I have been trying for hours to figure this out. From a building tutorial to just trying to find prebuilt ones, I can’t seem to make it click.
For context I am trying to scrape books myself that I can’t seem to find elsewhere so I can use and post them for others.
The scraper tutorial
Hackernoon tutorial by Ethan Jarell
I initially tried to follow this but I kept having a “couldn’t find module” error. Since I have never touched python prior to this, I am unaware how to fix this and the help links are not exactly helpful. If there’s someone who could guide me through this tutorial that would be great.
Selenium
I don’t really get what this is but I think its some sort of python pack and it tells me to download using the pip command but that doesn’t seem to work (syntax error). I don’t know how to manually add it in because, again, I have little idea of what I’m doing.
Scrapy
This one seemed like it’d be an out-of-box deal but not only does it need the pip command to download but it has like 5 other dependencies it needs to function which complicates it more for me.
I am not criticizing these wares, I am just asking for help and if someone could help with the simplification of it all or maybe even point me to an easier method that would be amazing!
Updates
- Figured out that I am supposed to run the command for pip in the command prompt thing on my computer, not the python runner.
py -mfollowed by the pip request
-
Got the Ethan Jarrell tutorial to work and managed to add in selenium, which made me realize that selenium isn’t really helpful with the project. rip xP

Spent a bunch of time trying to workshop the basic scraper to work with dynamic sites, unsuccessful

Online self-help doesn’t go in as much as I would like, probably due to the legal grey area
In my experience, this scenario typically means that there is some sort of API (very likely undocumented) that is being used on the backend. That requires a bit more investigation and testing with browser developer tools, the JS Console, and often trial and error. But once you overcome that (admittedly very complex and technical) hurdle, you can almost always get away with just using the requests library at that point.
I’ve had to do that kind of thing more times than I’d like to admit, but the juice is almost always worth the squeeze.
Well if I was doing it I probably would be trying to focus on browser emulation to avoid having to dig into those sorts of details. It sounds like OP is a beginner and needs a simple method.
I agree that OP sounds like a beginner, and what you’ve suggested is likely the best approach for someone who is familiar with frontend tools and frameworks. Selenium (and admittedly BeautifulSoup) is probably too low level for this particular user, but that doesn’t mean they can’t still learn some fundamentals while solving this problem without resorting to something as heavy and complicated as background browser emulation and rendering. I could be wrong though.
