How to Install a Python Module?
A module helps you to arrange your Python code logically. The code is easier to understand and use when it is organized into modules. You can bind and reference a module, which is a Python object with arbitrarily named attributes.
A module is simply a file containing Python code. Functions, groups, and variables can all be described in a module. Runnable code can also be used in a module. A module can be imported by multiple programs for their application, hence a single code can be used by multiple programs to get done with their functionalities faster and reliably.

Manual installation of Python packages
The majority of Python packages are now designed to work with pip. If you have a kit that isn’t compatible, you’ll have to install it manually.
Install the kit by downloading it and then extracting it to a local directory. If the kit has its own set of installation instructions, obey them, if the package is not present there then use the following command to install the package using the command manually:
python <FILE_NAME>.py install
