(Haven't seen a truly naive implementation posted yet so...)
The following implementation is "naive", because it does not cover the edge cases, and will break in other cases. It is very simple to understand, and can convey a programming message.
def naive_inverse(x):
return 1/x
It will:
- Break on x=0
- Do a bad job when passed an integer
You could make it more "mature" by adding these features.
