python - Sensible way to create filenames for files based on URLs? -


i screenshotting bunch of web pages, using python selenium. want save pngs locally reference. list of urls looks this:

www.mysite.com/dir1/pagea www.mysite.com/dir1/pageb

my question filenames give screenshotted pngs.

if call image files e.g. www.mysite.com/dir1/pagea.png meaningless slashes inevitably cause problems @ point.

i replace / characters in url _, suspect might cause problems too, e.g. if there _ characters in url. (i don't strictly need able work backwards filename url, wouldn't bad thing.)

what's sensible way handle naming?

the easiest way represent what's directory structure on server wget , replicate structure on local machine.

thus / characters become directory delimiters, , www.mysite.com/dir1/pagea.png become png file called pagea.png in directory called dir1, , dir1 located in directory called www.mysite.com.

it's simple, guaranteed reversible, , doesn't risk ambiguous results.

This guest post is by Phil (not his real name) of somehighschoolblog . It used to be impossible to run a business anonymously. Sure, some authors could pull it off, but if you worked at an office, what were you supposed to do? Go to work with a bag over your head? But today anyone can accomplish this, because anyone can author a blog (and you thought I was going to tell you to work with a mask on, or something).
