01. List Methods
- Here are some other common list methods.
- list.append(elem) - adds a single element to the end of the list. Common error : does not return the new list, just modifies the original
- list.insert(index,elem) - inserts the element at the given index, shifting elements to the right.
- list.extend(list2) - adds the elements in list2 to the end of the list. Using + or += on a list is similar to using extend().
- list.index(elem) - searches for the given element from the start of the list and returns its index. Throws a ValueError if the element does not appear (use 'in" to check without a ValueError).
- list.remove(elem) - searches for the first instance of the given element and removes it (throws ValeError if not present)
- list.sort() 0 sorts the list in place (does not return it). (The sorted() function shown later is preferred.)
- list.reverse() - reverses the list in place (does not return it)
- list.pop(index) - removes and returns the element at the given index. Returns the rightmost element if index is omitted (roughly the opposite of append()).

## The deck is unlimited in size.
## There are no jokers.
## The Jack/Queen/King all count as 10.
## The the Ace can count as 11 or 1.
## Use the following list as the deck of cards:
## cards = [11, 2, 3, 4, 5, 6, 7, 8, 9, 10, 10, 10, 10]
## The cards in the list have equal probability of being drawn.
## Cards are not removed from the deck as they are drawn.
##################### Hints #####################
#Hint 1: Go to this website and try out the Blackjack game:
# https://games.washingtonpost.com/games/blackjack/
#Then try out the completed Blackjack project here:
# http://blackjack-final.appbrewery.repl.run
#Hint 2: Read this breakdown of program requirements:
# http://listmoz.com/view/6h34DJpvJBFVRlZfJvxF
#Then try to create your own flowchart for the program.
#Hint 3: Download and read this flow chart I've created:
# https://drive.google.com/uc?export=download&id=1rDkiHCrhaf9eX7u7yjM1qwSuyEk-rPnt
#Hint 4: Create a deal_card() function that uses the List below to *return* a random card.
#11 is the Ace.
import random
from replit import clear
from art import logo
def deal_card():
"""Returns a random card from the deck."""
cards = [11, 2, 3, 4, 5, 6, 7, 8, 9, 10, 10, 10, 10]
card = random.choice(cards)
return card
#Hint 6: Create a function called calculate_score() that takes a List of cards as input
#and returns the score.
#Look up the sum() function to help you do this.
def calculate_score(cards):
"""Take a list of cards and return the score calculated from the cards"""
#Hint 7: Inside calculate_score() check for a blackjack (a hand with only 2 cards: ace + 10) and return 0 instead of the actual score. 0 will represent a blackjack in our game.
if sum(cards) == 21 and len(cards) == 2:
return 0
#Hint 8: Inside calculate_score() check for an 11 (ace). If the score is already over 21, remove the 11 and replace it with a 1. You might need to look up append() and remove().
if 11 in cards and sum(cards) > 21:
cards.remove(11)
cards.append(1)
return sum(cards)
#Hint 13: Create a function called compare() and pass in the user_score and computer_score. If the computer and user both have the same score, then it's a draw. If the computer has a blackjack (0), then the user loses. If the user has a blackjack (0), then the user wins. If the user_score is over 21, then the user loses. If the computer_score is over 21, then the computer loses. If none of the above, then the player with the highest score wins.
