refactor: Replaced lambda expressions with def functions

[Sai-Suraj-27]

PR Description

I see that, at few places in the codebase, a lambda expression is being used instead of a def. I found all the places where this is happening using the ruff tool, and replaced all of those lambda expressions with a def function.

Seems like there are some lint failures that are happening, can you fix those?

I'm not fully sure if we should be replacing all lambda functions by def (espectially the ones that are simple like lambda x: isinstance(x, bool)), what do you think @KareemMAX? Thanks for creating the PR @Sai-Suraj-27 😄

@KareemMAX, The lint is failing because the docformatter and pydocstyle linters are conflicting about closing of Multi-line docstring quotes should be on a separate line or on the same line.
Edit: These are fixed with this PR (#27761)

I don't think it will hurt, the functions will have equivalent AST after all. Unless you prefer lambdas from a readability/writability point of view
