1.
（1）测试
simOneGame(probA,porbB)
def printIntroduce(): print('学号39，This program simulates a game between two players,A and B') print('Probability(a number between 0~1) is used') try: printIntroduce() except: print("error")
2)
getInput()
def getInput(): 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):")) m=eval(input("比赛的局数：")) n = eval(input("模拟比赛的场次:")) return a,b,m,n try: getInput() except: print("error")
3) printSummary(winsA,winsB)
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)) try: printSummary(6,4) except: print("error")
4）simNGames(m,n,probA,proB)
def simNGames(m,n,probA,probB): winsA,winsB = 0,0 wa,wb=0,0 for i in range(n): for i in range(m): #scoreA,scoreB = simOneGame(probA,probB) scoreA,scoreB=probA,probB if scoreA > scoreB: wa += 1 else: wb += 1 if wa==2: winsA+=1 wa,wb=0,0 break if wb==2: winsB+=1 wa,wb=0,0 break return winsA,winsB m=eval(input()) n=eval(input()) probA=eval(input()) probB=eval(input()) print(simNGames(m,n,probA,probB))
（2）访问网站20次
1 import requests 2 def gethtml(url): 3 try: 4 r=requests.get(url) 5 r.raise_for_status() 6 r.encoding='utf-8' 7 return r.text,r.status_code,len(r.text),len(r.text),len(r.content) 8 except: 9 return "" 10 11 url="https://cn.bing.com/" 12 for i in range(20): 13 print(i) 14 print(gethtml(url))
结果：
（3）html
from bs4 import BeautifulSoup import re soup=BeautifulSoup("<head><title>菜鸟教程(runoob.com)</title></head><body><h1>我的第一个标题</h1><p id=frist>我的第一个段落。</p></body><tr><td>row 1,cell 1</td><td>row 1,cell 2</td></tr><tr><td>row 2,cell 1</td><td>row 2,cell 2</td></tr></body></table>","html.parser") print(soup.head,"08") print(soup.body) print(soup.find_all(id="china")) r=soup.text pat = re.findall(u'[u1100-uFFFDh]+?',r) print(pat)
