FWIW the afaik most common symbolic math Python library sympy does that on the first page of their tutorial. I think in this space it's pretty common.

I have to admit that I still like to use the ancient

    from pylab import *

in scripts that only I will ever see. It makes it so much easier to use numpy in a "tool of thought" way. I would never do this in a library, though.

Two wrongs don't make a right. It risks significant ambiguity in longer snippets or files, and is therefore bad practice.
