在簡單的Python程序中處理用戶輸入

Question

我正在製作一個程序，使用列表爲用戶提供一個從1到10的隨機整數作爲直徑，並且他們必須使用Pi作爲3計算周長。到目前爲止，所有工作都正常除了有關糟糕投入的事情。當用戶回答問題時，無論答案如何，它都表示這是不正確的。

有機會得到一些幫助嗎？這裏是我的代碼：

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 drawSquare(): 
    for i in range(4): 
     turtle.begin_fill() 
     turtle.pendown() 
     turtle.forward(50) 
     turtle.left(90) 
     turtle.end_fill() 
    turtle.right(360/correct) 


turtle.penup() 
turtle.setpos(-700,-200) 
turtle.fillcolor("green") 


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) 



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 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

的return cirAnswer語句從askCir丟失。此外，如果用戶間無效答覆多次，則應在askCir中有一個循環。
