Question

我正在为我的班级写一个彩票计划。我已经查看了stackoverflow的答案，但我发现的所有内容都已提升。我想知道是否有办法缩短if语句并减少它们。

import random

def lottery():                      
    lottoNumber1 = random.randint(1,50)
    print(lottoNumber1)
    lottoNumber2 = random.randint(1,50)
    print(lottoNumber2)
    lottoNumber3 = random.randint(1,50)
    print(lottoNumber3)
    return lottoNumber1,lottoNumber2,lottoNumber3

userChoice1 = int(input('Choose a number between 1 and 50: '))
userChoice2 = int(input('Choose a number between 1 and 50: '))
userChoice3 = int(input('Choose a number between 1 and 50: '))

lottoNumber1, lottoNumber2, lottoNumber3 = lottery()

if userChoice1 == lottoNumber1:
if userChoice1 == lottoNumber2:
    if userChoice1 == lottoNumber3:
        if userChoice2 == lottoNumber1:
            if userChoice2 == lottoNumber2:
                if userChoice2 == lottoNumber3:
                    if userChoice3 == lottoNumber1:
                        if userChoice3 == lottoNumber2:
                            if userChoice3 == lottoNumber3:

        print('You win $1,000')
else:
    print('Try it again!')

main()

Answer 1

如果你创建了两个集合，一个持有彩票号码，另一个持有用户选择，那么一个if语句可以比较它们：

import random

# Use sets to ensure lottery numbers and user choices are unique
lottoNumbers = set()
userChoices = set()

while len(lottoNumbers) < 3:
    lottoNumbers.add(random.randint(1,50))

while len(userChoices) < 3:
    userChoices.add(input('Choose a number between 1 and 50: '))

print(lottoNumbers)
print(userChoices)

if lottoNumbers == userChoices:
    print('You win $1,000')

Answer 2

这对你有用。

from random import randint

def lottery():                      
    return [randint(1, 50) for x in range(3)]

user_choices = list(map(int, [input('Choose a number between 1 and 50: ') for x in range(3)]))
lotto_numbers = lottery()
print(user_choices)
print(lotto_numbers)
if any(user_choice == lotto_number for user_choice, lotto_number in zip(sorted(user_choices), sorted(lotto_numbers)))

如果陈述以及如何缩短它们？
