Trying to scrape a specific table but getting no results

Question

I tried three different techniques to scrape a table named ‘table-light’, but nothing is actually working for me. The code below shows my attempts to extract the data.

import pandas as pd
tables = pd.read_html('https://finviz.com/groups.ashx?g=industry&v=120&o=marketcap')
tables


############################################################################


import requests
import pandas as pd
url = 'https://finviz.com/groups.ashx?g=industry&v=120&o=marketcap'
html = requests.get(url).content
df_list = pd.read_html(html)
df = df_list[10]
print(df)


############################################################################


import requests
from bs4 import BeautifulSoup
url = "https://finviz.com/groups.ashx?g=industry&v=120&o=marketcap"
r = requests.get(url)
html = r.text
soup = BeautifulSoup(html, "html.parser")
table = soup.find_all('table-light')
print(table)

The table that I am trying to extract data from is named ‘table-light’. I want to get all the columns and all 144 rows. How can I do that?

You can try to set User-Agent header to get the correct HTML (and not captcha page):

import pandas as pd
import requests
from bs4 import BeautifulSoup

url = "https://finviz.com/groups.ashx?g=industry&v=120&o=marketcap"

headers = {
    "User-Agent": "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:108.0) Gecko/20100101 Firefox/108.0"
}
soup = BeautifulSoup(requests.get(url, headers=headers).content, "lxml") # <-- don't use html.parser here

table = soup.select_one(".table-light")
for td in table.tr.select('td'):
    td.name = 'th'

df = pd.read_html(str(table))[0]
print(df.head())

Prints:
