Stopping a parent function from a nested function?

[wallgraffiti]

Here's an example:

# I want to stop function parent() from function child().

def parent():
  def child():
    print('A')
    returnparent # Or something along the lines
  child()
  print('B')
parent()

Wanted output:

Output:
A

Actual output(without the returnparent):

Output:
A
B

Is there a statement or function that serves this purpose?

This is similar to this question. There is no such statement in Python but you can raise an exception. Using the solution that I posted in the other thread, you could write this to achieve the same effect

class parent(returnable):
    def main(self):
        self.child()
        print('B')

    def child(self):
        print('A')
        self.return_()
parent()
