第八周的实例13,老师的代码直接复杂粘贴运行结果和视频一样,但是如果换成我自己敲的,却很不一样。
老师的代码
[Python] 纯文本查看 复制代码 # MatchAnalysis.py
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("模拟比赛的场次: "))
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

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))
