For those who want to run multiple experiments: I have used "winlist = []" on top, "winlist.append(self.winner[0])" in winning-function (I never had multiple winners, so it worked fine) and put the lines at the bottom in a loop (f.e. "for j in range(0, 20):") and after the loop you can use something like "print(winlist)
print(Counter(winlist).keys())
print(Counter(winlist).values())" to print the winners and how many times each winner won. There are probably way prettier methods but this worked fine for me
