How to set constants in module by function and use it in another function in python?

Question

I want to get in print A2. What is the best way to do that?
(for any numbers and types of constants):

VAR1=1
VAR2=2

def choose_var(variation):
    if variation == 1:
        VAR1 = "A"
        VAR2 = 2
    elif variation ==2:
        VAR1 = "B"
        VAR2 = 3 
        
def get_some_stuff():
    return str(VAR1 + VAR2)
    
choose_var(1)
print(get_some_stuff())

without passing VAR1 and VAR2 to get_some_stuff()

You need to make both variables global, by default they’re local to the method

def choose_var(variation):
    global VAR1, VAR2
    if variation == 1:
        VAR1 = "A"
        VAR2 = 2
    elif variation == 2:
        VAR1 = "B"
        VAR2 = 3

And fix the concatenation between int and str

def get_some_stuff():
    return f"{VAR1}{VAR2}"
