How to resolve ImportError: no module named tarfile

Question

I am not able to use tarfile module in my python script.

When i run the script i am getting error "ImportError: no module named tarfile"

if i remove "import tarfile" then its failing at tarfile.open; Error says--NameError: tarfile

def make_tarfile(output_filename, source_dir):
    tar = tarfile.open(output_filename, "w:gz")
    #tar.add(source_dir, arcname=os.path.basename(source_dir))
    tar.add(source_dir)
    tar.close()

The same thing happening for subprocess module also. I have verified the modules and they exists. Note that all the modules are working in python console or at command line

Python Version#2.6

I need 50 reputation to comment, so I'll leave an answer instead:

Could you add the following line to your script:

print sys.version

Just to make absolutely sure the Python version running the script is the same as the one you use as an interpreter. Like people said, maybe an environment variable is overwritten somewhere, causing a wrong version of Python to run the script.
