1.完善并测试球赛程序
from random import random
#第一阶段
def printIntro():
print("学号尾数是37")
print("这个程序模拟两个选手A和B的羽毛球比赛")
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）")
try:
printIntro()
except:
print("printIntro Error")
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
try:
getInputs()
except:
print("getInputs Error")
def simNGames(n, probA, probB):
winsA, winsB = 0, 0
for i in range(n): #将模拟n场比赛分解为n次模拟一场比赛
scoreA, scoreB = simOneGame(probA, probB)
if scoreA > scoreB:
winsA += 1
else:
winsB += 1
return winsA, winsB
try:
simNGames(1000, 0.7, 0.6)
except:
print("getInputs Error")
def printSummary(winsA, winsB):
n = winsA + winsB
print("羽毛球比赛分析开始，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(652, 348)
except:
print("Error")
def main():
printIntro()
probA, probB, n = getInputs()
winsA, winsB = simNGames(n, probA, probB)
printSummary(winsA, winsB)
#第二阶段
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
try:
simOneGame(0.7, 0.6)
except:
print("simOneGame Error")
#第三阶段
def gameOver(a,b):
if (a>=20 and b>=20):
if(abs(a-b)==2 and a<=29 and b<=29):
return True
else:
return a==30 or b==30
else:
return False
try:
gameOver(30,27)
except:
print("Error")
main()
2.采用requests库的get函数访问360搜索网页
import requests
for i in range(20):
r = requests.get("http://www.so.com/")
r.encoding= ‘utf-8‘
print(r.text)
print(type(r.text))
print(len(r.text))
print(type(r.content))
print(len(r.content))
结果显示：

3.用HTML完成计算要求
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>菜鸟教程(runoob.com)39</title> </head> <body> <h1>我的第一个标题</h1> <p id="first">我的第一个段落。</p> </body> <table border = "1"> <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> </table> </html>
结果显示
4.爬中国大学排名网站内容
import requests
from bs4 import BeautifulSoup
allUniv = []
def getHTMLText(url):
try:
r = requests.get(url,timeout=30)
r.raise_for_status()
r.encoding = ‘utf-8‘
return r.text
except:
return ""
def fillUnivList(soup):
data = soup.find_all(‘tr‘)
for tr in data:
ltd = tr.find_all(‘td‘)
if len(ltd) == 0:
continue
singleUniv = []
for td in ltd:
singleUniv.append(td.string)
allUniv.append(singleUniv)
def printUnivList(num):
print("{1:^2}{2:{0}^10}{3:{0}^6}{4:{0}^4}{5:{0}^10}".format(chr(12288),"排名","学校名称","省市","总分","培养规模"))
for i in range(num):
u = allUniv[i]
print("{1:^4}{2:{0}^10}{3:{0}^5}{4:{0}^8.1f}{5:{0}^10}".format(chr(12288),u[0],u[1],u[2],eval(u[3]),u[6]))
def main(num):
url = "http://www.zuihaodaxue.com/zuihaodaxuepaiming2018.html"
html = getHTMLText(url)
soup = BeautifulSoup(html,"html.parser")
fillUnivList(soup)
printUnivList(num)
main(10)
