Remove Whitespace
Whitespace is the space before and/or after the actual text, and very often you want to remove this space.
Example
The strip()
method removes any whitespace from the beginning or the end:
a = " Hello, World! "
print(a.strip()) # returns "Hello, World!"

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

method splits the string into substrings if it finds instances of the separator:
a = "Hello, World!"
print(a.split(",")) #
returns ['Hello', ' World!']
