编辑：回到这里：它与python3的子进程一样具有魅力，如果您在linux上，则有一个名为subprocess32的python2反向移植，可以很好地完成工作
def cmdlineCall(name, args):
child = pexpect.spawn(name, args)
# Wait for the end of the output
child.expect(pexpect.EOF)
out = child.before # we get all the data before the EOF (stderr and stdout)
child.close() # that will set the return code for us
# signalstatus and existstatus read as the same (for my purpose only)
if child.exitstatus is None:
returncode = child.signalstatus
else:
returncode=child.exitstatus
return (out,returncode)
PS：慢一点（因为它会生成伪tty）
