保持列表中的項目，而循環

Question

，所以我想在這裏我除了列表保存所有的總和導致循環::

def calc(): 

addition = [] 
sub = [] 
multi = [] 
division = [] 
firstNumber =float(input("Enter the first number: \n")) 
oper =input("choose the operation (+ , - , * , /) \n") 
secondNumber =float(input("Enter the second number: \n")) 

if oper == "+": 
    x = firstNumber + secondNumber 
    addition.append(x) 
    print(x) 
    print(addition) 
elif oper == "-": 
     firstNumber - secondNumber 
elif oper == "*": 
     firstNumber * secondNumber 
elif oper == "/": 
    if secondNumber != 0: 
     firstNumber/secondNumber 
    else: 
     print("Can't divide by zero") 

while 0<1: 
calc() 
msg = input("Do you want to continue? y/n") 
if msg == "y": 
    calc() 
elif msg =="n": 
    break 
else: 
    print("wrong choise") 

所以，如果我的第一相加結果是5，第二個是每個週期10 ... 加入列表是[5，10，...]

把你所有的while循環中的代碼，除了上4行代碼的。
