RuntimeError：此事件循环已在 python 站点映射中运行

Question

程序代码

import sys
import logging
from pysitemap import crawler
import pandas
df = pandas.read_excel(r'absoltepath')
for index, row in df.iterrows():
    #row name where excel data exist
    Url=row['data']
if __name__ == '__main__':
    if '--iocp' in sys.argv:
        from asyncio import events, windows_events
        sys.argv.remove('--iocp')
        logging.info('using iocp')
        el = windows_events.ProactorEventLoop()
        events.set_event_loop(el)
    #storing name    
    crawler(Url, out_file=f'{index}sitemap.xml')

错误

我找到了自己的解决方案

import sys
import logging
from pysitemap import crawler
import pandas
if __name__ == '__main__':
    if '--iocp' in sys.argv:
        from asyncio import events, windows_events
        sys.argv.remove('--iocp')
        logging.info('using iocp')
        el = windows_events.ProactorEventLoop()
        events.set_event_loop(el)
df = pandas.read_excel(r'absolutepath')
for index, row in df.iterrows():
    #row name where excel data exist
    Url=row['data']
    #storing name    
    crawler(Url, out_file=f'{index}sitemap.xml')
