How to add and multiply arguments? [closed]

I'm trying to make it so it will add or multiply based on if the result is over or under 1000. Sorry if my coding is atrocious. I'm still very new to this.

def multi_sol(*num):
    product1 = 1
    for i in num:
        if product1 <= 1000:
            product1 *= i
        return product1
    else:
        for i in num:
            if product >= 1000:
                product1 += i
            return product1

result = multi_sol(20, 50)
print("The result is", result)
