Time taken by an import in Python

Question

I want to know how much time an import takes for both built-in as well as user defined modules.

Answer 1

Starting from Python3.7 releaese, new -X importtime option is available. To measure import time, just simply execute your script with that option, e.g. python -X importtime my_script.py.
