How to parse with python requests?

Question

Parsing

Everyone knows perfectly well the main library for parsing in python, these are requests. So the question arose, I need to access the site every 5-7 seconds, it is obvious that the site will perceive such frequent requests as ddos ​​and restrict access to the site. Is it possible, for example, to open the site once and constantly read information from it, so as not to establish a connection every 5 seconds? I tried to access the site from Tor, a captcha arrives immediately, that is, not an option, TorCrawler is also by (the same Tor, only a little on the side).

Answer 1

1) 5-7 seconds is a lot, so this is not a ddos ​​attack. Many commercial companies that scrape websites (including mvideo, ozone and other stores) scrap one product every 5-7 seconds.
2)

Is it possible, for example, to open the site once and constantly read information from it, so as not to establish a connection every 5 seconds?

There is, if only the site gives information via websocket (not encrypted).
3) Either load the page every 5-7 seconds, or you can look in devtools, maybe the site gives information via xhr request. In this case, it might be easier to parse.
