1. Recursion: a simple example

The simplest example of recursion is that of a single recursive function, that is a function that calls itself:

def recursive():
    if not completed_task():
        ...
        recursive()  # the same function is called ...

Let’s consider a real program for Reeborg to execute.

Try this!

Select Home 1 and have Reeborg do the following:

def go_home():
    if not at_goal():
        move()
        go_home()

# now do it!
go_home()

Once you have tried the above and tried to understood it, go to the next lesson where we will review it and consider a slightly trickier example.
