Passing Command line argument to Python program using IDLE?
提问by Saher Ahwal
I have downloaded a python file xxxxxx.py that is supposed to run on the command line by
typing: python xxxxxx.py filename1 filename2and that should take these two files as arguments.
我已经下载了一个 python 文件 xxxxxx.py，它应该通过键入在命令行上运行：python xxxxxx.py filename1 filename2并且应该将这两个文件作为参数。
I was wondering if there is a way I can use IDLE to pass in these arguments. Is there a way other than setting sys.argv?
我想知道是否有一种方法可以使用 IDLE 来传递这些参数。除了设置还有别的方法sys.argv吗？
Thanks
谢谢

You can do this from the command line with:
您可以从命令行执行此操作：
idle.py -r scriptname.py put arguments here
idle.py -r scriptname.py 把参数放在这里
You can try a different IDE like ActivePython

It depends on the content of your Python file. If it is well-written, like:
这取决于您的 Python 文件的内容。如果写得很好，比如：
#! /usr/bin/env python
def process(files):
for file in files:
# ...
if __name__ == '__main__'
# some error checking on sys.argv
process(sys.argv[1:])
sys.exit(0)
Then you could simply import the python file and run it like:
然后你可以简单地导入 python 文件并像这样运行它：
import name_of_file
# ...
name_of_file.process([file1, file2, file3])
# ...
So, it really depends on how it is written. If it isn't written well but you can edit it, I would refactor it so that it can be used as a library; otherwise, I would use the subprocess module to invoke the program.
所以，这真的取决于它是如何写的。如果写得不好但可以编辑，我会重构它，以便它可以用作库；否则，我将使用 subprocess 模块来调用该程序。
