how to import file passed as command line argument in python

Question

I tried to import a file var.py to openfile.py. var is passed as an argument to openfile. I am unable to figure out how to import it by reading the name from command line.

var = sys.argv[1]
importlib.import_module(var, package=None)

I tried the above code but it gave the below error

Traceback (most recent call last):
  File "true.py", line 7, in <module>
    importlib.import_module(var, package=None)
NameError: name 'importlib' is not defined

Shuldn't you import importlib itself?

you are missing importlib module.

Thats why you are getting NameError: name 'importlib' is not defined

do import importlib

Note:

If imporlib is not installed, you can install it using easy_install/pip on *nix:

easy_install importlib

This version of the answer is much better than the original one that simply recommended installing with easy_install importlib ;-)

You have to import the importlib module first:

import importlib
....
importlib.import_module(...)
