Question

在这个程序中，计算机会猜测数字。在游戏开始之前，计算机会询问获得了多少猜测。如果计算机丢失，它将询问正确的答案是什么。它还会检查以确保答案是合法的，并指出答案是否正确。如果用户给出的答案不一致，则计算机会指出并停止播放。

我的问题是，当我运行该程序时，如果计算机询问我的数字是高/低/还是50，那么我说“高”还是“低”，我以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；您说的是高于/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

这里的问题是，为了使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），则需要记录其猜测以及您对这些猜测的回答。

因此，在进行猜测并获得“较低”或“较高”的响应后，可以将猜测放入low_guesses或high_guesses列表中，然后在末尾检查这些列表游戏的。您可能会遇到这样的事情：

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.

您可以通过确保low_guesses的所有元素都小于秘密数字，并且确保high_guesses的所有元素都大于秘密数字来检查列表。如果那不是真的，那您就知道出了点问题。

（另外，一些建议：请不要命名变量l或lst。它们看起来很像1或1st，以致于很难阅读代码来读取，即使阅读您的代码的人已经知道它们代表变量名。）

Answer 2

我在代码中运行了一堆打印程序，以检查执行时的变量。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!

因此，当计算机丢失且average为46时，它将通过以下条件运行：

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为46，答案为50，因此第一个条件为False。 high是50，我的回答是50，所以第二个条件是False。但是，average是46，不等于我的answer，即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。然后将elif answer < low:更改为elif answer <= low:。
