Example game

We're going to make an example text-game of Catan using PyCatan

First, create a new file.

game.py

def main():
	print("Playing Catan!")

if __name__ == "__main__":
	main()

Now let's set up a new game of Catan

game.py

from PyCatan import CatanGame

def main():

	num_of_players = int(input("How many players are playing? "))

	game = CatanGame(num_of_players)
