Beautiful Soup: How to get timestamp inside td - beautifulsoup

Question

How do I get the value from 'data-timestamp' and convert it into an integer using BeautifulSoup. I'm iterating through each row on a website (which is a tr class).
So if i were to set up the code as
ratings = []
rows = soup.select('tbody tr')
for row in rows:
'insert code here'
ratings.append(rating)
However, I can't seem to access the value in the data-timestamp. I've tried using attrs but I'm assuming I'm doing it wrong. Any help would be much appreciated.
<td data-timestamp="4.5833333333333" class="hide-on-hover fill-space relative">
<div class="col border-box text-center nowrap row large-up-text-right padding-horz-small push">```

Answer 1

This should give you the string value:
[...]
for row in rows:
data_timestamp_str = row.find("td")['data-timestamp']
[...]
You can convert the string to an integer with int(data_timestamp_str), but note that in your example data this wouldn't work, because the value of data-timestamp is 4.583333333333, which is not an integer.

Answer 2

Access the tag using [], then round it to two decimal points, for example:
from bs4 import BeautifulSoup
html_doc = """<td data-timestamp="4.5833333333333" class="hide-on-hover fill-space relative">
<div class="col border-box text-center nowrap row large-up-text-right padding-horz-small push">```"""
soup = BeautifulSoup(html_doc, 'html.parser')
ratings = []
rows = soup.select('td')
for row in rows:
ratings.append(round(float(soup.select_one('td')['data-timestamp']), 2))
print(*ratings)
Outputs:
4.58
