So I know about islower and isupper, but i can't seem to find out if you can check whether or not that character is a letter?
s = 'abcdefg'
s2 = '123abcd'
s3 = 'abcDEFG'
s.islower() = True
You can use
isalpha(), see the docs at http://docs.python.org/2/library/stdtypes.html
>>> s = "a123b" >>> for i in s: ... print i, i.isalpha() ... a True 1 False 2 False 3 False b True
