We can understand the basic difference from their definitions. The answer to the second question is a bit tough, because there are lots of methods to get data. In basic, we could get knowledge from a database or data file and different sources. But what if we’d like great amount of data that is obtainable on-line? One method to get such sort of information is to manually search and save (copy-pasting right into a spreadsheet or file) the required data.
Similarly we will download the raw string response and by using python’s json.hundreds technique, we will load it too. It will basically scrape all of the international locations by looking the letter of the alphabet ‘a’ after which iterating the resulting pages of the JSON responses.
