What is the best way of listing all imported modules in python?

问题

Usually, after doing numerical SciPy/NumPy calculations in the interactive mode for several hours, a bunch of modules become to be loaded.

Are there any good ways to see the list of imported modules from the interactive python command line?

Thanks!

回答1:

Use sys.modules:

import sys
print '\n'.join(sys.modules)

回答2:

Use Pip

pip freeze

Using:

pip freeze > requirements.txt 

will save all the modelues in a text file.
