使用参数导入 python 脚本 [英] Import python script with arguments

问题描述

我有脚本:

moving1.py:

def move():
    print("walk!")

moving2.py:

def move():
    print("run!")

和ma​​n.py，可以接受通过参数参数moving1或moving2脚本来执行.

And man.py, that can accept by argument parameter moving1 or moving2 script to act.

ma​​n.py:

import sys

if len(sys.argv) <= 1:
    exit("Too less arguments calling script")

__import__(sys.argv[1])
moving = sys.modules[sys.argv[1]]

def move():
    moving.move()

现在我有了 testman.py 脚本，它必须测试 man.py 执行的所有变体:

Now I have testman.py script, that have to test all variants of man.py execution:

testman.py

import man #and somehow add here as argument "moving1"
man.move()

import man #and somehow add here as argument "moving2"
man.move()

存在很多类似的问题，但它们并不完全符合我的要求.如何向导入的脚本添加参数?问题是不检查

There exist a lot of similar questions, but they don't do exactly what I want. How can I add arguments to imported scripts? Problem is not to check

if __name__ = "__main__":

在那里，问题是使用我想要的参数完全导入脚本.可能吗?

there, problem is to import script exactly with parameters I want. Is it possible?

推荐答案

你应该把你的参数处理代码和你的导入代码分开:

You should separate your argument handling code and your import code:

ma​​n.py

import sys

def move():
    moving.move()

def setup(module):
    global moving
    moving = __import__(module)

if __name__ == "__main__":
    if len(sys.argv) <= 1:
        exit("Too less arguments calling script")

    setup(sys.argv[1])

testman.py

import man
man.setup(<name>)
man.move()

然而，这似乎是实现您正在尝试做的事情的一种非常奇怪的方式.或许你可以澄清一下你的目标?

However, this seems like a very odd way of acheiving what you are trying do do. Perhaps you could clarify your goals?
