“Pure paradigm” programming languages are really just toys for research and experimentation, IMO. I remember taking various courses on these sorts of things and, for example, the OOP prof would say “one of the cool things about pure OOP is that there are no loops or if statements. Now, here’s how you go about faking a loop or if statement using pure OOP, because it turns out you really need that to accomplish anything.”

In the real world you’ll want to use whatever works best, which often means a language that contains a bunch of features from different paradigms merged together. Ideally in a rational and well-structured manner, but given how much usage Python gets that’s clearly not a fundamental requirement.
