Python Isalpha String Method
In this tutorial we will explore the Python isalpha string method. The isalpha string method gives us the ability to check a string object to see if it consists of just alphabetic characters. If the string object contains letters A thru Z then Python will return True and if the string object contains any other character or symbol we will be returned a boolean of False. So if your string contains a space it will return False.

Python Isalpha String Method Syntax
'String'.isalpha()

'String' - If this string object contains just alphabetic characters we will be returned True and this string object contains anything other than alphabetic character then we are returned a False boolean.
Examples of the Python Isalpha String Method
Example 1:
'abcdef'.isalpha()
True

Example 2:
'This is a string'.isalpha()
False

Example 3:
a = 'Python'
True

Example 4:
b = 'Python3'
False
Examples Explained

Example 1:

'abcdef'.isalpha()- In this example, we create a string object that contains only alphabetic characters and then we call the isalpha string method on our string object.

True- We are returned True because our string object only contains alphabetic characters and no other numbers or symbols.

Example 2:

'This is a string'.isalpha()- In this example, we create a string object that contains alphabetic characters and spaces then we call the isalpha string method on our string object.

False- We are returned False because object contains spaces.
Example 3:

a = 'Python'- In this example, we create a string object that contains all alphabetic characters and assign 'a' variable to represent the string object.

True- We are returned True since our string object only contains alphabetic characters.
Example 4:

b = 'Python3'- In this example, we create a string object that contains alphabetic and numeric characters and then we assign 'b' to represent the string object.

False - We are returned False because our string object contains a number.

How do I test if an input variable .isalpha ? when I try to do so, It says true even if I put a number in since I am forced to put quotes around my variable which I think is making it a string but when I try to leave it in with no quotes, I get an error

Hi, Can you tell me how to remove all non-alph characters from a string except for spaces? Thanks!
