Beautifulsoup : Is there a difference between .find() and .select() - python 3.xx

Best

I've a simple question :

when you use Beautiful Soup to scrape a certain part of a website, you can use data.find() / data.findAll() or data.select()

Now the question is. Is there a significant difference between the .find() and the .select() methodes? (e.g. in performance or flexibility, or ...)

or are they just the same?

Kind regards
