The below code returns me a table with the following results

r = requests.get(url)
soup = bs4.BeautifulSoup(r.text, 'lxml')mylist = soup.find(attrs={'class': 'table_grey_border'})
print(mylist)

results - it stretches on for 1700 rows

My question is, how do I put each of these rows into Pandas Dataframe? I tried the below code, but i'm returned with an error

a = pandas.read_html(mylist)
print(a)

error

TypeError: 'NoneType' object is not callable

Document:

pandas.read_html(url, attrs={'class': 'table_grey_border'})
