如何检查非整数输入并连续运行而不中断或退出？

Question

我试图找到一种方法来防止“播放器”，或用户输入，进入我的游戏非整数的答案。我发现了一个速战速决，但它不会做我想要什么（代码休息，如果用户输入一个非整数的答案），它似乎打破代码的其余部分。我希望用户能够重复尝试（while循环？）并遍历整个代码。感谢您的帮助。

# Generate random number for player to guess.
import random

number = random.randint(1, 3)
print(number)

# Ask player's name and have player guess the number.
welcomeUser = input("Hi, welcome to 'Guess a Number!'. Please tell us your name ")

userName = str(welcomeUser)
userGuess = input("Guess a number from 1 - 3 ")

# Cycle through player's guesses until player enters correct number.
while True:
    if userGuess != userGuess.isdigit():
        input("Sorry you broke the code for entering a non-numeric value")
        break
    elif int(userGuess) > number:
        print("You've guess too high, please try again ")
        userGuess = int(input("Guess a number from 1 - 3 "))
        if userGuess == number:
            print("Congratulations! You've guessed correctly! ")
            break
    elif int(userGuess) < number:
        print("You've guessed too low, please try again ")
        userGuess = int(input("Guess a number from 1 - 3 "))
        if userGuess == number:
            print("Congratulations! You've guessed correctly! ")
            break
    else:
        print("Congratulations " + userName + "! " + "You've guessed correctly! ")
        break
