Question

我通过使用Python重新制作一个名为Dope Wars的游戏来练习我的编码。如果你不熟悉Dope Wars，长话短说 - 你从一个城市到另一个城市买卖毒品。目标是赚取尽可能多的钱，而不是被杀或被捕。我开始让游戏通过命令行播放，并在完成后将其编码到GUI中。代码Im发布有2个城市和2种药物可供购买。命令行会询问您要去哪个城市，是否要购买，想要购买什么以及购买多少。我得到它来更新我存储值的字典，但它不会保存你循环的值，我很确定它是因为使用.update（），但我不知道还有什么用。

所以我基本上在寻找一种方法来保持库存中的价值，以便可以添加和取出，买卖。我还需要建立一个货币系统，随机警察追捕，一家银行，一家医院和一家枪支店，任何有关这些方面的帮助都会有很大帮助。

这是我到目前为止所做的：

import random

#  Stores dope list with prices for each city
nyDope = {'Heroin': random.randrange(1000, 2000), 'Coke': random.randrange(1000, 2000)}
laDope = {'Coke': random.randrange(1000, 2000)}

# Stores references for cities to their dope list
cityDict = {'New York': nyDope, 'Los Angeles': laDope}


# to print out dope list for NY
def ny():
    for i in nyDope:
        print(i + ': ' + str(nyDope[i]))


# To print out dope list for LA
def la():
    for i in laDope:
        print(i + ': ' + str(laDope[i]))

print('Pick your city')
city1 = input()
if city1.lower().startswith('n'):
    ny()
elif city1.lower().startswith('l'):
    la()
else:
    print('Wrong answer, now you have to go to New York')
    ny()

goAgain = True
unitsHeroin = 0
unitsCoke = 0

while goAgain == True:

    inventory = {'Heroin': int(unitsHeroin), 'Coke': int(unitsCoke)}

    print('Type what drug you want to buy:')
    buyDrugs1 = input()
    if buyDrugs1.lower() == 'heroin':
        print('How many?')
        boughtDrugs1 = input()
    elif buyDrugs1.lower() == 'coke':
        print('How many?')
        boughtDrugs1 = input()
    else:
        print("That's not an option")

    if buyDrugs1.lower() == 'heroin':
        inventory.update({'Heroin': int(unitsHeroin) + int(boughtDrugs1)})
    if buyDrugs1.lower() == 'coke':
        inventory.update({'Coke': int(unitsCoke) + int(boughtDrugs1)})

    print('Heroin: ' + str(inventory['Heroin']), '\nCoke: ' + str(inventory['Coke']))

    print('Buy more drugs? y/n')
    goAgain = input()
    if goAgain.lower().startswith('y'):
        goAgain = True
    else:
        goAgain = False
        break

Answer 1

您在每次迭代开始时初始化inventory;在主循环开始之前将初始化移动到。或者，您可以对units变量进行更改，以便在重新创建inventory时，它会使用新值。

Answer 2

这是您更新的代码：

import random

#  Stores dope list with prices for each city
nyDope = {'Heroin': random.randrange(1000, 2000), 'Coke': random.randrange(1000, 2000)}
laDope = {'Coke': random.randrange(1000, 2000)}

# Stores references for cities to their dope list
cityDict = {'New York': nyDope, 'Los Angeles': laDope}


# to print out dope list for NY
def ny():
    for i in nyDope:
        print(i + ': ' + str(nyDope[i]))


# To print out dope list for LA
def la():
    for i in laDope:
        print(i + ': ' + str(laDope[i]))

print('Pick your city')
city1 = input()
if city1.lower().startswith('n'):
    ny()
elif city1.lower().startswith('l'):
    la()
else:
    print('Wrong answer, now you have to go to New York')
    ny()

goAgain = True
unitsHeroin = 0
unitsCoke = 0

inventory = {'Heroin': int(unitsHeroin), 'Coke': int(unitsCoke)}

while goAgain == True:


    print('Type what drug you want to buy:')
    buyDrugs1 = input()
    if buyDrugs1.lower() == 'heroin':
        print('How many?')
        boughtDrugs1 = input()
    elif buyDrugs1.lower() == 'coke':
        print('How many?')
        boughtDrugs1 = input()
    else:
        print("That's not an option")

    if buyDrugs1.lower() == 'heroin':
        inventory['Heroin'] = int(inventory['Heroin']) + int(boughtDrugs1)
    if buyDrugs1.lower() == 'coke':
        inventory['Coke'] = int(inventory['Coke']) + int(boughtDrugs1)

    print('Heroin: ' + str(inventory['Heroin']), '\nCoke: ' + str(inventory['Coke']))

    print('Buy more drugs? y/n')
    goAgain = input()
    if goAgain.lower().startswith('y'):
        goAgain = True
    else:
        goAgain = False
        break
