Introduction

Python has a set of built-in methods that you can use on strings.

python

a = "Hello, World!"
print(a.upper())

python

a = "Hello, World!"
print(a.lower())

Whitespace is the space before and/or after the actual text, and very often you want to remove this space.

python

a = " Hello, World! "
print(a.strip()) # returns "Hello, World!"

python

a = "Hello, World!"
print(a.replace("H", "J"))

The split() method returns a list where the text between the specified separator becomes the list items.

python

a = "Hello, World!"
print(a.split(",")) # 
  returns ['Hello', ' World!']
