Yin amfani da zaman Requests mai sanin wakili tare da pandas-datareader

pandas-datareader yana karɓar zaman Requests don aikinsa na HTTP. Misali, mai karanta FRED na iya amfani da zaman da aikace-aikacen ya saita:

import requests
from pandas_datareader import data as web

with requests.Session() as session:
    session.proxies.update({
        "http": "http://proxy.example.net:8080",
        "https": "http://proxy.example.net:8080",

Zaɓi mai karanta da sigar pandas-datareader da aka shigar ta goyi bayan. API na mai bayarwa da aka daina ko tsarin alama da aka canza na iya gazawa bayan haɗin wakili ya yi nasara; saita zaman ba ya dawo da ƙarshen bayanan da aka cire.
