在python程序中处理用户输入

Question

我正在制作一个程序，使用列表给用户一个从1到10的随机整数作为直径，他们必须使用Pi作为3来计算圆的周长。在我的代码中当用户输入字符串而不是整数时，程序会要求用户输入一个整数。如果用户输入正确的答案，程序会说这是一个不正确的答案。我需要程序来说这是正确的。 有什么机会我可以得到一些帮助？这里是我的代码：

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

它不工作，因为你的程序中有一个错字。

cirAanswer = askCir(cirAnswer)需要是

cirAnswer = askCir(cirAnswer)

基本上新的答案被分配给一个新的变量cirAanswer和0总是被返回
