问题
Many people in my company (and online) seem to use the words "scrape" and "scrap", as well as "scraping" and "scrapping" to refer to collecting data from a website/websites, to be used for various purposes.
I can't tell whether there is some nuance between the two uses, or whether the uses are completely interchangeable. I've searched around online, but haven't found a clear answer.
Is "web scrapping" an actual thing?
Does it have a distinct meaning from "web scraping"?
Is it simply a typo that has taken over, like "for all intensive purposes"?
回答1:
"Scrapping" is fighting or throwing something out, typically something that's reached end of life. "Scraping" is the correct term. If anyone's calling it "scrapping" they're just using an unfortunately common mis-spelling.
If you're feeling vigilant you might want to correct this any place you find it if it doesn't break a lot of code.

They are two different words. One comes from "scrap" (a noun: a leftover piece of something). The other comes from scrape (a verb: to rub, rake, or scratch something, usually with an instrument.)
