Windows无法将参数传递给python脚本 [英] Windows fails to pass the args to a python script

问题描述

在py_script.py中：

  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] 
  

现在正在使用命令行，在我的winXP平台上：

  d：\path\py_script.py 1 2 
  

产生

  first arg is 1 
 second arg is 2 
  

然而在我的Win7平台上， / p>

 没有args 
  

$ b b

如果我这样做

  d：\path\python py_script.py 1 2 
  

我得到

 arg is 1 
 second arg is 2 
  

如何让我的Win7环境？

一些细节：

win7是64位。

py2.6.6在win7上，py 2.6.4在winXP上。

解决方案

基于jtp的回答。

好​​了，我搞砸了注册表。 >

这是我认为的步骤：

1. assoc .py = Python.File




2. 通过win explorer选择一个.py文件， x64 - >打开与>浏览到c：\Python26\python.exe选择总是打开这个..框。
   这实际上会立即改变reg值

   
   
   

   HKEY_CURRENT_USER\软件\Microsoft\Windows \CurrentVersion\Explorer\FileExts.py\ UserChoice
   到
   Python.File
   



3. 将HKEY_CLASSES_ROOT\Python.File\shell\Open\Command设置为
   C：\Python26\python.exe％1％2％3％4％5％6％7％8％9

注意：从以前的经验，我敢肯定的事情预计混乱的混合版本。
卸载/重新安装应该是要走的路。 BTW，我不想经历，因为所有的包，包括我从源码构建它将是一团糟。

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.

解决方案

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.
