How to change a string into uppercase?

In Python, you can use the built-in upper() method to change a string to uppercase. Here's an example:

Change a string into uppercase in Python

original_string = "hello world"
upper_string = original_string.upper()
print(upper_string)

This will output:

HELLO WORLD

You can also call the upper() method directly on the str class. While this works, using the instance method s.upper() is the standard and more readable Pythonic approach.

Change a string into uppercase in Python using str.upper

original_string = "hello world"
upper_string = str.upper(original_string)
print(upper_string)

This will also output:
