Python's str.isalpha() method returns a boolean indicating whether all characters in a string are alphabetic (a - z).

Parameters

No parameters.

Return value

A single boolean indicating whether or not all the characters in a string are alphabet letters. If the string is empty False is returned.

Examples

Basic usage

To check whether all characters in 'Sky Towner' are alphabetic:

x = 'Sky Towner'
x.isalpha()
False
False

The space character is not alphabetic, hence False is returned.

To check whether all characters in 'SkyTowner' are alphabetic:

y = 'SkyTowner'
y.isalpha()
True

To check whether all characters in 'SkyTowner!' are alphabetic:

z = 'SkyTowner!'
z.isalpha()
False

The ! character is not alphabetic, hence False is returned.

Empty string

If the string is empty, False is returned:

a = ''
a.isalpha()
False
