PIP and Modules in Python

 In Python, a module is a file containing Python definitions and statements. Modules can be imported into other Python files in order to use the code contained within them. For example, if you have a module called "mymodule.py" that defines a function called "myfunction()", you can import that module into another file and use the function like this:

import mymodule 
 mymodule.myfunction()

pip is a package installer for Python. It allows you to install and manage third-party Python libraries and modules, which can be imported and used in your Python code. To install a package using pip, you can use the command pip install package_name. For example, to install the popular Python library "numpy", you would use the command pip install numpy. To upgrade a package, use pip install --upgrade package_name. To uninstall a package use pip uninstall package_name.
It is also possible to use pip to install packages from a specific version, for example pip install package_name==1.0.0.
