Python 如何修复基于随机数生成器不重复的if语句

我正在做一个问答游戏，在询问首都城市和国家之间交替进行。它们应该随机交替，因此我使用随机数生成器，但是if语句不会根据随机数生成器的输出重复。（我对编码相当陌生，如果这太长，很抱歉）

代码如下：

import random
from random import randrange

quest_one = int(input('How many questions? '))

for i in range(quest_one):
    number = (randrange(2))



Country_main = {
    "Australia" : 'Canberra',
    'india' : 'New Delhi',
    'France' : 'Paris',
    'Japan' : 'Tokyo',
    'China': 'Beijing',
    'USA': 'Washington',
    'England': 'London',
    'Russia': 'Moscow',
    'Germany': 'Berlin',
    'Brazil': 'Brasilia',
    'Bangladesh': 'Dhaka'
}

Capital_main = {
    'Canberra': 'Australia',
    'New Delhi': 'India',
    'Paris': 'France',
    'Tokyo': 'Japan',
    'Beijing': 'China',
    'Washington': 'USA',
    'London': 'England',
    'Moscow': 'Russia',
    'Berlin': 'Germany',
    'Brasilia': 'Brazil',
    'Dhaka': 'Bangladesh'
}

def Capital_of():
    rando = random.choice(list(Country_main.items()))
    ans = input("What is the capital city of " + rando[0] + '? ')
    if rando[1] in ans:
        print('correct')
        #Change to add value to score later
    elif rando[1] not in ans:
        print('wrong')
    return


def Country_of():
    randy = random.choice(list(Capital_main.items()))
    ansy = input("Which country has the capital city " + randy[0] + '? ')
    if randy[1] in ansy:
        print('correct')
        # Change to add value to score later
    elif randy[1] not in ansy:
        print('wrong')
    return



if number == 1:
    Capital_of()
if number == 0:
    Country_of()

问题在于代码的结构方式。您的

for

循环应该是询问指定数量问题的主循环

按照现在的设置方式，for循环将生成

x

数量的随机数，然后退出循环并运行程序的其余部分

# current program

for i in range(quest_one):
    number = (randrange(2))

#
# more code
#

if number == 1:
    Capital_of()
if number == 0:
    Country_of()

您的

if

语句需要嵌套在

for

循环中，以便不断提问

我重新格式化了代码，因此

if

语句嵌套在

for

循环中。
试试这个：

import random
from random import randrange

Country_main = {
    "Australia" : 'Canberra',
    'india' : 'New Delhi',
    'France' : 'Paris',
    'Japan' : 'Tokyo',
    'China': 'Beijing',
    'USA': 'Washington',
    'England': 'London',
    'Russia': 'Moscow',
    'Germany': 'Berlin',
    'Brazil': 'Brasilia',
    'Bangladesh': 'Dhaka'
}

Capital_main = {
    'Canberra': 'Australia',
    'New Delhi': 'India',
    'Paris': 'France',
    'Tokyo': 'Japan',
    'Beijing': 'China',
    'Washington': 'USA',
    'London': 'England',
    'Moscow': 'Russia',
    'Berlin': 'Germany',
    'Brasilia': 'Brazil',
    'Dhaka': 'Bangladesh'
}


def main():
    num_questions = int(input('How many questions? '))

    for i in range(num_questions):
        number = (randrange(2))

        if number == 1:
            capital_of()
        else:
            country_of()


def capital_of():
    rando = random.choice(list(Country_main.items()))
    ans = input("What is the capital city of " + rando[0] + '? ')
    if rando[1] in ans:
        print('correct')
        #Change to add value to score later
    elif rando[1] not in ans:
        print('wrong')
    return


def country_of():
    randy = random.choice(list(Capital_main.items()))
    ansy = input("Which country has the capital city " + randy[0] + '? ')
    if randy[1] in ansy:
        print('correct')
        # Change to add value to score later
    elif randy[1] not in ansy:
        print('wrong')
    return


if __name__ == '__main__':
    main()
