在Python程序中处理用户输入

Question

我正在制作一个程序，它会给用户一个从1到10的随机整数作为直径，然后用户需要用3作为圆周率来计算圆的周长。在我的代码中，当用户输入一个字符串而不是整数时，程序会提示用户输入一个整数。如果用户随后输入了正确的答案，程序却说这是错误的答案。我希望程序能正确地说出答案是对的。有没有人能帮我一下？这是我的代码：

import turtle
import random
turtle.speed("fastest")


pi = 3
minNumber = 4
maxNumber = 10
score = 0
listNmbers = []
a = [1,3,5,7,9]

red = random.random()
green = random.random()
blue = random.random()

num1 = random.choice(a)


def askCir(cirAnswer):
    try: 
        user = input("What is the circumference of a circle if the diameter is " + str(num1) + " and Pi is 3?")
        cirAnswer = int(user)   
    except:
        print("Please input a number only!")
        cirAnswer = 0;
        cirAanswer = askCir(cirAnswer)
    return cirAnswer
    cirAnswer = 0;
    cirAnswer = askCir(cirAnswer)



print("Welcome! What is your name??")
name = str(input())
print("Hello", name,"you need to calculate the circumference of a circle when given a diameter. To calculate the circumference, use the equasion; Pi x Diameter (Pi = 3")


def getNumbers():
    num = input("how many questions would you like to answer? (Pick between 5 and 10)")
    try:
        numbers = int(num)
    except:
        print("That is not a number!")
        return getNumbers()
    goodInput = minNumber < numbers < maxNumber

    if not goodInput:
        print ("That is not between 5 and 10. Please input an integer between 5 and 10.")
        return getNumbers()
    else:
        return numbers
numbers = getNumbers()    


for i in range(numbers):
    red = random.random()
    green = random.random()
    blue = random.random()
    turtle.color(red,green,blue)
    num1 = random.choice(a)
    correct = num1 * 3

    cirAnswer = 0;
    cirAnswer = askCir(cirAnswer)
    print(str(correct))

    if float (cirAnswer) == correct:
        print("That's Correct! Well Done")
        score = score + 1
    else:
        print("Sorry that is incorrect")

    for k in range(correct):
        turtle.color(red,green,blue)
        drawSquare()

    turtle.penup()
    turtle.forward(150)

Answer 1

你的程序不工作是因为有个拼写错误。

cirAanswer = askCir(cirAnswer) 这行代码应该改成

cirAnswer = askCir(cirAnswer)

简单来说，你的新答案被赋值给了一个新变量 cirAanswer，所以总是返回0。
