从python脚本执行cmd.exe命令

Question

I have a python script callee.py which is in a certain directory and that directory is part of the Windows PATH environment variable. In the Windows command prompt cmd.exe I can simply execute it as

> callee.py arg1 arg2

Now, I have another python script caller.py in another directory. To execute the first script I would like to use the subprocess module like

subprocess.Popen("callee.py arg1 arg2")

but this does not work, because it does not get that it should actually call python.exe callee.py ... . Furthermore,

subprocess.Popen("python.exe callee.py arg1 arg2")

does not work, because it does not find callee.py .

Is there something like subprocess.Popen which accepts the very same kind of commands that the Windows command prompt cmd.exe does?

Answer 1

Is callee.py executable? Or, why don't you give the full path?

subprocess.Popen("python.exe c:\full_path\to\callee.py arg1 arg2")

Too late, don't consider this answer.

Answer 2

它像这样工作

subprocess.Popen("cmd.exe /c callee.py arg1 arg2")
