Right now I'm learning Bootstrap from your udemy bootstrap course. Man, it's amazing! it's not just videos or slides, it has a very comprehensive code examples which accompanies whatever Brad says in the video. Brad did a hell of a job in this course! It's wonderful! I highly recommend it. I've not tried other brad's udemy courses, but if they are as half good as his bootstrap course, I'm sold! This man is a god among us! Love you brad, the great instructor and the awesome family man! God bless you and your family.

for code 'page = response.url.split('/')[-1]'. I thought it should be page = response.url.split('/')[-2] and it works for me. But I donot know why it works with 'page = response.url.split('/')[-1]' in the vedio.

Nice and I know you've said there's lots more you could do with this, but one obvious improvement you could make to this is to collect an array or a set of URLs as you go to ensure you don't crawl the same page more than once - as I think that's what this code might end up doing, as it is right now. Right?

I may be mistaken but I believe there is already a default method named "parse" that is overwritten here. Nothing wrong with overwriting it but it could cause unexpected behavior for someone that doesn't know.

Hello! I want to do some web scraping but to find info on a certain thing. So normally, I would use a search engine to find the urls then from there, find the data I need. How would I automate the process of obtaining the URLS? The websites are pretty much the same ( I only really end up using 4 or 5 five websites with the data being a specific spot on the site). I would really appreciate any suggestions! Web scraping is such a good tool, but I need to automate the URL gathering process to accompany the Web scraping
