Guys, I need some help with the code on Python searching results of the internet.

Python 3.6

The first of Bitcoin worked out, the second that presents error.

from urllib import request

url = request.urlopen("https://dolarhoje.com/bitcoin-hoje/").read()
url = str(url)
find = '<input type="text" id="nacional" value="'
posicao = int(url.index(find) + len(find))

BitCoin = url[ posicao : posicao + 8 ]
print("Valor BitCoin Hoje: "+ BitCoin + " R$")

url2 = request.urlopen("https://www.ativo.com/calendario/inscricoes/america-do-sul/br/mg/belo-horizonte/corrida-de-rua/36044/park-run-2019").read()
url2 = str(url2)
find = '<div class="row_header titulo_evento"'
posicao1 = int(url2.index(find) + len(find))

Running = url2[posicao1 : posicao1 + 4]
print("Corrida BH:  2019"  + Running)

Upshot:

/usr/bin/python3.6 /home/system/Documents/Labs/Python/CrawlerPy/Crawler.py 
Valor BitCoin Hoje: 15186,97 R$ 
Traceback (most recent call last): File "/home/system/Documents/Labs/Python/CrawlerPy/Crawler.py", line 14, in <module> posicao1 = url2.index(find) + len(find) 
ValueError: substring not found Process finished with exit code 1

I think code url2.index(find) you’re not finding anything.

*Knowing that find = '<div class="row_header titulo_evento"'

I paid a quick visit to website and I tried to find that element and I couldn’t find it.

Besides looking at the answer of the site you can also use the Javascript command to try to find this element $('div.row_header.titulo_evento').length
