Question

I’m really confused, I wrote this code and I’m trying to pull in some functions I defined, but I’m not passing the right information somewhere. Does anyone have any tips or pointers? I’m not sure how to describe what my problem is, but the error is:

Traceback (most recent call last):
  File "./test3.py", line 54, in <module>
    bar()
  File "./test3.py", line 26, in disconnectvpn
    child.sendcontrol('c')
NameError: global name 'child' is not defined

My fixed program code looks like this:

def foo():
    child = pexpect.spawn ('./script.sh -arg1')
    child.expect ('(?i)user input:')
    child.sendline ('response')
    return child
def bar(child):
    child.sendcontrol('c')

a = foo()

bar(a)

Answer 1

1. first of all you need to return child object from connectvpn() and
   capture it
2. You need to pass it in disconnectvpn() before using it
