The line:
int integer = real_number;
will produce a warning. (or an error if you are smart enough to
compile with -Werror)

But, if you know that the real number will be small enough and you
don't mind getting the floor of the float, you may wish to ignore the
error. Like mr McKinnon said, c will allow you to do wrong things.

Depending on what you are doing, the babysitting of python, may or may
not be a problem.

One thing I would like to know (not knowing python that well), is when
you make an error in python, when will the exception be thrown? At the
start of run-time, or when the guilty code is encountered? And what if
that code is in a codebranch that gets executed 0.0005% of the time?
