In this post, we learned how to convert a string to uppercase or lowercase, check if a string is uppercase or lowercase, capitalize the first letter of a string, swap the case of a string, and convert a string to title case in Python.This tutorial will help you to understand the different ways of converting all characters of a string to Uppercase in Python.
Let's convert the string we defined above to title case: string = "hello world" To convert a string to title case in Python, you can use the title() method.
