This is such a fallacy. It's very easy to make code that compiles but
crashes. Compilers just compile code, they do not give it a magic "This
program is well written" certificate. Use pychecker, be happy. or better
yet, test your code.

how is that different from some C code casting inappropriately deep in
the bowels of your app? In python, you at least get a useful exception,
in C you just get a nasty segfault and fun with the debugger.
I strongly suggest you take a look at this interview with GvR:
here's a snippet: "That attitude sounds like the classic thing I've
always heard from strong-typing proponents. The one thing that troubles
me is that all the focus is on the strong typing, as if once your
program is type correct, it has no bugs left. Strong typing catches many
bugs, but it also makes you focus too much on getting the types right
and not enough on getting the rest of the program correct."
