Using a variable outside of a defined function
Clash Royale CLAN TAG#URR8PPP Using a variable outside of a defined function
If I had a function that I made:
def a():
n = 2*2
How could I access n out of the function without calling a?
Why would you want to?

You cannot. You will need to define the variable outside of the function, or call the function and return it.
You need to return it, so do:
def a():
n = 2*2
return n
print(a())
Output:
4
You can also do print, but return is better, check this: What is the formal difference between "print" and "return"?
print
return

A related question comes to mind, although that's about accessing a variable inside a function when you do call the function, so it's not really a duplicate.
