from pytrends.request import TrendReq
import requests
#make a pytrends object to request Google Trends data
pytrends = TrendReq(hl='en-US') 
#extract data about weekly searches of certain keywords
keywords = ["Python", "R", "C++", "Java", "HTML"]
pytrends.build_payload(keywords, timeframe='today 5-y')

and my error is
