Specific steps:

parameters . update({ ' page ':pg _ no })

Pois.extend (data ['pois'])

no_pois_this_search = len(pois)

no_pois = int(data['count'])

7. Use pandas module to process data;

Df _ input = pd. data frames

8. Select the fields to output;

9. Use pandas module to output data, the file formats are tsv and json respectively, and the file name is "output" (which can be named by itself);
