Add Missing Docstrings and inline comments to pytest/src/_pytest/main.py (Lines 245-490)

[LClarky]

I noticed that several functions in the file pytest/src/_pytest/main.py, specifically between lines 245 and 490, are missing docstrings and inline comments. I propose adding Sphinx-compatible docstrings to all functions in the file pytest/src/_pytest/main.py between lines 245-490. Each docstring should:

• Provide a brief overview of the function's purpose.
  

• Detail the parameters, their types, and expected values.
  

• Describe the return type and any possible return values.
  

• Document any exceptions the function might raise.
  

• inline comments should add 
  

I am open to submitting a pull request for this issue.

Specifically, we have added Sphinx-compatible docstrings to all functions in the file between lines 245-490, as requested. These docstrings include:

A brief overview of each function's purpose.

Detailed information on parameters, their types, and expected values.

Descriptions of the return type and possible return values.

Documentation of exceptions that might be raised.

Additionally, we added inline comments where necessary to improve code readability.
