Question

所以我一直在讨论这个问题，在搜索了其他多个问题之后找不到我需要的答案。

我已经设置了一个4位数随机数生成器的任务，然后用户必须尝试猜测数字。他们每次尝试都会说出他们得到了多少数字以及他们所处的位置。此数字也需要处于正确的位置。

这是我目前的代码。

import random as r
def GetNumber():
    number = [r.randint(0, 9), r.randint(0, 9), r.randint(0, 9), r.randint(0, 9)]
    return number

def Choices():
    randomNumber = GetNumber()
    userChoice = list(input("Enter 4 numbers\n")) #Allows the user to input a number 4 digits long
    userChoice = [int(i) for i in userChoice]
    if userChoice == randomNumber:
        print("Congratulations! You chose the right number")

提前致谢：）

Answer 1

您可以zip随机数和用户的选择并比较两对：

>>> number = [4, 3, 9, 1]
>>> choice = [1, 3, 4, 1]
>>> [n == c for n, c in zip(number, choice)]
[False, True, False, True]
>>> sum(n == c for n, c in zip(number, choice))

要获得匹配数字的总数，无论其位置如何，您都可以通过Counter同时输入数字和用户的选择，并与&进行交集：

>>> from collections import Counter
>>> Counter(number) & Counter(choice)
Counter({1: 1, 3: 1, 4: 1})
>>> sum((Counter(number) & Counter(choice)).values())

Answer 2

这是我的看法。

import random as r


def GetNumber():
    return [r.randint(0, 9) for i in range(4)]


def Choices():
    randomNumber = GetNumber()
    userChoice = [int(i) for i in list(input("Enter 4 numbers\n"))]
    n = 0
    while userChoice != randomNumber:
        hits = [str(i+1) for i in range(4) if userChoice[i] == randomNumber[i]]
        if hits:
            print('You got position(s) {} correct'.format(', '.join(hits)))
        else:
            print('You got all of them wrong!')
        userChoice = [int(i) for i in list(input("Enter 4 numbers\n"))]
        n += 1
    print("Congratulations! You found the right number in {} turns!!".format(n))

Choices()

代码已经重新构建了一段时间，直到用户实际找到了密码。这只是一个框架，您可以在其上进行一些实验，并尝试在用户交互或其他方面进一步优化它。

如果有任何不清楚的地方，请告诉我。干杯！

我认为关键是使用一串数字而不是数字数据类型。这是一个有效的例子。你可以通过比较数字来做到这一点，但在这种情况下，我们并不关心数字值这么多的字符模式。

from random import choice
from string import digits


def is_digits(string):
    """Return true if all characters are digits, otherwise false"""

    return all([char.isdigit() for char in string])


def get_number(length):
    """Return a string of digits with the number of characters equal to length"""

    return ''.join(choice(digits) for i in range(length))


def guess():
    """Receive and evaluate guesses for match to randomly generated number"""

    guess = ''
    miss_char = '-'
    miss_message = 'Try again.'
    win_message = 'Congratulations! You chose the right number.'
    answer_length = 4
    answer = get_number(answer_length)
    while guess != answer:
        guess = raw_input('Enter {0} numbers: '.format(len(answer)))
        if len(guess) != len(answer) or is_digits(guess) is False:
            continue
        matches = [answer[i]
                   if answer[i] == guess[i]
                   else miss_char
                   for i in range(len(answer))]
        matches_string = ''.join(matches)
        message_base = 'Matched digits: {0}.'.format(matches_string)
        if guess != answer:
            print(' '.join([message_base, miss_message]))
            guess = ''
        else:
            print(' '.join([message_base, win_message]))

guess()

import random as r
def GetNumber():
    number = r.randint(0000, 9999)
    return str(number).zfill(4)

def Choices():
    randomNumber = GetNumber()
    print type(randomNumber),randomNumber
    userChoice = str(input("Enter 4 numbers\n")).strip("\n") #Allows the user to input a number 4 digits long
    for a,b in zip(userChoice,randomNumber):
      if not a==b:
        print "{0} not match {1}".format(a,b)
    if userChoice==randomNumber:
      print "Congratulations! You chose the right number"
