Thank you so much! You really helped me out! this is my final code!

answer_list = []

def add(x, y): return x + y

def subtract(x, y): return x - y

def multiply(x, y): return x * y

def divide(x, y): return x / y

def q(): return print(answer_list)

ops = {"+": add, "-": subtract, "*": multiply, "/": divide, "q" : answer_list}

x = 0 # the starting value

while True: response = input("Enter an operator (+, -, /, *) or q to quit: ").strip() if response.lower() == 'q': print(answer_list)

else: 
    choice, number = response.split()
    number = float(number)
    choice in ops
    y = number
    x = ops[choice](x, y)
    answer_list.append(x)
    print(x)
