Introduction to Modules

A module is a python file containing objects like docstrings, variables, constants, classes, objects, statements, functions. 

A module is created as a python (.py) file containing a collection of function definitions.

To use a module, we need to import the module . Once we import a module, we can directly use all the functions of that module. 

There are two forms of import statements:  

1. import<module name>  
2. from<module> import<object> 

To call a function of a module, the function name should be preceded with the name of the module with a dot(.) as a separator. 

The syntax is as shown below: 

• modulename.functionname( )
