函数中的pexpect派生

Question

当我将pexpect.spawn放入一个函数中时，它似乎失败了。在下面的示例中，我希望它同时接触'/tmp/no.txt‘和'/tmp/yes.txt’。它只涉及/tmp/yes.txt。我已经尝试了“import pexpect”的所有明显位置。它不会抛出错误，只是不会运行。谢谢你的建议！

import pexpect
def fun():
    import pexpect
    fail = pexpect.spawn('touch /tmp/no.txt')

fun()
succeed = pexpect.spawn('touch /tmp/yes.txt')

$ ls /tmp/*.txt
/tmp/yes.txt
$

您需要等待命令运行：

import pexpect
def fun():
    #import pexpect you've already imported pexpect you don't need to import it again 
    fail = pexpect.spawn('touch /tmp/no.txt')
    fail.wait()

fun()
succeed = pexpect.spawn('touch /tmp/yes.txt')
succeed.wait()
