python代码函数不适用于算术测验，密码不适用

Question

请给我一些代码方面的帮助，因为函数对NumberError()不起作用。关键是，如果在回答数学测验时你错误地键入了一个字母，它会说“请键入一个数字”，但是我无法让它工作，因为不断出现错误：

Traceback (most recent call last):
  File "C:/Users/Helen/Documents/Computer Science Summer Task/Helen_Summer Tasks-1_2_3.py", line 77, in <module>
    StudentAnswer = int(input("Please answer the question: "))
ValueError: invalid literal for int() with base 10: 'g'

以下是我迄今为止所做的尝试：

def NumberError():
    if StudentAnswer not in Turns '1,2,3,4,5,6,7,8,9,10':
            print('Please enter a NUMBER.')
    else:
        return ("\nQuestion")  

此外，密码选项访问测验不完全工作：这里是我到目前为止，我会很感激，如果我可以有一些帮助，我需要做的正确和我做错了什么。你知道吗

from tkinter import *
import tkinter as tk
window = tk.Tk()


import os

#Must Access this to continue.


def checkPassword():
    password = "Starfish"
    def enteredPassword():
        passwordEntry.get()
    if password == enteredPassword:
        confirmLabel.config(text="Access granted")
    else:
        confirmLabel.config(text="Access denied")

passwordLabel = tk.Label(window, text="Password:")
passwordEntry = tk.Entry(window, show="*")

button = tk.Button(window, text="Enter", command=checkPassword)
confirmLabel = tk.Label(window)

passwordLabel.pack()
passwordEntry.pack()
button.pack()
confirmLabel.pack()

window.mainloop()

这是我到目前为止的全部代码：

from tkinter import *
import tkinter as tk
window = tk.Tk()

#Must Access this to continue.


def checkPassword():
    password = "Starfish"
    def enteredPassword():
        passwordEntry.get()
    if password == enteredPassword:
        confirmLabel.config(text="Access granted")
    else:
        confirmLabel.config(text="Access denied")

passwordLabel = tk.Label(window, text="Password:")
passwordEntry = tk.Entry(window, show="*")

button = tk.Button(window, text="Enter", command=checkPassword)
confirmLabel = tk.Label(window)

passwordLabel.pack()
passwordEntry.pack()
button.pack()
confirmLabel.pack()

window.mainloop()

for n in Turns:
    Number1 = random.randint(1, 10)
    Number2 = random.randint(1, 10)
    Number3 = random.randint(1, 3)

    if Number3 == 1:
        Answer = Number1 + Number2

    elif Number3 == 3:
        Answer = Number1 * Number2
        Sign = " x "
    print("\nQuestion", n, "\n", Number1, Sign, Number2)
    StudentAnswer = int(input("Please answer the question: "))
    print("The correct answer is:", Answer)
    if StudentAnswer == Answer:
        Score = Score + 1
        print("Well Done, that is correct!")
    else:
        print("Sorry that is incorrect!")
def NumberError():
    if StudentAnswer not in Turns '1,2,3,4,5,6,7,8,9,10':
            print('Please enter a NUMBER.')
    else:
        return ("\nQuestion")  

print("\nName:", Name)
print("\nClass:", Class)
print("\nScore:", Score)

谢谢！你知道吗

Answer 1

您可以测试输入类型，而不是将其转换为int

i = input("Please answer the question: ")
if(not type(i) is int):
    print('Please enter a NUMBER.')
