Using Python packages in Unity scripts

I have bunch of functionality written in Python that I would like to use in Unity3D. I considered using UniPython or IronPython but from what I read these plugins only embed Python ,as in you can use the syntax but not python packages installed with pip, which is what my code uses.

Can anyone confirm if the available python plugins will actually allow this or if not - Is there a way I can add my python code into Unity without having to rewrite them in C# and have to look for equivalent C# libraries?

My end goal is to be able to use python functionality inside of Unity scripts, whether that would be C# scripts using Python functions (if at all possible) or moving to Python as a scripting language.

Clarification: This is not a question of syntax, I can code in both C# and Python, it's not question of not knowing either language, it's more a question of reusing available resources.
