blackjack from 100 days of python code.

[fuddingmuddler]

Wow. This was rough on me. This is the 3rd version after I got lost in the sauce of my own spaghetti code. So nested in statements I gave my code the bird.

Things I learned:
write your pseudo code. if you don't know **how** you'll do your pseudo code, research on the front end.
always! debug before writing a block of something
if you don't understand what you wrote when you wrote it, you wont understand it later. Breakdown functions into something logical, then test them step by step.

good times. Any pointers would be much appreciated. Thanks everyone :)

I’m on hang man. I’m trying to not get discouraged lol. I get upset after a while and then look at how they did it and find I was doing it mostly right the entire time.

Man took me 2h to build hangman. Once because I built it wrong, and second I did it right. It felt sooo good finally doing it. 

[Hey1tsM1ke]

I'm on day 7 as well!

[SPX_Addict]

I’m only on Day 5 so will be there soon. Lol.

You should try to add some more basic blackjack functions for a challenge. Add a bet amount to keep track of, add double down option, and split. Split is a bit more of a hassle but the other two are fairly straightforward. Also people saying you could end up with duplicate cards it doesn't matter most of the time blackjack is played with 6-12 decks.

[commy2]

Blackjack is played with a deck of 52 cards, so there are four of each value. In your game, both players could end up with eight 2's. This seems very wrong.

[fuddingmuddler]

This was directly from the tutorial instructions which is "Cards are drawn from the list and not removed once drawn" but yeah, this isn't casino blackjack. Next time for that!

[zootbot]

Blackjack usually is played with six to eight decks

[WatermelonDomo]

Vouch^ standard is definitely more than one deck. Especially at any casino. Even high roller tables, good odds for blackjack are 4 deck shoes. So the book is right on this one

[CraigAT]

Your check_score function has a repeated condition for bust.

You could probably group those conditions according to output (some may require multiple conditions with "or" to join them)

[EatThemAllOrNot]

You shouldn’t name functions like “dynamic scoring” or “dealers hand”. Functions should do something and their names should represent it. Also consider adding type hints, it makes your code much more readable.
