If this is your feeling. I don't think Python will be a good language
for you.
My opinion is that Python paradigm is heavily depending on dynamic
type checking.
If you try to constrain Python to static type checking you will lose
almost every benefits of the language.
So you'd probably better to look for another language that feet better
with your requirements.

But are you really sure you need static type checking?
Take a look at pyunit and you will discover that it's really easy to
write unitests in Python.
