I think it is normal to know popular libraries of a language. For python, django, drf, fastapi, pydantic or jinja are very common.
There are some people resisting type checks in python but I think fewer and fewer. I dont think people refusing to learn basic concepts and libraries are a reason to not use something.
Also, I am not a big fan of not doing something useful because we need to do a bit of learning. It seems like a variant of "we have always done it this way". Plus it is a strawman attributed to python developers, IMO.
