Can we use already defined variables in arguements of def() ?

Question

Like

Var1 = 123
Var2 = 456
def add(Var1, Var2):
return (Var1 + Var2)

Answer 1

You can 👌
But I recommend not to, we need to be clear about which variabe we want to work on. If you want to work soleluly with the global <Var1> and <Var2>, then you don't need any parameter in function `add`.
