完善球赛程序，测试所写程序，所有函数测试结果
代码：
from random import random

try:

except:
print("Error")
结果：
用ruquests的get函数访问谷歌网站20次，打印返回状态，text（）内容，计算text（）属性和content属性所返回网页内容的长度
代码：
import requests
for i in range(1,21):
r = requests.get("https://www.google.cn/")
r.raise_for_status()
r.encoding='utf-8'
print(r.status_code)
print(r.text)
len1=len(r.text)
len2=len(r.content)
print('text()属性所返回的长度{}'.format(len1))
print('content()属性所返回的长度{}'.format(len2))
结果：
