Python-运行外部脚本 [英] Python - run external script

问题描述

有人知道我是否有一个脚本one.py，该脚本的编写方式如下:

Does someone know if I have a script one.py which is written the following way:

if __name__ == '__main__':
    # Do something

我想从另一个脚本中调用该main函数.我该怎么办?

And I want to call that main function from another script. How should I do that?

我想可能是(假设这是launcher.py)

I guess it would be something like (let's say this is launcher.py)

# 'one' stands for import from `one.py` module
import one

if __name__ == '__main__':
    one.main()

唯一的问题是我不能用这种方式呼叫main().

应如何完成?

推荐答案

with file('a.py','rU') as f:
  co=compile(f.read(),'foobar','exec')
  exec co in {'__name__':'__main__'}
