我们的脚本需要做的第一件事就是获取命令行参数的值。当我搜索“python command line arguments”时,出现的第一个结果是关于sys.argv的,所以我们来试试这个方法…… “初学者”的方法 sys.argv 是个列表,包含用户在运行脚本时输入的所有参数(包括脚本名自身)。
It is not possible to start two modules using two -m arguments. This is because the command line arguments after -m are all given to the named module as sys.argv. This is not described explicitly in the documentation but you can try it out experimentally. Create two python files a.py ...
