Check if a Character is Alphabet or Not
To check if given character is an alphabet or not in Python, call the string function isalpha(), and pass the character as argument. String.isalpha() returns a boolean value of True if the given character is an alphabet, or False otherwise.
Program
In this example, we write a function to read a character from user, and check if the character is alphabet or not.
Python Program
ch = input('Enter a character : ')
if ch.isalpha():
print(ch, 'is an alphabet.')
else:
print(ch, 'is not an alphabet.')
CopyOutput #1
Enter a character : b
b is an alphabet.
Output #2
Enter a character : 5
5 is not an alphabet.
Summary
In this Python Examples tutorial, we learned how to check if given character is an alphabet or not.
