Everything in Python is passed by reference.  Always.

However, some of those "things" can't be changed, so it may or may not be
possible to do what you want.  Strings can't be changed, so strictly
speaking it's not possible to do what you ask below.  Lists can be changed,
so you could modify them in-place as shown in your C code.  Perhaps you
could explain what it is you're trying to accomplish and we could explain
how it is typically done with Python?
