我的 python 代码中出现无效语法

Question

所以，我一直在编写代码，但遇到了问题。 我会得到一个无效的语法。 我怎样才能解决这个问题？

print ("Ok, type away")
    number1 = input("Input the first number \n")
    symbol = input("Input your desired operation (+,-,*,/) \n")
    number2 = input("Input the second number \n")
    if symbol == "+":
        output = (int(number1) + int(number2))
    elif symbol == "-":
        output = (int(number1) - int(number2))
    elif symbol == "*":
        output = (int(number1) * int(number2))
    elif symbol == "/":
        output = (int(number1) / int(number2))

    else:
        print ("Something went wrong, ty again")
        number1 = input("Input the first number \n")
        symbol = input("Input your desired operation (+,-,*,/) \n")
        number2 = input("Input the second number \n")
        if symbol == "+":
            output = (int(number1) + int(number2))
        elif symbol == "-":
            output = (int(number1) - int(number2))
        elif symbol == "*":
            output = (int(number1) * int(number2))
        elif symbol == "/":
            output = (int(number1) / int(number2))
    print ("I'm thinking, Please be Patient")
    time.sleep ((random.randint(2,9))

    print ((output))

注意：这是最后一次打印。

最后一个print之前的行有不平衡的括号。
