Should we include inbuilt libraries in the requirements.txt file !?

In Python, requirements.txt file is a type of file that usually stores information about all the libraries, modules, and packages in itself that are used while developing a particular project.

It also stores all files and packages on which that project is dependent or requires to run.

When you try to install inbuilt libraries like math, os, sys, etc following error message occurs -

ERROR: Could not find a version that satisfies the requirement math (from -r requirements.txt (line 7)) (from versions: none)
ERROR: No matching distribution found for math (from -r requirements.txt (line 7))

Any modules that are part of Python’s standard library such as math, os, sys, etc need not be listed in your requirements.txt file.

Any third party libraries that you include within your project using pip install ______ should be added.

You can find a list of standard modules included within core Python (built-in functions) in this link.

You can also enter the following command within a Python interpreter session to see them listed in your terminal.

>>> help('modules')

Hope you found it helpful !
