Yes, it can be very useful, and with Python, you sacrifice that.

Everything must be tested anyway, and even that may not be enough.
Recently, I was guilty of an atrocious buffer overflow in C. It wasn't
caught by the compiler or testing -- during the test run, the stack
happened to contain a series of zeros.

What you don't yet appreciate is how Python adds to program quality.
With its concise, high-level constructs, you end up expressing more with
far less code and far less boilerplate. Your code is far easier to get
right, and you can put together more complicated solutions that are
still robust.
