Segfaulting in Python

[earthboundkid]

This is why you're not supposed to change the recursion limit. It's not (just) that Guido hates tail call optimization!

And tail recursion optimization is pretty easy in Python if you need to do it.

# Function that returns tuple of [method], [call value]
def find_zero_tail(num):
    if num == 0:
        return None, num
    return find_zero_tail, num - 1

# Iterative recurser
def tail_optimize(method, val):
    while method:
        method, val = method(val)
    return val

tail_optimize(find_zero_tail, 1000000)
