存储数字并根据用户输入进行比较

Question

目前正在努力从头开始学习 Python 3.5，并且非常享受这个过程。最新的事情是编写一个执行以下操作的基本程序..

• 让用户想一个介于 1 到 100 之间的数字
• 猜猜是什么
• 要求用户输入“1”如果太低，“3”如果太高，“2”如果 正确
• 根据用户输入提供一个新号码
• 限制自己尝试 10 次，然后羞愧地退出
• 做对了就庆祝

现在我想我已经得到了所有的工作减去更高/更低的功能。我的问题是这个。

注意 这与该主题的其他问题不同，因为我不想输入任何数字供 PC 使用。还希望生成限制在给定值范围内的伪随机数，以供 PC 进行后续猜测。不增加。

“我如何实现一个功能，查看 var 'guess' 并根据用户输入将其修改为更高或更低，同时保持其高于 0 和低于 100”。

代码：

import random  

print("\tWelcome to the psychic computer")
print("\nI want you to think of a number between 1 and 100.")
print("I will try to guess it in 10 or less tries.\n")
print("\n Press 1 for a lower guess, 3 for a higher one and 2 if I get it       right\n")

tries = int(1)

guess = random.randint(1, 100)
print("\nI guess ", + guess, " Is this correct?")


while tries < 10:
    feedback = int (input("\nEnter 1 if too high, 3 if too low or 2 if bang   on\n\n"))
    tries += 1
    if feedback == 1:
        print("Balls! Guess I need to go Higher will", + guess, + "do?")

    elif feedback == 3:
        print("\nSh*te! Lower it is then...")

    elif feedback == 2:
        print("YEEAAAHH BOYEEEE! Told you I was phychic.")
        input("\nHit enter to quit")
        end

    elif feedback != (1,2,3):
        print("Not a valid guess. Try again.")
        break

    if tries >= 9:
        print("\nSh*t, guess I'm not so psychic after all")
    input("\nHit enter to exit")

Answer 1

您可以执行二进制搜索之类的操作。使用 low_number 和 high_number 通过取两者的中间值来计算猜测。这些最初可以设置为 0 和 100。您还应该跟踪您最后的猜测。如果你最后的猜测太低，你可以设置你的 low_number 等于那个guess+1。如果您最后的猜测太高，您可以将 high_number 设置为该 guess-1。

Answer 2

好的，这就是我目前所拥有的。它的工作原理是它将根据用户输入以（半）随机更高或更低的猜测来响应，但尚未将原始猜测存储为参考。我明天会看看那个。再次感谢您的建议。

顺便说一句，一旦工作，我计划使用数学并提出一个解决方案，总能在 x 次尝试中得到正确的结果..

    import random  

    print("\tWelcome to the psychic computer")
    print("\nI want you to think of a number between 1 and 100.")
    print("I will try to guess it in 10 or less tries.\n")
    print("\n Press 1 for a higher guess, 3 for a lower one and 2 if I get it    right\n")

    tries = int()
    guess = random.randint(1, 100)
    high_number = int(100 - guess)
    low_number = int(1 + guess)

    print("\nI guess ", + guess, " Is this correct?")

    while tries < 10:

    feedback = int (input("\nEnter 1 to go higher, 3 to go lower or 2 if bang    on\n\n"))
    tries += 1
    if feedback == 1:
        guess = random.randint(high_number, 100)
        print("Balls! Guess I need to go Higher how about", + guess)

        elif feedback == 3:
            guess = random.randint(1, low_number)
            print("\nSh*te! Lower it is then... what about", + guess)    

        elif feedback == 2:
            print("YEEAAAHH BOYEEEE! Told you I was phychic.")
            input("\nHit enter to quit")
            end

        elif feedback != (1,2,3):
            input("Not a valid guess. Try again.")
            break

if tries >= 9:
    print("\nSh*t, guess I'm not so psychic after all")
input("\nHit enter to exit")
