help with simulation program

Postby ceeilly32 » Sun Nov 17, 2013 2:06 am

I am trying to simulate games and print the results of how many serves each 4 player served, and also I changed the winning rule for each game so that if the difference between scores of the teams is more than 5 then the leading team wins that particular game. I believe I did that correctly, but I am unsure. Also, I am trying to show the progress of my program with animation later and I am having trouble finding a function that does that. May you guys help a new beginning programmer? I am kind of lost about what I should do. Thanks!

Code: Select all
from random import random
from random import randrange

def gameOver(a, b):
    if(a > 5 or b > 5):
        return 1
        return 0

def simOneGame(probA_1, probA_2, probB_1, probB_2):

    choose_serve = randrange(1,5)
    if(choose_serve == 1):
        serving = "A_1"
    elif(choose_serve == 2):
        serving = "A_2"
    elif(choose_serve == 3):
        serving = "A_3"
        serving = "A_4"
    scoreA = 0
    scoreB = 0
    while not gameOver(scoreA, scoreB):
        if serving == "A_1":
            if random() < probA_1:
                scoreA = scoreA + 1
                serving = "B_1" or "B_2"
        elif serving == "A_2":
            if random() < probA_2:
                scoreA = scoreA + 1
                serving = "B_1" or "B_2"
        elif serving == "B_1":
            if random() < probB_1:
                scoreB = scoreB + 1
                serving = "A_1" or "A_2"
            if random() < probB_2:
                scoreB = scoreB + 1
                serving = "A_1" or "A_2"
    return scoreA, scoreB

def simNGames(n, probA_1, probA_2, probB_1, probB_2):
    winsA = winsB = 0
    for i in range(n):
        scoreA, scoreB = simOneGame(probA_1, probA_2, probB_1, probB_2)
        if scoreA > scoreB:
            winsA = winsA + 1
            winsB = winsB + 1
    return winsA, winsB

def printSummary(winsA, winsB):
    n = winsA + winsB
    print("\nGames simulated:", n)
    print("Wins for A: {0} ({1:0.1%})".format(winsA, winsA/n))
    print("Wins for B: {0} ({1:0.1%})".format(winsB, winsB/n))

def getInputs():
    a_1 = eval(input("What is the prob. player A_1 wins a serve? "))
    a_2 = eval(input("What is the prob. player A_2 wins a serve? "))
    b_1 = eval(input("What is the prob. player B_1 wins a serve? "))
    b_2 = eval(input("What is the prob. player B_2 wins a serve? "))
    n = eval(input("How many games to simulate? "))
    return a_1, a_2, b_1, b_2, n

def printIntro():
    print("This program simulates a game of racquetball between four")
    print('players called "A_1", "A_2", "B_1", and "B_1", repsectively.  The abilities of each player is')
    print("indicated by a probability (a number between 0 and 1) that")
    print("the player wins the point when serving. Player A always")
    print("has the first serve.")

def main():
    probA_1, probA_2, probB_1, probB_2, n = getInputs()

    winsA, winsB = simNGames(n, probA_1, probA_2, probB_1, probB_2)
    printSummary(winsA, winsB)
