For example in python we write this code like this:

url = 'github.com/ headers = {'Referer':'github.com/example','User-Agent':'example'} #for User agent example you can check https://myhttpheader.com/ to see a User agent example is like what r = requests.get(url,headers = headers)

I saw a tutorial video that said User Agent is first and the Referer is second when you want to scrap a website. I mean websites want to prevent scraping through headers but these are the most important one according to my teacher teaching.

I want to be sure that if there is another header or another header with more accurate prioritization.
if you know one more header but you are not sure please sure with me.
