How can I check if character in a string is a letter? (Python)

I know about islower and isupper, but can you check whether or not that character is a letter? For Example:

>>> s = 'abcdefg'
>>> s2 = '123abcd'
>>> s3 = 'abcDEFG'
>>> s[0].islower()
True

>>> s2[0].islower()
False

>>> s3[0].islower()
True

Is there any way to just ask if it is a character besides doing .islower() or .isupper()?

Solution

  • You can use str.isalpha().

    For example:

    s = 'a123b'

for char in s:
    print(char, char.isalpha())

    Output:

    a True
1 False
2 False
3 False
b True
