Python Script does not take sys.argv in Windows

Question

I have two computers with Windows, and I just found that on one of them, if I ran python code directly, like:

test_args.py input1 input2

Python will not recognized the input I gave, but this works:

python test_args.py input1 input2

I tried the code:

import sys

print 'Number of arguments:', len(sys.argv), 'arguments.'
print 'Argument List:', str(sys.argv)

And the first way(test_args.py) returns:

Number of arguments: 1 arguments.
Argument List: ['D:\Test\args\test_args.py']

While the sceond way (python test_args.py input1 input2) returns:

Number of arguments: 3 arguments.
Argument List: ['D:\Test\args\test_args.py', 'input1', 'input2']

Any idea on what this could happen? This issue only happens in one of my computers, both have same version of Windows.

Thanks!

SOLVED:

I search in regedit keyword "python" and found two keys missing %* after "C:Python27python.exe" "%1":

ComputerHKEY_CLASSES_ROOTApplicationspython.exe

ComputerHKEY_CLASSES_ROOTpy_auto_fileshellopencommand

And .py is associated with py_auto_file even though I tried assoc .py Python.File

Changing the two keys fixed this issue, thanks!

Answer 1

Check what is the association of *.py files on these two computers. The script may be executed by different Python interpreters.
