pexpect在函数中生成

Question

当我把它放在一个函数中时，

pexpect.spawn似乎失败了。在下面的示例中，我希望它触及'/tmp/no.txt'和'/tmp/yes.txt'。它只触及/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，只是不运行。谢谢你的任何建议！

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()
