Python 3的命令行

Question

I have 1 python 3 script. I need to use another script via command line. What function should i use? I mean something like that:

res = execute('C:\python32\python Z:\home\192.168.0.15\www\start.pyw start=1 module=server > Z:\home\192.168.0.15\www\test.html')

Answer 1

Check out the Process Management section of the os module

http://docs.python.org/3/library/os.html#module-os

os.popen will work well if you are interested in i/o with the process

Answer 2

Use the subprocess module. That gives you the most flexibility.

Answer 3

This is a python program you want to start. It would be better to import the module, run the method you want and write the output to a file.

However, this would be how you can do it via shell execution:

from subprocess import *
command_stdout = Popen(['C:\python32\python', 'Z:\home\192.168.0.15\www\start.pyw', 'start=1', 'module=server'], stdout=PIPE).communicate()[0]
res = command_stdout.decode("utf-8")
fd = open('Z:\home\192.168.0.15\www\test.html',"w")
fd.write(res)
