自己编写的一段简单爬虫，代码运行之后显示
Process finished with exit code 0，，，就是没有结果
debug显示如下Connected to pydev debugger (build 203.7717.65)
网络上的pydt试过，删除.idea试过，版本也跟新了，个人认为应该是main（）函数问题，但是不知道哪里出错了，希望来个大佬指点一下下面是代码
import urllib.request,urllib.parse,urllib.error
from bs4 import BeautifulSoup as bs
def main():
#爬取的网址
url="http://data.eastmoney.com/cjsj/gdp.html"
headers={ #模拟浏览器头部
"User-Agent":"Mozilla / 5.0(Windows NT 10.0;Win64;x64) AppleWebKit / 537.36(KHTML, likeGecko) Chrome / 88.0"
".4324.182Safari / 537.36"
}
def get_data():
datalist=[]
for i in range(0,3):
pass
soup=bs(html,"html.parse")
print(soup.title)
def askURL(url):
req=urllib.request.Request(url=url,headers=headers)
html=""
try:
response=urllib.request.urlopen(req)
html=response.read().decode("utf-8")
print(html)
except urllib.error.URLError as e:
if hasattr(e,"code"):
print(e.code)
if hasattr(e,"reason"):
print(e.reason)
return html
if __name__ == '__main()__':
askURL(url)
get_data()
