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.

If the pip is not installed then refer to the article:

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
