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

Question

I know about islower and isupper  but can you check whether or not that character is a letter  For Example    gt  gt  gt  s    abcdefg   gt  gt  gt  s2    123abcd   gt  gt  gt  s3    abcDEFG   gt  gt  gt  s 0  islower   True   gt  gt  gt  s2 0  islower   False   gt  gt  gt  s3 0  islower   True   Is there any way to just ask if it is a character besides doing  islower   or  isupper
