Python获取基金网站网页内容、使用BeautifulSoup库分析html操作示例

#引入包
from urllib.request import urlopen
response = urlopen("http://fund.eastmoney.com/fund.html")
html = response.read();
#这个网页编码是gb2312
#print(html.decode("gb2312"))
#把html内容保存到一个文件
with open("1.txt","wb") as f:
  f.write(html.decode("gb2312").encode("utf8"))
  f.close()

from bs4 import BeautifulSoup
# 读取文件内容
with open("1.txt", "rb") as f:
  html = f.read().decode("utf8")
  f.close()
# 分析html内容
soup = BeautifulSoup(html,"html.parser")
# 取出网页title
print(soup.title) #<title>每日开放式基金净值表 _ 天天基金网</title>
# 基金编码
codes = soup.find("table",id="oTable").tbody.find_all("td","bzdm")
result = () # 初始化一个元组
for code in codes:
  result += ({
    "code":code.get_text(),
    "name":code.next_sibling.find("a").get_text(),
    "NAV":code.next_sibling.next_sibling.get_text(),
    "ACCNAV":code.next_sibling.next_sibling.next_sibling.get_text()
   },)
# 打印结果
print(result[0]["name"])
