我正在尝试使用多处理来提高抓取的速度，但是我不知道如何将其集成到我的代码中。

我正在使用Python 3.7

import requests as r
import pandas as pd

pd.DataFrame(data=None,index=None,columns=None,dtype=None,copy=False)

team_ids = [100,200,300,400,500]

d = {'player_id'         : [],'num'               : [],'name'              : []
        }

for t_ in team_ids:
    url = 'http://example_url?team_id='+str(t_)
    req  = r.get(url)
    json = req.json()
    team_id = t_

    for rs in json['team_names']['Results']['row']:

        d['player_id'].append(rs['player_id'])
        d['num'].append(rs['jersey_number'])
        d['name'].append(rs['name_last_first'])


tabla = pd.DataFrame(d)
