How to make cards work in python

This is my code so far:

import sys
import os
import random
Question():
    os.system('cls')
    SQ=input('Do you want to play blackjack y/n')
    if(SQ == y or SQ == Y):
        StartGame()
    if(SQ == n or SQ == N):
        sys.exit()
    if(SQ != n and SQ != N and SQ != y and SQ != Y):
        print('You did answer the question with a y or a n which correspond to yes and no accordingly')
        Question()
Question()

StartGame():
    slot1=False
    slot2=False
    slot3=False
    slot4=False
    slot5=False
    slot6=False
    slot7=False
    slot8=False
    slot9=False
    slot10=False
    slot11=False
    slot12=False
    slot13=False
    slot14=False
    slot15=False
    slot16=False
    slot17=False

    slot26=False
    slot27=False
    Slot28=False
    slot29=False
    slot30=False
    slot31=False
    slot32=False
    slot33=False
    slot34=False

    slot45=False
    slot46=False
    slot47=False
    slot48=False
    slot49=False
    slot50=False
    slot51=False
    slot52=False

    aceHEART = randrange(1, 52)
    aceHEART

I don't understand the correct way to make the slots and a random number generator together to make a random shuffle. How can i make it so it does not try to put more than one card in one slot. I also do not know how to manage these cards in a more efficient way. I am making a blackjack game in python and i do not know the correct way to approach this. Please help me in the best way you can.
