问题
I need to capture the stdout of a process I execute via subprocess into a string to then put it inside a TextCtrl of a wx application I'm creating. How do I do that?
EDIT: I'd also like to know how to determine when a process terminates
回答1:
From the subprocess documentation:
from subprocess import *
output = Popen(["mycmd", "myarg"], stdout=PIPE).communicate()[0]

Take a look at the subprocess module.
http://docs.python.org/library/subprocess.html
It allows you to do a lot of the same input and output redirection that you can do in the shell.
If you're trying to redirect the stdout of the currently executing script, that's just a matter of getting a hold of the correct file handle. Off the top of my head, stdin is 0, stdout is 1, and stderr is 2, but double check. I could be wrong on that point.
