Python : Get a complete list of external modules imported by my script and their version

In my script, I imported 5 external modules this way :

import numpy as np
import scipy.io as sio
import pandas
import IPython
from termcolor import cprint

I want to get a complete list of external modules and versions imported above, so I wrote the following script :

    def imports():
        modulesList = []
        for name, val in globals().items():
            if isinstance(val, types.ModuleType):
                modulesList.append(val.__name__)
        return modulesList

    import pip
    installed_packages = sorted([ i.key for i in pip.get_installed_distributions() ])
    modules = sorted(imports())
    for module_name in modules:
        module = sys.modules[module_name]
        if module_name.lower() in installed_packages :
            try : moduleVersion = module.__version__
            except : moduleVersion = '.'.join( map(str, module.VERSION) )
            print( "=> Imported %s version %s" % (module_name , moduleVersion) )

If I run this script, python shows :

=> Imported IPython version 6.0.0
=> Imported numpy version 1.13.1
=> Imported pandas version 0.20.2

instead of what I expect, which is the following :

=> Imported IPython version 6.0.0
=> Imported numpy version 1.13.1
=> Imported pandas version 0.20.2
=> Imported scipy version 0.19.0
=> Imported termcolor version 1.1.0

Can you help ?

So two things I determined from running your code. IPython isn't getting matched because of the line:

if module_name in installed_packages :

The installed_packages shows it as 'ipython' while you are checking for 'IPython'.

The second thing is the line:

modules = sorted(imports())

I'm not sure why but termcolor doesn't show up with

from termcolor import cprint

but does with

import termcolor

Not entirely sure what to make of that.

EDIT:

def imports():
modulesList = []
for name, val in globals().items():
    if isinstance(val, types.ModuleType):
        modulesList.append(val.__name__)
    elif isinstance(val, types.FunctionType):
        modulesList.append(sys.modules[val.__module__].__name__)
return modulesList

That should get you termcolor.
