.upper & .lower

This might be a dumb questions but what do .upper and .lower mean and what are they called? I feel like that was never covered.

upper is short for "Uppercase" and lower is short for "Lowercase".

They are what are called methods which are essentially functions that belong to a class. More specifically they are methods that belong to strings. Which means that you can use them on a string to perform some action on it.

The upper method takes a string and converts it to uppercase and lower converts it to lowercase. Example:

example = "Hello World!"

print(example.upper())
# Prints: "HELLO WORLD!"

print(example.lower())
# Prints: "hello world!"
