Blackjack game creation in Python, how to pick two random cards?

I am trying to create blackjack card, but I am having trouble with picking random cards in while loop.

import random

card_dict = {'A': 11, '2':2, '3':3, '4':4, '5':5, '6':6, '7':7, '8':8, '9':9, 'T':10, 'J':10, 'Q':10, 'K':10}

cardcolor = ['S', 'H', 'C', 'D']



player_score = 0
dealer_score = 0


# In here, because I have no idea how to create card number randomly, I created random.choice a lot for dealer to pick up another cards if their card sum is not over 17.
# Is there anyway to write one sentence or few sentences code to pick up random number in while loop?

#For example, if I am using player_num = random.choice(list(card_dict)), and put this in every line where the random number needed, it gave me all same numbers in while-loop

# I am not sure that I explained well, I hope that you get it. Thanks for your reading and help! If you want to know more, please give me a comment.
