Scraping from Web
- download rather than retrieve over and over again, for the fact that some data isn't going to change(history transaction, history flight dll)
- It could be that we make naive assumption that we only just post parameters as a related form for particular url.
- Turns out that is not be the case, in network tools, we have some additional parameter that we're trying to figure out
- This is where the meat of wrangling in data science comes from
