1）模拟体育竞技分析：（不同学号选做不同题目，必做题）
a.采用乒乓球比赛规则（学号尾号为0,1,2,3同学必做及格题）。
（即：一局比赛：
在一局比赛中，先得11分的一方为胜方；10平后，先多得2分的一方为胜方。
一场比赛：
单打的淘汰赛采用七局四胜制，双打淘汰赛和团体赛采用五局三胜制。）
1.打印程序的介绍性信息式（要求包括你们学号后两位信息）
2.输入I(input)：两个球员（球队）的能力值，模拟比赛的次数
3.处理P(process)：模拟比赛过程
4.输出O(output)：两个球员（球队）获胜的概率（输出谁做的结果截图），
from random import random
def printIntro():
print("这个程序模拟两个选手A和B的乒乓球比赛")
print("程序运行需要A和B的能力值（以0到1之间的小数表示）")
print("作者学号：20")
def getInputs():
a = eval(input("请输入选手A的能力值(0-1): "))
b = eval(input("请输入选手B的能力值(0-1): "))
n = eval(input("模拟比赛的场次: "))
return a, b, n
def simNGames(probA, probB):
winsA, winsB = 0, 0
for i in range(7):
scoreA, scoreB = simOneGame(probA, probB)
if scoreA > scoreB:
winsA += 1
else:
winsB += 1
return winsA, winsB
def simnGames(n,probA,probB):
WinsA,WinsB=0,0
for i in range(n):
winsA, winsB = simNGames(probA,probB)
if winsA>winsB:
WinsA+=1
else:
WinsB+=1
return WinsA,WinsB
def gameOver(a,b):
if a<11 and b<11:
return 0
elif a==11 and b<10 or b==11 and a<10:
return 1
elif a-b==2 and a>11 or b-a==2 and b>11:
return 1
def simOneGame(probA, probB):
scoreA, scoreB = 0, 0
serving = "A"
while not gameOver(scoreA, scoreB):
if serving == "A":
if random() < probA:
scoreA += 1
else:
serving="B"
else:
if random() < probB:
scoreB += 1
else:
serving="A"
return scoreA, scoreB
def printSummary(WinsA, WinsB):
n = WinsA + WinsB
print("竞技分析开始，共模拟{}场比赛".format(n))
print("选手A获胜{}场比赛，占比{:0.1%}".format(WinsA, WinsA/n))
print("选手B获胜{}场比赛，占比{:0.1%}".format(WinsB, WinsB/n))
def main():
printIntro()
probA, probB, n = getInputs()
WinsA, WinsB = simnGames(n, probA, probB)
printSummary(WinsA, WinsB)
main()
input("按下任意键退出程序......")
（2）采用篮球或者足球规则模拟比赛，分析体育竞技规则，模拟比赛。（良好），基本要求同上。
import random
def printIntro():
print("这个程序模拟两支球队A和B的篮球比赛")
print("程序运行需要球队A和B的能力值（以0到1之间的小数表示）")
print("作者学号：20")
def getInputs():
a = eval(input("请输入球队A的能力值(0-1): "))
b = eval(input("请输入球队B的能力值(0-1): "))
n = random.randint(1,200)
return a, b, n
def simOneGame(n,probA, probB):
scoreA, scoreB = 0, 0
serving = "A"
a=0
while (a<=n) or (a>n) and (scoreA==scoreB):
if serving == "A":
if random.random() < probA:
scoreA += 1
else:
serving="B"
else:
if random.random() < probB:
scoreB += 1
else:
serving="A"
a+=1
return scoreA, scoreB
def printSummary(n, scoreA, scoreB):
print("竞技分析开始，共模拟{}个回合".format(n))
print("球队A获得{}分".format(scoreA))
print("球队B获得{}分".format(scoreB))
if scoreA>scoreB:
char='A'
else:
char='B'
print("获胜方是球队{}".format(char))
def main():
printIntro()
probA, probB, n = getInputs()
scoreA, scoreB = simOneGame(n,probA, probB)
printSummary(n, scoreA, scoreB)
main()
input("按下任意键退出程序......")
（3）采用乒乓球、羽毛球、篮球、足球等规则中的一种。同时采用循环赛或者晋级赛形式，模拟分析4个队及以上体育竞技，并输出排名。
from random import random
def printIntro():
print("这个程序模拟四个选手A,B,C和D的乒乓球比赛")
print("程序运行需要A,B,C和D的能力值（以0到1之间的小数表示）")
print("作者学号：20")
def getInputs():
a = eval(input("请输入选手A的能力值(0-1): "))
b = eval(input("请输入选手B的能力值(0-1): "))
c = eval(input("请输入选手C的能力值(0-1): "))
d = eval(input("请输入选手D的能力值(0-1): "))
n = eval(input("模拟每两名选手比赛的场次: "))
return a, b, c, d, n
def simNGames(probA, probB):
winsA, winsB = 0, 0
for i in range(7):
scoreA, scoreB = simOneGame(probA, probB)
if scoreA > scoreB:
winsA += 1
else:
winsB += 1
return winsA, winsB
def simnGames1(n,probA,probB):
WinsA,WinsB=0,0
for i in range(n):
winsA, winsB = simNGames(probA,probB)

WinsA+=1
else:
WinsB+=1
return WinsA,WinsB
def simnGames2(n,probA,probB,WinsA,WinsB):
for i in range(n):
winsA, winsB = simNGames(probA,probB)
if winsA>winsB:
WinsA+=1
else:
WinsB+=1
return WinsA,WinsB
def gameOver(a,b):
if a<11 and b<11:
return 0
elif a==11 and b<10 or b==11 and a<10:
return 1
elif a-b==2 and a>11 or b-a==2 and b>11:
return 1
def simOneGame(probA, probB):
scoreA, scoreB = 0, 0
serving = "A"
while not gameOver(scoreA, scoreB):
if serving == "A":
if random() < probA:
scoreA += 1
else:
serving="B"
else:
if random() < probB:
scoreB += 1
else:
serving="A"
return scoreA, scoreB
import operator
Departs = []
class Department:
