#### Python Modules ####
-A module is a file containing Python definitions and statements.
-A module can define functions, classes and variables.
-A module can also include runnable code.
-Grouping related code into a module makes the code easier to understand and use.
## Two Ways use Module ##
1-The import statement.
2-The from import Statement.
## The dir() function
