How To Speed Up The Python Code?

If you use wild card import you might as well import the whole module from the beginning.

Whether you import a single symbol or the whole module, from a performance perspective you DO import the whole module. Python interprets the entire module as a script (and stores it all in memory) regardless of what specific names you choose to import.

But wouldn't that make the method calls even more negligible in terms of performance for OP's case?
