【问题描述】：

我只是遇到了 print("Out of Guesses!\nYou Lose, Try Again!") 的问题。每当玩家猜不透时，它会打印出所有 print print 语句两次，输出如下：

Too Low!  
Out of Guesses!  
You Lose, Try Again!  
Too Low!

什么时候应该打印：

Out of Guesses!
You Lose, Try Again!

代码：

import random

number = random.randint(0,20)
player = ""
guess_count = 0
guess_limit = 5
out_guesses = False

while player != number and not out_guesses:
    if guess_count < guess_limit:
        player = int(input("Input Your Guess: "))
        guess_count += 1

    else:
        out_guesses = True
        print("Out of Guesses!\nYou Lose, Try Again!")

    if player == number:
        print("You Win!")
    if player < number:
        print("Too Low!")
    if player > number:
        print("Too High!")

【问题讨论】：

因为你没有停止程序...它一直在检查猜测。你应该在Out of guesses 打印之后break
你需要在最后使用elif和else而不是两个if(s)。
或者，将 guess_count 检查移动到实际猜测检查之后

【解决方案1】：

在out_guesses 场景中：

  if player == number:
        print("You Win!")
    if player < number:
        print("Too Low!")
    if player > number:
        print("Too High!")

这个代码块被执行了两次而不是一次。你必须用逻辑阻止它。这是一个示例：

import random

number = random.randint(0, 20)
player = ""
guess_count = 0
guess_limit = 5

while player != number:
    if guess_count < guess_limit:
        player = int(input("Input Your Guess: "))
        guess_count += 1
        if player == number:
            print("You Win!")
        if player < number:
            print("Too Low!")
        if player > number:
            print("Too High!")
    else:
        print("Out of Guesses!\nYou Lose, Try Again!")
        break
