# 1. content /text  的区别
# print(response.content)  # content 拿到的字节
response.encoding = 'gbk'
# print(response.text)  # text 拿到的文本信息


soup  = BeautifulSoup(response.text,'html.parser')

# tag = soup.find(id='auto-channel-lazyload-article')  # 找惟一的值,缩小范围
# h3 = tag.find(name='h3',class_ ='')  # class是关键词因此要加下划线, 或者使用下面的方式
# h3 = tag.find(name='h3',attrs= {'class':''})  #
# print(h3)
