When using findAll with BeautifulSoup it returns an empty list

Question

I'm practicing some web scraping and for this project I'm scraping this website: https://assetdash.com/?all=true

I'm getting and parsing the HTML code as following.

my_url = 'https://assetdash.com/?all=true'
client = urlopen(my_url)
page_html = client.read()
client.close()

soup = BeautifulSoup(page_html, 'html.parser')
rows = soup.findAll("tr", {"class":"Table__Tr-sc-1pfmqa-5 gNrtPb"})
print(len(rows))

This returns a length of 0 whereas it should be returning a much higher value. Have I done something wrong with the parsing or am I retrieving the rows incorrectly?

Answer 1

It dynamic and javascript rendered. Go straight to the source of the data.

Code:

import requests
my_url = 'https://assetdash.herokuapp.com/assets?currentPage=1&perPage=200&typesOfAssets[]=Stock&typesOfAssets[]=ETF&typesOfAssets[]=Cryptocurrency'

data = requests.get(my_url).json()
df = pd.DataFrame(data['data'])

Output:

print (df)
