Python竞猜游戏，计算竞猜次数

Question

我的计算机科学入门老师给了我们一个骰子猜谜游戏挑战，虽然我已经设法弄清楚了大部分组件，但最后一部分是返回正确的数字(一旦他们猜到了)以及他们花了多少次尝试才能弄清楚。我的代码返回了所有这些，但它不会考虑猜测同一个数字的人是否猜测了两次。有没有办法告诉他们，在忽略任何重复数字的情况下，他们花了多少次猜测才找到一个数字？

这是我到目前为止所拥有的代码：

import random

give_number = input("We will roll a 6 sided dice. What do you think the number will be?\n ")
guess_number = 1

dice = random.randint(1,6)
while give_number != dice:
    if give_number > dice:
        give_number = input("Sorry, that answer is too high! Try again!\n ")
        guess_number = guess_number +1
    if give_number < dice:
        give_number = input("Sorry, that answer is too low! Try again!\n ")
        guess_number = guess_number +1

print "Congratulations, you were right, the answer was {}! It took you {} tries.".format(dice, guess_number)

Answer 1

为了检测重复的猜测，我们必须跟踪所有以前的猜测。

我们只需要知道一个特定的数字以前是否被猜测过-而不是它出现了多少次。

这是使用set的最佳位置(请参阅Python docs)。

从一个空集开始(而不是从guess_number = 1开始)，然后将每个猜测添加到这个集合中。

一旦这个人猜对了，你就可以检查集合的大小-这是猜测的次数，忽略重复项。

我建议使用列表来追加猜测。我这样修改了你的代码(在我的例子中是Python 3)：

import random

give_number = int(input("We will roll a 6 sided dice. What do you think the number will be?\n "))
guess_number = 1
guessList = []
guessList.append(give_number)

dice = random.randint(1,6)
while give_number != dice:
    if give_number > dice:
        give_number = int(input("Sorry, that answer is too high! Try again!\n "))
        #guess_number = guess_number + 1
        if give_number not in guessList:
            guessList.append(give_number)
    if give_number < dice:
        give_number = int(input("Sorry, that answer is too low! Try again!\n "))
        #guess_number = guess_number + 1
        if give_number not in guessList:
            guessList.append(give_number)

if give_number not in guessList:
    guessList.append(give_number)
print ("Congratulations, you were right, the answer was {}! It took you {} tries.".format(dice, len(guessList)))

如果你想检查输入是整数还是在你的范围内，你可以看看下面的代码：

import random

def inputIsInt(inpStr): # checks if the input is an integer in range (1, 7).
    try:
        if int(inpStr) in range(1, 7):
            return True
        else:
            return False
    except ValueError:
        return False

give_number = input("We will roll a 6 sided dice. What do you think the number will be?\n ")
while not inputIsInt(give_number):
    print("Sorry, your input is not an integer or out of range")
    give_number = input("We will roll a 6 sided dice. What do you think the number will be?\n ")

guessList = []
guessList.append(int(give_number))
dice = random.randint(1,6)

while int(give_number) != dice:
    if int(give_number) > dice:
        give_number = input("Sorry, that answer is too high! Try again!\n ")
        while not inputIsInt(give_number):
            print("Sorry, your input is not an integer or out of range")
            give_number = input("We will roll a 6 sided dice. What do you think the number will be?\n ")
        if int(give_number) not in guessList:
            guessList.append(int(give_number))
    if int(give_number) < dice:
        give_number = input("Sorry, that answer is too low! Try again!\n ")
        while not inputIsInt(give_number):
            print("Sorry, your input is not an integer or out of range")
            give_number = input("We will roll a 6 sided dice. What do you think the number will be?\n ")
        if int(give_number) not in guessList:
            guessList.append(int(give_number))

if int(give_number) not in guessList:
    guessList.append(int(give_number))
print ("Congratulations, you were right, the answer was {}! It took you {} tries.".format(dice, len(guessList)))

您还可以将guess_number变量移到if语句之外，这样：

    import random

    give_number = input("We will roll a 6 sided dice. What do you think the number will be?\n ")
    guess_number = 0

    dice = random.randint(1,6)
    while give_number != dice:
        guess_number = guess_number + 1
        if give_number > dice:
            give_number = input("Sorry, that answer is too high! Try again!\n ")
            #guess_number = guess_number +1
        if give_number < dice:
            give_number = input("Sorry, that answer is too low! Try again!\n ")
            #guess_number = guess_number +1

    print "Congratulations, you were right, the answer was {}! It took you {} tries.".format(dice,guess_number)
