Lately, I've been writing functions like this:
def f(a, b):
assert a in [1, 2, 3]
assert b in [4, 5, 6]
The point is that I'm checking the type and the values of the
parameters.
I'm curious how this does or doesn't fit into python's duck-typing
philosophy.
I find that when I detect invalid parameters overtly, I spend less time
debugging.
Are other people doing things like this? Any related commentary is
welcome.
