Print types of nested structues

Project description

This package helps describe complex, nested Python data structures. Use the prettytype function to print the structure and quickly understand what type of object you have.

Install with: pip install prettytype

For example, let’s examine a complex JSON object from the internet:

import requests
import json

r = requests.get('https://openlibrary.org/api/books?bibkeys=ISBN:0385472579,LCCN:62019420&format=json')
data = json.loads(r.text)
print 'Data:', data
print

from prettytype import prettytype
print 'Type:', prettytype(data)

===>

Data: {u'ISBN:0385472579': {u'bib_key': u'ISBN:0385472579', ......

Type: {str: {str: str}}

prettytype shows that the API returns nested dictionaries with string keys.
