python - 将字符串视为整数

Question

我正在尝试制作一款非常简单的二十一点游戏。当您发到两张牌时，如果它们都是整数或字符串，则一切正常，但如果发到的两张牌是一个字符串和一个整数，我会收到错误消息。

我怎样才能做到，如果你得到一张 7 和一张 Q，那么 Q 将被视为 10，总共给你 17？

#imports
import random

Jack = 10
Queen = 10
King = 10
Ace = 1 or 11

Cards = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 'Jack', 'Queen', 'King', 'Ace']
#Faces = Jack, Queen, King, Ace
print('Welcome to Blackjack!\n\nHere are your cards: \n ')
Card1 = random.choice(Cards)
Card2 = random.choice(Cards)
Total = Card1 + Card2
print(Card1,'and a', Card2, '. Your total is', Total)






#print(int(Jack + Ace))

Answer 1

使用字典将卡片映射到值:

Cards = {"1": 1, "2": 2, "3": 3, "4": 4, "5": 5, "6": 6, "7": 7, "8": 8, "9": 9,
         "10": 10, 'Jack': 10, 'Queen': 10, 'King': 10, 'Ace': 10}

#Faces = Jack, Queen, King, Ace
print('Welcome to Blackjack!\n\nHere are your cards: \n ')
keys = list(Cards)
Card1 = random.choice(keys)
Card2 = random.choice(keys)
Total = Cards[Card1] + Cards[Card2]
print(Card1, 'and a', Card2, '. Your total is', Total)

或者使用.items:

Cards = {"1": 1, "2": 2, "3": 3, "4": 4, "5": 5, "6": 6, "7": 7, "8": 8, "9": 9,
         "10": 10, 'Jack': 10, 'Queen': 10, 'King': 10, 'Ace': 10}

#Faces = Jack, Queen, King, Ace
print('Welcome to Blackjack!\n\nHere are your cards: \n ')
c = list(Cards.items())
Card1 = random.choice(c)
Card2 = random.choice(c)
Total = Card1[1] + Card2[1]
print(Card1[0], 'and a', Card2[0], '. Your total is', Total)
