子进程等待脚本完成

Question

I'm calling the subprocess (expect script to run some command) and need to wait until it is finished to start another function, but with this I think it only wait until shell command is finihed, and not the expect script. Is it possible to wait for the whole process to finish?

 p111 = subprocess.Popen('gnome-terminal -e "perl /tmp/expect',shell=True)  
    os.waitpid(p111.pid,0)
    smo_final()

Answer 1

Use

https://docs.python.org/2/library/subprocess.html#subprocess.Popen.wait

  p11 = subprocess.Popen('gnome-terminal -e "perl /tmp/expect',shell=False)  
  p11.wait()

Answer 2

Use pexpect, a python expect implementation

import pexpect
...
child = pexpect.spawn(cmd) # the command you want to run
child.expect(str_expect) # the string you expect 
child.sendline(str_response) # the string with which you'd like to respond 
child.wait() # wait for the child to exit
...
# the rest of your code here
