Python - Scrape Javascript using bs4 and print out the value

So I have been trying to create a script where there is a countdown with epoch time which I later gonna convert it.

The html is following:

<script type="text/javascript">
                new Countdown('countdown_timer', '1547161260', 'https://stackoverflow.com/');
            </script>

and I started to scrape it which I managed to scrape using: 

try:
    time_countdown_tag = bs4.find_all('script', {'type': 'text/javascript'})
except Exception:
    time_countdown_tag = []

for countdown in time_countdown_tag:
    if 'new Countdown' in countdown.text.strip():
        print(countdown)

which my output is:

<script type="text/javascript">
                new Countdown('countdown_timer', '1547161260', 'https://stackoverflow.com/');
            </script>

However what I want to print out in this case is the number inside the params which is 1547161260 - I would appreciate all kind of help to be able to be able to only print out the number (epoch) if it is possible?

You can use regular expressions to match the portion of the JS that contains a positive integer:

import re
output = """<script type="text/javascript">
                new Countdown('countdown_timer', '1547161260', 'https://stackoverflow.com/');
            </script>"""
re.findall("\d+", output)
