calculate()函数的第24行第10行上的

问题。它说选择没有定义。

我尝试过更改与每个运算符相关的定义变量和整数变量。

def start():
    print("Hey, I'm your calculator... \n")

    num1 = float(input("Enter your first number: "))
    num2 = float(input("Enter your second number: "))
    print("Operator list: \n 1. Addition + \n 2. Subtraction - \n 3. Multiply * \n 4. Division / \n")
    choice = int(input("Type the letter corresponding to your selection: "))

add = 1
subtract = 2
multiply = 3
divide = 4

def calculate():
    if choice == add or 1:
        print(num1 + num2)
    elif choice == subtract or 2:
        print(num1 - num2)
    elif choice == multiply or 3:
        print(num1 * num2)
    elif choice == divide or 4:
        print(num1 / num2)
    else:
        print("Oops! Please enter a valid operator: '+', '-', '*', or '/'")
        start()

start()
calculate()

回溯(最近通话最近一次):

  

文件“ C:/Users/hkben/OneDrive/Desktop/PythonFiles/calculator.py”,第29行,在       计算()     计算中的文件“ C:/Users/hkben/OneDrive/Desktop/PythonFiles/calculator.py”,第16行       如果选择==添加或1:   NameError:名称“ choice”未定义
