This is a MonteCarlo-Simulation for Texas Holdem Poker!
Download packages from: https://github.com/worldveil/deuces
For testing you should update his packages to Python 3.
# How to use the class:
mc = MonteCarlo(times=10000) # 'times' says how many times it should play
equity = mc.preflop(card1='Ad', card2='Ah', total_villains=4) # Calculates the equity of ace of diamond and ace of hearts when you play against 4 opponents.
print('Equity:', round(equity*100, 3), '%') # Prints out the equity in formatted form!
# This Monte Carlo is really slow however I did it for fun :) !
