Hey everyone. I've been coding for about a month now. Trying to figure out the assignment I got this week. THe assignment asked me to find if there were any shutouts in a simulation of games and report them. I defined shutout() and Summary(). I feel I am headed in the right direction. I just need a few more pointers.
from random import random
def main():
printIntro()
probA, probB, n = getInputs()
winsA, winsB = simNGames (n, probA, probB)
printSummary(winsA, winsB)
Summary(shutoutsA, shutoutsB)
def printIntro():
print("THis program simulates a game of racquetball between two")
print('players called "A" and "B". The ability of each player is')
print("the player wins the point when serving. Player A alwyas")
print("has the first serve.")
def getInputs():
#Returns the three simulation parameters
a = float(input("What is the prob. player A wins a serve? "))
b = float(input("What is the prob. player B wins a serve? "))
n = int(input("How many games to simulate? "))
return a, b, n
def simNGames(n, probA, probB):
#Simulates n games of racquetball between players whose
# abilities are represented by the probability of winning a serve.
#Returns number of wins for A and B
winsA = winsB = 0
for i in range(n):
scoreA, scoreB = simOneGame(probA, probB)
if scoreA > scoreB:
winsA = winsA + 1
else:
winsB = winsB + 1
return winsA, winsB
def simOneGame(probA, probB):
#Simulates a single game of racquetball between players whose
# abilities are represented by theprobability of winning a serve.
#Returns final scores for A and B
serving = "A"
scoreA = 0
scoreB = 0
shutoutsA = 0
shutoutsB = 0
while not gameOver(scoreA,scoreB):
if serving == "A":
if random() < probA:
scoreA = scoreA + 1
else:
serving = "B"
else:
if random() < probB:
scoreB = scoreB + 1
else:
serving = "A"
return scoreA, scoreB
def shutout(scoreA, scoreB):
shutoutsA = 0
shutoutsB = 0
while simNGames(probA, probB):
if scoreA == 0:
shutoutsB = shutoutsB + 1
if scoreB == 0:
shutoutsA = shutoutsA + 1
return shutoutsA, shutoutsB
def gameOver(a, b):
#a and b represent scores for a racquetball game
#Returns True if the game is over, False otherwise.
return a==15 or b==15
def printSummary (winsA, winsB,):
#Prints a summary of wins for each player.
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 Summary (shutoutsA, shutoutsB):
print(shutoutsA)
print(shutoutsB)
