Python re-introduces the overridden own function

Fortunately, this problem is easy to solve, we only need to use __builtins__:

From __builtins__ import int as Py_int

That way we can re-use Python's int again, but at this point it's called Py_int.

The most common reason for a function or variable to be overwritten is the use of "*" when referencing:

From something import *

When we use import like this, we cannot clearly guide which variables or function are introduced, nor do we know whether those variables or function will overwrite the original variables or function. So this is one of the main reasons why "*" is not recommended when using import.

In Python 3, you can use Builtins instead of __builtins__.
