how this function is working without parameters?

Question

def add1():
    c=a+b
    print("sum is",c)

a=int(input("Enter a:"))
b=int(input("Enter b:"))
add1()

the program is about adding two numbers. and displaying result. I took a and b input from the user, and directly called the function without passing arguments. its working. Could you please explain why this is workig?

I'm also confused when to use arguments and when not?

Variable a and b are global as they are not declared in any indent, so all your function does is add variable a and b if you named your variable any thing other than a it b it would not work
