When you use Python, program in Python and not C. What do you need the
memory location of a variable for? Python, like Java and .NET is a
higher level language. You're not supposed to worry about things like
the physical location in memory. There's probably some ugly hack using
ctypes, or just writing the code in C but I don't know enough about
Python's C API to know what it is.

FWIW, even the id(x) == address of x is only an implementation detail
of CPython. Other Python implementations don't use that scheme.
