Question

in py_script.py:

import os
import sys

l = len(sys.argv) 
if  l == 1:
    print 'no args'
else:
    if l > 1: 
        print 'first arg is %s'%sys.argv[1]
    if l > 2:
        print 'second arg is %s'%sys.argv[2]

now going command-line, on my winXP platform:

d:\path\py_script.py 1 2

yields

first arg is 1
second arg is 2

yet on my Win7 platform I get

no args

If I do

d:\path\python py_script.py 1 2

I get

first arg is 1
second arg is 2

How can I make my Win7 environment act as expected ?

some details:
win7 is 64bit.
py2.6.6 on win7, py 2.6.4 on winXP.

Answer 1

Based on jtp’s answer.
Well I messed up with the registry a bit.

This was what I think are the steps:

1. doing

   assoc .py=Python.File

2. through win explorer pick a .py file, right click -> x64 -> open with > browse to c:\Python26\python.exe choose the ‘always open with this..’ box.
   this in effect changes immediately the reg value

   HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts.py\UserChoice
   to
   Python.File

3. set HKEY_CLASSES_ROOT\Python.File\shell\Open\Command to
   “C:\Python26\python.exe” “%1” %2 %3 %4 %5 %6 %7 %8 %9

note: from previous experience i’m sure things are expected to mess up with mixed versions.
uninstalling/re-installing shall be the way to go. BTW, I didn’t want to go through that becuase with all the packages including ones I built from source it would be a mess.
