import os
os.popen('python helloworld.py') # Just run the program
os.popen('python helloworld.py').read() # Also gets you the stdout
预先使用：subprocess
import subprocess subprocess.call(['python','helloworld.py']) # Just run the program subprocess.check_output(['python','helloworld.py']) # Also gets you the stdout
