In some cases it is possible to download only with pandas command:
pd.read_html(url)
If the command returns with the html response "forbidden" we can use the requests library, sending some header information to prevent this error.
import requests
import pandas as pd
url = r'https://www.worldometers.info/world-population/population-by-country/'
header = {
"User-Agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.75 Safari/537.36",
"X-Requested-With": "XMLHttpRequest"
}
r = requests.get(url, headers=header)
#world population - first table of the website
dfpop=pd.read_html(r.text)[0]
