No inicio do Curso Scraping Com Python: coleta de dados na web na célula 1.3 do Jupyter Notebook é pedido pra rodar esse código:
from urllib.request import urlopenfrom bs4 import BeautifulSoupurl='http://alura-site-scraping.herokuapp.com/hello-world.php' response=urlopen(url) html=response.read()
Ao tentar rodar aprece esse erro (O que faço pra resolver, isso?): (ACABO DE NOTAR TAMBÉM: por vezes não acontece nada. O compilador roda a célula, pula pra célula seguinte e nada aparece.)
