无论我输入比赛多少场,它都只比赛一场就结束了
我查看了很久,真的不知道是哪里出了问题
如果您不介意我占用您五分钟时间,可以帮我看看,我哪里错了吗?
谢谢谢谢谢谢谢谢谢!!
因为你将 simNGames 函数的 return 放入了 for 循环中,导致执行一次循环就遇到 return 返回了
def simNGames(n, probA, probB):
winsA, winsB = 0, 0
for i in range(n):
scoreA, scoreB = simOneGame(probA, probB)
if scoreA > scoreB:
winsA += 1
else:
winsB += 1
return winsA, winsB
参考代码:from random import random
def printIntro():
print('这个程序模拟两个选手A和B的某种竞技比赛')
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)')
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('模拟比赛场次:'))
return a, b, n
def simNGames(n, probA, probB):
winsA, winsB = 0, 0
for i in range(n):
scoreA, scoreB = simOneGame(probA, probB)
if scoreA > scoreB:
winsA += 1
else:
winsB += 1
return winsA, winsB
def gameOver(a, b):
return a == 15 or b == 15
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()
