Can global variable be passed into Python function?

In classic functional programming, the values of variables can't change
but they are still called variables (even though "parameters" might be
more fitting).

Apart from a fact that a C variable has an address (references are
first-class objects, if you will), I really don't see a difference
between a C variable and a Python variable.
