if statement issue in python class

When you run the code you should take a card from a set deck and from that I want it to display a write or wrong answer depending on if you type red or black by reading it, but no matter what I do it won't run the if statement.

import random

class Card(object):
    def __init__(self, suit, num, color):
        self.suit = suit
        self.num = num
        self.color = color

    def show(self):
        input("Red or Black ")

        print("{} of {} ".format(self.num,self.suit))

        if self.suit == "Hearts" or self.suit == "Diamonds":`enter code here`
           self.color = "Red"
           print("The color is {}".format(self.color) )
        elif self.suit == "Spades" or self.suit == "Clubs":`enter code here`
           self.color = "Black"
           print("The color is " + self.color )


class Deck(object):
    def __init__(self):
        self.cards = []
        self.build()

    def build(self):
        for i in ["Spades", "Hearts", "Diamonds", "Clubs"]:
            for a in ["Red", "Black"]:
                for j in range(0, 14):
                    self.cards.append(Card(j,i, a))

    def shuffle(self):
        for i in range(len(self.cards)-1, 0, -1):
            r = random.randint(0, i)
            self.cards[i], self.cards[r] = self.cards[r], self.cards[i]
    def show(self):
       for c in self.cards:
           c.show()

    def draw(self):
        return self.cards.pop()

    #def color(self):

class Player():
    def __init__(self):
        self.hand = []

    def pick(self, deck):
        self.hand.append(deck.draw())
        return self

    def showHand(self):
        while True:
        # x = input("Red or Black?: ").lower()
         for card in self.hand:
           card.show()
         #if x == 'red':
    
deck = Deck()    
deck.shuffle()    
player = Player()    
player.pick(deck)    
player.showHand()
