The problem i see with using globals() is that it can overwrite a previously
defined function or key within the global namespace, making the code
potentially dangerous and wild with exploits.

Because if you're in the global scope, locals() returns globals(), which
is a real namespace and modifying it works.

It's legal, but it's (usually) a very bad idea - at the top-level, it

The real question is not how, but why?
Anyway, assuming you want them to be global variables:

As sets are unordered, you may as well have
a = 3
m = 7
p = 1
or any other permutation. You need some sequences instead. E.g.
n = [
