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

Question

I know what us islower and isupper, but how can we check whether a character in a string is a letter?Example:

>>> s = 'abcdefg'

>>> s2 = '123abcd'

>>> s3 = 'abcDEFG'

>>> s[0].islower()

True

>>> s2[0].islower()

False

>>> s3[0].islower()

True

Is there any way to check without using .islower() or .isupper()?

Answer 1

You can use a function, str.isalpha()

Example:

s = 'a123b'

for char in s:

    print(char, char.isalpha())

Output:

a  True

1  False

2  False

3  False

b  True
