Python 高低数猜谜游戏

Question

在这个程序中，你想到数字，计算机猜测。在游戏开始之前，计算机会询问它猜到了多少。如果计算机输了，它会询问正确答案是什么。它还会检查以确保答案是合法的，如果不合法，就会指出它。如果用户给出的答案不一致，计算机会指出并停止播放。

我的问题是，当我运行程序时，如果我说“更高”或“更低”，当计算机询问我的数字是否更高/更低/与某个数字相同时，比如 50，我稍后可以说我的数字是50 它告诉我我赢了，而不是说“那不可能；你说它高于/低于 50！”我该如何解决这个问题？

print("Think of a number between 1 and 100 and I'll guess it.")
total = int(input("How many guesses do I get? "))

h = "higher"
l = "lower"
s = "same"
low = 0
high = 100
hls = ""

guess_count = 0

average = 0

while guess_count < total and hls != s:
    average = (high + low) // 2
    hls = input("Is the number higher, lower, or the same as " + str(average) + "? ")
    if hls == h:
        low = average
    elif hls == l:
        high = average
    guess_count += 1
    if high - low == 1:
        break
if high - low == 1:
    print("Wait; how can it be both higher than " + str(low) + " and lower than " + str(high) + "?")
elif hls == s:
    print("I won!")
else:
    answer = int(input("I lost; what was the answer? "))
    if answer < low:
        print("That can't be; you said it was higher than " + str(low) + "!")
    elif answer > high:
        print("That can't be; you said it was lower than " + str(high) + "!")
    elif answer != average:
        print("Well played!")

Answer 1

我运行了您的代码，其中包含一堆打印件，以检查其执行时的变量。这种行为

Think of a number between 1 and 100 and I'll guess it.
How many guesses do I get? 5
Is the number higher, lower, or the same as 50? lower
High is: 50, low is: 0, average is: 50
Is the number higher, lower, or the same as 25? higher
High is: 50, low is: 25, average is: 25
Is the number higher, lower, or the same as 37? higher
High is: 50, low is: 37, average is: 37
Is the number higher, lower, or the same as 43? higher
High is: 50, low is: 43, average is: 43
Is the number higher, lower, or the same as 46? higher
High is: 50, low is: 46, average is: 46
I lost; what was the answer? 50
High is: 50, low is: 46, average is: 46
Well played!

所以，当计算机丢失时，average 是 46，它会通过这些条件：

if answer < low:
    print("That can't be; you said it was higher than " + str(low) + "!")
elif answer > high:
    print("That can't be; you said it was lower than " + str(high) + "!")
elif answer != average:
    print("Well played!")

low 是46，答案是50，所以第一个条件是False。 high 是 50 而我的答案是 50 所以第二个条件是 False。但是，average 是 46，不等于我的 answer 是 50。 Well played! 是最终结果。

将elif answer > high: 更改为elif answer >= high:，您将获得预期的结果。然后把elif answer < low:改成elif answer <= low:。

Answer 2

这里的问题是，为了让计算机程序知道您对某个值给出了错误的响应（例如，说“50 太低”而实际上答案是 50），它需要记录它的猜测以及你对这些猜测的反应。

因此，在它进行猜测并且您获得“较低”或“较高”响应后，您可以将猜测放入 low_guesses 或 high_guesses 列表中，然后在游戏结束时检查这些列表。你可以有这样的东西：

low_guesses = []
high_guesses = []

while True:  # breaks out when user types "same"
    response = input("Is the number higher, lower, or the same as " + str(guess) + "? ")
    if response == "lower":
        # Add the guess to the low_guesses array:
        low_guesses.append(guess)
    elif response == "higher":
        # Add the guess to the high_guesses array:
        high_guesses.append(guess)
    else:
        # Secret number found, so break out of loop:
        break

# Outside of the loop, examine your low_guesses and high_guesses lists.

您可以检查列表，确保low_guesses 的所有元素都小于密码，并且high_guesses 的所有元素都大于密码。如果不是这样，你就知道有问题了。

（另外，一些建议：请不要将变量命名为l 或lst。它们看起来非常像1 或1st，这使得阅读您的代码更难阅读，即使在阅读您的代码的人已经知道它们代表变量名。）
