowercase = 'abcdefghijklmnopqrstuvwxyz'    ascii_uppercase = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'    digits = '0123456789'    hexdigits = '0123456789abcdefABCDEF'    octdigits = '01234567'    printable = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~ \t\n\r\x0b\x0c'    punctuation = '!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~'    whitespace = ' \t\n\r\x0b\x0c'

[chr(i) for i in range(ord('a'),ord('z')+1)]

In Python 2.7 and 3 you can use this:

import stringstring.ascii_lowercase'abcdefghijklmnopqrstuvwxyz'string.ascii_uppercase'ABCDEFGHIJKLMNOPQRSTUVWXYZ'

As @Zaz says:string.lowercase is deprecated and no longer works in Python 3 but string.ascii_lowercase works in both
