第一次爬虫与测试

一、游戏测试

测试方法：运用try和expect

from random import random
def main():
    printInfo()
    probA,probB,m,n = getInput()
    winsA,winsB = simNGames(m,n,probA,probB)
    printSummary(winsA,winsB)
def printInfo():
    print("这个程序模拟两个选手A和B的羽毛球竞技比赛")
    print("程序需要两个选手的能力值0-1") 
    print("规则：三局两胜--21分制")
try:
     printInfo(x)
except:
    print('printInfo error')
 
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(x)
except:
    print('getInput error')
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(500)
except:
    print('printSummary error')
 
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)
 
            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
try:
    simNGames(1000, 0.1)
except:
    print('simNgame error')   
     
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( 0.1)
except:
    print('simOneGame errror')
def gameOver(a,b):
    if(a>=20 or b>=20):
        if(abs(a-b)==2 and a<=29 and b<=29):
            return True

（2）访问网页主页

① 导入库

from requests import get

② 设定url, 并使用get方法请求页面得到响应

url = "http://www.baidu.com"
r = get(url, timeout=3)
print("获得响应的状态码：", r.status_code)
print("响应内容的编码方式：", r.encoding)

运行结果：

获得响应的状态码： 200
响应内容的编码方式： ISO-8859-1

③ 获取网页内容

url_text = r.text
print("网页内容：", r.text)
print("网页内容长度：", len(url_text))

运行结果：

网页内容： <!DOCTYPE html><html> <head> ...  äº¬ICPè¯030173å·  ... </body> </html>

网页内容长度： 2381
