如何从 python 的嵌套列表中提取文本并放入列中？

Question

This is the first observation. I need these all in different columns instead of the same column.

[{'route': 'Oral',
  'brand_name': 'MSK',
  'active_ingredients': [{'dose': {'denominator_unit': 'Unknown',
     'numerator': '1',
     'numerator_unit': 'Unknown',
     'denominator': '1'},
    'name': 'Diethylcarbamazine, Oxibendazole'}],
  'atc_vet_code': 'QP52AC57',
  'dosage_form': 'Tablet',
  'manufacturer': {'registration_number': 'USA-USFDACVM-N136483',
   'name': 'MSK'}}]

I want the result to look something like this.

route	brand name	active_ingredients	brand name	atc_vet_code	dosage_form'
oral	MSK	Diethylcarbamazine, Oxibendazole	QP52AC57	tablet

The relevant answer is the one talking about json_normalize . https://stackoverflow.com/a/53831756/381179

A list of nested dicts is pretty much what the json data format would look like, and rather than writing some custom read-in functionality, you can use what's already there
