Question

您好我知道这已被问过几次，但我找不到答案。问题是反向猜测我的数字游戏。代码执行程序但不是以“类似人”的方式。如果数字是50并且它猜测20它响应更高，例如计算机说30，它得到的响应更低它猜测15.如何解决这个问题？练习来自：绝对初学者的Python。有人能帮我吗？请以简单的方式，因为否则我会跳过书中的内容。我想你可以通过查看代码来了解我所知道的和不知道的内容。请帮帮我......

代码：

#Guess My Number
#
#The computer picks a random number between 1 and 100
#The playes tries to guess it and the coputer lets
#the player know if the guess is too high, too low
#or right on the money

print ("\t// // // // // // // // // //")
print ("\tWelcome to 'Guess My Number'!")
print ("\tComputer VS Human")
print ("\t// // // // // // // // // //")
name = input("What's your name?")
print ("Hello,", name)
print ("\nOkay, think of a number between 1 and 100.")
print ("I'll try to guess it within 10 attemps.")

import random

#set the initial values

the_number = int(input("Please type in the number to guess:"))
tries = 0
max_tries = 10
guess = random.randint(1, 100)

#guessing loop
while guess != the_number and tries < max_tries:
    print("Is it", guess,"?")
    tries += 1

    if guess > the_number and tries < max_tries:
        print ("It's lower")
        guess = random.randint(1, guess)
    elif guess < the_number and tries < max_tries:
        print ("It's higher")
        guess = random.randint(guess, 100)
    elif guess == the_number and tries < max_tries:
        print("Woohoo, you guessed it!")
        break
    else:
        print("HAHA you silly computer it was", the_number,"!")

input ("\n\nTo exit, press enter key.")

Answer 1

您需要跟踪最高可能值和最低可能值，以便您可以智能地猜测。

最初，最低可能值为1，最高值为100。假设你猜50，计算机响应“更高”。你的两个变量怎么了？最低可能值现在变为50，因为该数字不能低于该值。最高值保持不变。

如果计算机响应“较低”，则会发生相反的情况。

然后你会在最低和最高值之间猜测：

random.randint(lowest, highest)

您的猜测将按预期进行。

Answer 2

阅读Binary Search应该指出正确的方向。

Answer 3

通常情况下，每次进行新的猜测时，这些游戏的工作方式都是使可能的数字范围更小。即。

1st guess = 20
guess is too low 
--> range of guesses is now (21, 100)

2nd guess = 45
guess is too high
--> range of guesses is now (21, 44)
etc...

在你的测试中，你忘记了所有以前的猜测，所以它不能这样做。您可以尝试跟踪范围的下端和下端：

lower_range, higher_range = 1, 100
max_tries = 10

#guessing loop
while tries < max_tries:
    guess = random.randint(lower_range, higher_range)
    print("Is it", guess,"?")
    tries += 1

    if guess > the_number:    
        print ("It's lower")
        higher_range = guess - 1

    elif guess < the_number:
        print ("It's higher")
        lower_range = guess + 1

    else:    # i.e. correct guess
        print("Woohoo, you guessed it!")
        input ("\n\nTo exit, press enter key.")
        sys.exit(0)

print("HAHA you silly computer it was", the_number,"!")

还稍微整理了while循环。

通常，这些游戏也会利用二进制搜索方法。为了好玩，你可以试着实现这个:)希望这会有所帮助！
