In this article we will learn about the Python keywords. First we will see a list of Python Keywords followed by the description of each keyword.

None – Special constant in Python that represents nothing or a null value

 

and – Logical and operator

 

as – Used to create an alias while importing a module

 

assert – Assert is used to create assertions which are used for debugging

 

break – Used inside loops to alter its behaviour

 

class – Used to define a new user-defined class

 

continue – Used inside loops to alter its behaviour

 

def – Used to define a used-defined function

 

del – Used to delete the reference to an object
