Python Programming | String Testing Methods

To get to know the type of characters in a string there are several inbuilt methods in python. Here are the list of methods:

• isalpha()
• returns True if there are only alphabets in the string else it returns False
• isdigit()
• returns True if there are only numbers in the string else it returns False
• isalnum()
• returns True if there are both numbers and characters in the string else it returns False
• isupper()
• returns True if all the characters in the string are upper case letters else it returns False
• islower()
• returns True if all the characters in the string are lower case letters else it returns False
• isTitle()
• returns True if first letter in the string starts with upper case else it returns False

The output of these methods is True or False.

Example:

For the below code, output is False as there are both numbers and characters and not just characters.

string = "Way2Know"

string.alpha()
