How do I import another python file provided as command-line-argument?

Question

This is what a.py looks

import sys


def test_import(another_python_file):
    import another_python_file as b
    b.run_me()

if __name__ == '__main__':
    print sys.argv
    test_import(sys.argv[1].strip())

this is what b.py looks

def run_me():
    print 'I am script b'

When I run, I get

$ python a.py b.py
['a.py', 'b.py']
Traceback (most recent call last):
  File "a.py", line 10, in <module>
    test_import(sys.argv[1].strip())
  File "a.py", line 5, in test_import
    import another_python_file as b
ImportError: No module named another_python_file

What I need? I would expect it to import b.py and print I am script b

What am I missing?

a.py:

import os
import sys


def test_import(another_python_file):
    b = __import__(another_python_file)
    b.run_me()

if __name__ == '__main__':
    print sys.argv
    test_import(sys.argv[1].strip('.py'))

b.py
def run_me():
    print 'I am script b'

$ python a.py b.py
['a.py', 'b.py']
I am script b

I was able to do that referring to http://www.diveintopython.net/functional_programming/dynamic_import.html

If you don't need flexibility, you can simply use __import__('module_name'). If you need advanced features like cache control, module searching or reloading, use the imp module.
