I'm attempting to create 5 card stud poker game, I'm almost in the final step of it but I am not understanding how to implement it.
Evaluate each players hand to determine winner(This is where my difficulty reside at the moment)

Sorry if the code is messy and long, still getting used to all this. I would appreciate any input.

This is what i have so far...

I've done this several times before, but not in Python. A simple approach is to give each hand a numerical ranking, and there are a couple of ways to do that.

One way is to assign each hand a number, specifically the number of hands it beats. Thus 7-5-4-3-2 offsuit gets rank 0 and a royal flush gets rank 2598956 since there are 2598960 possible 5-card hands and 4 possible royals. I have a C program that actually generates every possible hand and does this.

Another, somewhat simpler way is to assign each hand a floating point value derived from the major type (bust=0, pair=1, flush=5) etc. and the rank of the cards kind of as you would use yourself.
Here are some examples, where I'm assigning "values" of deuce=0, trey=1 .. king=11, ace=12:

1 pair: base value 1.0 to which you add:

• X/13.0 where X is the "value"what you have a pair of
• K1/(13.0*13.0) where K1 is the "value" of the highest kicker
• K2/(13.0*13.0*13.0) where K2 is the "value" of the second highest kicker
• K3/(13.0*13.0*13.0*13.0) where K3 is the "value" of the bottom kicker

So JJK53 becomes 1.758796960890725, if my math is correct. (1.0 + 9/13.0 + 11/(13.0*13.0) + 3/(13.0*13.0*13.0) + 1/(13.0*13.0*13.0*13.0))

2 pair, QQ55J, becomes

• 2.0 for 2 pair base value PLUS
• 10/13. because Queen is worth 10 PLUS
• 3/(13.0*13.0) because a Five is worth 3, PLUS
• 9/(13.*13.*13.) because a Jack is worth 9

... for a total value of 2.7910787437414655, again if my math is correct.

As you can see, you need separate pieces of code to evaluate separate hand types. Straights are pretty easy to evaluate, just look at the top card (but remember A-2-3-4-5 has top card 5, not A, so is worth base 4.0+3/13.0 since a Five is "worth" 3.)

While a bit tedious, something like the above returns you a number corresponding to a hand such that the better hand always has the higher number. In Python, I would not calculate these values directly but instead first calculate a sequence for each hand type so JJK53 above would turn into (1,9,11,3,1) and QQ55J would turn into (2,10,3,9) and a wheel would be (4,3). Then have a general routine to do all the arithmetic on the sequence, just to separate the arithmetic from the hand-specific problem of ranking each type of hand.
