How to check if a character in a string is a letter in Python?
You can use the isalpha() method from string class. It checks if a string consists only of alphabets. You can also use it to check if a character is an alphabet or not. For example, if you want to check if char at 5th index is letter or not,
>>> s = "Hello people" >>> s.isalpha() True
You can also check whole strings, if they are alphabetic or not. For example,
>>> s = "Hello people" >>> s.isalpha() False >>> "Hello".isalpha() True
