The secret to understanding the global keyword is to understand how
Python namespaces work. The statement "a=5" does not assign a 5 to the
box called "a." Rather it binds the name "a" to the "5" object, which
is immutable and called into existence by the interpreter
implementation.
In other words, it assigns a pointer to the "5" object [otherwise known
as "a 5"] to the box called "a". (And increments its reference count, if
you care about how the CPython garbage collector works)
If everything in Python is an object, how can it assign a pointer?
Especially how do Jython and IronPython assign pointers?
