Python String istitle() Method

Python String istitle() Method is used to verify the input string title condition, i.e., it tests and returns True if the only first character of each word is uppercase, and all other characters of each word are in lowercase.

The syntax of the method is: str.istitle()

Key Points :

• Return Type: Boolean i.e. True or False
• Parametric Values: There are no istitle() function parameters.
• The istitle() function does not take into consideration symbols and numbers in a specified string.
• Those strings having the first letter in uppercase and the rest in lowercase for all the words in it are said to be in title cased. Therefore, if a string is in the titlecase, this function returns the true returns false otherwise.

Return Value from istitle()

The istitle() method returns:

• True if the string is a titlecased string.
• False if the string is not a titlecased string or an empty string.

str = "The Best Learning Resource for Online Education";
