How to check if a python module has been imported?

Question

How do I check if I imported a module somewhere in the code?

 if not has_imported(\"somemodule\"):
     print(\'you have not imported somemodule\')
         


        

Answer 1

use sys.modules to test if a module has been imported (I'm using unicodedata as an example):

>>> import sys
>>> 'unicodedata' in sys.modules
False
>>> import unicodedata
>>> 'unicodedata' in sys.modules
True
