python while循环点系统-运行缓慢

Question

I have to simulate a points game where the first person to reach 11 points and win by 2 clear points wins the game

I have used a function to decide who wins a point

def simulatePoint(winProbabilityA, winProbabilityB):
    rNumber = random.random()
    if rNumber - winProbabilityA <= 0:
            # A wins the game
            return 0
    elif rNumber - winProbabilityA > 0:
            # B wins the game
            return 1

and another one to simulate a game

def simulateGame (playerA_winProb, playerB_winProb):
    gameWon = False
    pointsA = 0
    pointsB = 0

    while gameWon == False:
            # Simulate point
            point = simulatePoint(playerA_winProb, playerB_winProb)
            if point == 0:
                    pointsA += 1
            elif point == 1:
                    pointsB += 1

            # Checks for points to be equal to 11
            if (pointsA == 11) and (pointsA - pointsB >= 2):
                    # A wins the game
                    gameWon = True
                    return 0
            elif (pointsB == 11) and (pointsB - pointsA >= 2):
                    # B wins the game
                    gameWon = True
                    return 1

This is where i believe i am going wrong, i think the while loop is causing the code to run slow

Any help is greatfully accepted

Answer 1

What if the difference becomes greater than or equal to 2, after they have won more than 11 games. So, the logic should have been like this

if (pointsA >= 11) and (pointsA - pointsB >= 2):
...
elif (pointsB >= 11) and (pointsB - pointsA >= 2):
...

Answer 2

I think your code is running infinitely.

Consider: pointsA and pointsB reach 10 and 10 respectively. Now, no matter what player gets the next point, neither of your terminating conditions will be reached because neither pointsA nor pointsB will be 11 and up by 2 at the same time. This creates an infinite loop.

You'd probably want to check if pointsA >= 11 and pointsB >= 11 instead of A == 11 and B == 11 .

Looks like thefourtheye beat me by a bit - he gets my vote.
