Red-black trees
Project description
In this course, you will learn how to create a Blackjack game by using Python 3. This is meant to be a fun game, an exercise that can be completed during your weekend. This game will randomly assign cards to the player and dealer. Python Blackjack Game Logic The entire game logic revolves around the dealing of cards and player’s choices for either hitting or standing. As soon as we handle the above two things, we are done for the day.
Blackjack is a simple implementation of the classic red-black tree as astandard Python data structure. A set and a dictionary are included:
Usage
- I am currently learning Python through a course on Udemy and I'm working on a milestone project to create a Blackjack game. The only rule is for me to use Object Oriented Programming and to create classes for things like the Card and Deck.

- I am in the process of writing a blackjack code for python, and i was hoping someone would be able to tell me how to make it: Recognize what someone has typed i.e. 'Hit' or 'Stand' and react accordingly. Calculate what the player's score is and whether it is an ace and a jack together, and automatically wins. Ok, this is what I have gotten so far.
Blackjacks and decks behave just like normal Python sets and dictionaries, buthave different performance characteristics and different requirements forkeys. All keys must be comparable, but need not be hashable:
This does impact heterogeneity somewhat, but shouldn’t be a problem for mostcommon uses. On the other hand, the average and worst-case times for access,membership testing, insertion, and deletion are all logarithmic, which makesblackjacks ideal for storing mappings of data with untrusted keys:
Even on small- to medium-sized sets of data, blackjacks quickly become moreeffective than dictionaries in the face of untrusted input.

Technical information
The specific trees used are left-leaning red-black trees. Red children areopportunistically reduced during balancing if nodes will be recreated anyway;this tends to shorten overall tree height by reducing the number of redchildren. Complexities are as follows:
Operation | Time | Space |
---|---|---|
Lookup | O(log n) | O(1) |
Membership | O(log n) | O(1) |
Insertion | O(log n) | O(log n) |
Deletion | O(log n) | O(log n) |
Update | O(log n) | O(log n) |
Sort | O(1) | O(1) |
Length | O(1) | O(1) |
Sorting according to the provided key function is constant because the tree’straversal order is presorted. Length is recorded and updated on mutation.Nodes are persistent and altering the tree generally requires a logarithmicspace commitment to create new nodes.

Hello everyone.
I am learning Python at the moment and I am liking it, so after finishing the collection course and the Dungeon Game I wanted to test my skills with a BlackJack game.
Here is my code so far:
Blackjack Python 3 Script
I have tested it on my terminal in my virtual environment and I would say it is doing fine.I have added what I will need to do next as comments at the bottom.
Please test it and let me know if you find any bugs that I have missed!! THANKS
Also, as you may remember Kenneth Love , I have asked you about global variables in Python yesterday and the question was because of this project:
Blackjack Python Code
I have to use a few: 4 if I have counted correctly.I have thought (actually still think) that I need those because I will have to use them a lot in the code.
But if there is a better way to do this (which I am pretty sure there is :) ), feel free to let me know.
Thanks
Vittorio
Instead of selecting a card and then removing it as its own step, why not just .pop()
the first occurrence of the card's value?
Awesome work, though! Great to see people come up with brand new creations!
Right, pop is surely needed here.I was wondering about that also because now I don't want to waste the card value as I need it later to check the stats.
ty Kenneth,
good to see you often around the forum
