Python string isalpha() method example

In this source code example, we will demonstrate how to use the Python string isalpha() method to check if all characters in a string are alphabetic.

Use the Python string isalpha() method to check if all characters in a string are alphabetic.

The alphabetic characters are characters defined as letters in the Unicode character database.
Python string isalpha() method exampleThe following example uses the isalpha() method to check if a string contains alphabetic characters:

name = 'Rock'
print(name.isalpha())

Output:

True
It returned True because the string 'Rock' contains only alphabetic characters.

The following example returns False because the string 'John Cena' contains a space:

name = 'John Cena'
print(name.isalpha())

Output:

False
The following example returns False because the string contains a number:
name = 'John Cena 123'
print(name.isalpha())

Output:

False
The following example returns False because the string is empty:
name = ''
print(name.isalpha())

Output:

False
