如何以跨平台方式从另一个Python脚本运行一个Python脚本? [英] How to run a Python script from another Python script in the cross-platform way?

问题描述

这是问题所在...

我正在为Blender编写非常小的插件， 我有10个python脚本，它们通过使用命令行来解析不同的文件格式，并且我有一个Main Python脚本，可以使用适当的命令来运行所有其他脚本...

例如，"Main.py"包括:

txt2cfg.py -inFile -outFile ...
ma2lxo.py -inFile -outFile ...

Blender已经包含Python，因此我可以从Blender中运行"Main.py"，但是我需要它可以与PC和MAC一起使用，并且不需要Python安装，因此我不能使用:

• execfile('txt2cfg.py -inFile -outFile')
• os.system('ma2lxo.py -inFile -outFile')
• 甚至导入子流程

因为他们需要安装Python才能运行* .py文件.

对不起，语言

谢谢

解决方案

例如，"Main.py"包括:

txt2cfg.py -inFile -outFile ... ma2lxo.py -inFile -outFile ...

两件事.

1. 每个其他脚本都需要main()函数和"main-import开关".请参见 http://docs.python.org/tutorial/modules. html#executing-modules-as-scripts 以获得有关其外观的提示.

2. 导入并执行其他脚本.

   import txt2cfg
   import ma2lxo
   txt2cfg.main( inFile, outFile )
   ma2lxo.main( inFile, outFile )
   

这是做事的最简单方法.

Here is the problem...

I'm writing very small plugin for Blender, I have 10 python scripts, they parsing different file formats by using command-line, and I have a Main Python script to run all other scripts with proper commands...

for example, "Main.py" include:

txt2cfg.py -inFile -outFile...
ma2lxo.py -inFile -outFile...

Blender already include Python, so I can run "Main.py" from Blender, But I need it to work with both PC and MAC, and also doesn't require Python installation, so I can't use:

• execfile(' txt2cfg.py -inFile -outFile ')
• os.system(' ma2lxo.py -inFile -outFile ')
• or even import subprocess

because they required Python installation in order to run *.py files.

Sorry for language

Thanks

解决方案

for example, "Main.py" include:

txt2cfg.py -inFile -outFile... ma2lxo.py -inFile -outFile...

Two things.

1. Each other script needs a main() function and a "main-import switch". See http://docs.python.org/tutorial/modules.html#executing-modules-as-scripts for hints on how this must look.

2. Import and execute the other scripts.

   import txt2cfg
   import ma2lxo
   txt2cfg.main( inFile, outFile )
   ma2lxo.main( inFile, outFile )
   

This is the simplest way to do things.
