在使用“绝对初学者第三版的 Python 编程”一书学习 Python 的过程中，并努力应对已经设定的挑战。

我必须创建一个数字猜测程序，玩家选择一个数字，程序尝试通过选择一个随机数来猜测它，然后使用更高或更低的问题来接近数字。我已经弄清楚了大部分，但我正在为更高或更低的循环而苦苦挣扎。我遇到的麻烦是我无法让程序不高于或低于倒数第二个猜测，即

我的号码是 78 台计算机选择 50 我说较高的计算机选择 80 我说较低的计算机可以选择 12（当我不希望它低于 50 时。

我正在使用 Python 3.1

这是代码的副本。

import random

computer_tries = 0
player_number = None
computer_guess = random.randint(1, 100)

print(

    """)

question = None
while question != ("yes"):
    question = input("Has the player picked a number? ")
    question = question.lower()
    if question == "yes":
        print("\nI will now guess your number!!!\n")
        while player_number == None:
            computer_tries += 1
            print(computer_guess, "\n")
            confirmation = input("Is this the correct number? ")
            confirmation = confirmation.lower()
            if confirmation == "yes":
                player_number = computer_guess
                if computer_tries < 2:
                    print("I did it! I guessed your number was", computer_guess,

我发现您的代码存在以下问题：

  1. 您的随机数生成器仅绑定在数字谱的一侧，例如random.randint(0, lower)- 所以它忽略了higher边界。同样对于computer_guess = random.randint(higher, 101)。
  2. 我建议你初始化higher和lower.
  3. 一些调试有帮助:)

这是工作代码：

import random

computer_tries = 0
player_number = None
computer_guess = random.randint(1, 100)

print(
    """
    Welcome Player to the fabulous number guessing game.
    Please allow me to show you my incredible deduction skills
    """)

question = None
lower = 0 # initial lower guess
higher = 101  # initial higher guess
while question != ("yes"):
    question = input("Has the player picked a number? ")
    question = question.lower()
    if question == "yes":
        print("\nI will now guess your number!!!\n")
        while player_number == None:
            computer_tries += 1
            print(computer_guess, "\n")
            confirmation = input("Is this the correct number? ")
            confirmation = confirmation.lower()
            if confirmation == "yes":
                player_number = computer_guess
                if computer_tries < 2:
                    print("I did it! I guessed your number was", computer_guess,
                           "and it only \ntook me", computer_tries,
                           "try to get it right!")
                else:
                    print("I did it! I guessed your number was", computer_guess,
                           "and it only \ntook me", computer_tries,
                           "tries to get it right!")
            else:
                higher_lower = None
                while higher_lower not in ("higher", "lower"):
                    higher_lower = input("Is my guess higher or lower"
                                + " than your number? ")
                    higher_lower = higher_lower.lower()
                    if higher_lower == "higher":
                        higher = computer_guess
                        computer_guess = random.randint(lower+1, higher-1)
                    elif higher_lower == "lower":
                        lower = computer_guess
                        computer_guess = random.randint(lower+1, higher-1)
                    else:
                        print("Please choose either higher or lower.")
                    print("DEBUG: number must be " + str(lower) + " < x < " + str(higher))

您永远不会存储可能数字的上限和下限。在您的示例中，一旦您的程序选择 50 并且您说“更高”，您就需要在某处存储“数字肯定高于 50”的信息。当您回答“较低”时也是如此。

您必须存储诸如 min_comp_guess 和 max_comp_guess 之类的内容。然后，当您要“猜测”数字时，您必须为有效范围生成它（显然 min_comp_guess 到 max_comp_guess）。

我永远是第二！:)

我可能完全错了，但是在测试您的代码时，我发现通过选择程序编号高于我选择的编号，它会增加数字而不是可能会减少，而不是使它更接近我猜测的数字。我创建的一个类似的更高/更低的程序也有同样的问题，为了解决这个问题，我只是切换了大于和小于符号，希望你觉得这很有帮助，并可以将它应用到你的程序中。
