C has typed variables, so it's a compile-time error to try to put any
other type into that variable. Python doesn't. That flexibility comes
at the cost of error-catching. There are hybrid systems, but in
general, type declarations imply variable declarations, and that's
something that Python doesn't want. (I'm of the opinion that
declarations aren't such a bad thing; they make some aspects of
scoping easier. However, that's a design decision that Python is as
unlikely to reverse as indentation-defined blocks.)

No, it doesn't. You can find good references on the subject in various
places, but call-by-reference as implemented in Pascal simply doesn't
exist in most modern languages, because its semantics are way
confusing. The name given to this technique varies; here's a couple of
