从 JSON 文件中提取特定数据

Question

I have this json file that is available in the link https://raw.githubusercontent.com/Cyral/Bakeoof/master/full_format_recipes.json

and I used Pandas to open the recipes JSON file.

import pandas as pd
df = pd.read_json('full_format_recipes.json', lines=True)
print(df)

and this is the output I get

[1 rows x 20130 columns]

I want to extract only the directions and the title for each recipe, How can I do that?

Answer 1

Remove lines=True - that's meant for JSON files in which an object exists on each line, or if you want to read in each object individually. That is, with line=True although each object has the same properties, they are not collated into a single entity.

Making that modification, you'll be able to access the properties you desire:

import pandas as pd
url = 'https://raw.githubusercontent.com/Cyral/Bakeoof/master/full_format_recipes.json'
df = pd.read_json(url)
print(df['directions'])
print(df['title'])

Ref: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.read_json.html

Answer 2

If you get rid of lines=True it should format your code accordingly to allow you to access your JSON as you normally would. You don't need it in that structure.
