Python pprint Exercise - Get project information limiting the results to a certain level
Python pprint: Exercise-6 with Solution
Write a Python program to fetch information about a project (i.e. PyPI) using pprint() function. Limit the result to a certain level and specify the width of the content.
Sample Solution:
Python Code:
import json
import pprint
from urllib.request import urlopen
with urlopen('https://pypi.org/pypi/aioxmpp/json') as resp:
project_info = json.load(resp)['info']
pprint.pprint(project_info, depth = 1, width = 160)
Sample Output:

'Features\n'
'========\n'
'\n'
'* Native `Stream Management (XEP-0198)\n'
' <https://xmpp.org/extensions/xep-0198.html>`_ support for robustness against\n'
' transient network failures (such as switching between wireless and wired\n'
' networks).\n'
'\n'
'* Powerful declarative-style definition of XEP-based and custom protocols. Most\n'
' of the time, you will not get in contact with raw XML or character data, even\n'
' when implementing a new protocol.\n'
'\n'
'* Secure by default: TLS is required by default, as well as certificate\n'
' validation. Certificate or public key pinning can be used, if needed.\n'
'\n'
'* Support for `RFC 6121 (Instant Messaging and Presence)\n'
' <https://tools.ietf.org/html/rfc6121>`_ roster and presence management, along\n'
' with `XEP-0045 (Multi-User Chats)\n'
' <https://xmpp.org/extensions/xep-0045.html>`_ for your human-to-human needs.\n'
'\n'
'* Support for `XEP-0060 (Publish-Subscribe)\n'
' <https://xmpp.org/extensions/xep-0060.html>`_ and `XEP-0050 (Ad-Hoc Commands)\n'
' <https://xmpp.org/extensions/xep-0050.html>`_ for your machine-to-machine\n'
' needs.\n'
'\n'
'* Several other XEPs, such as `XEP-0115\n'
' <https://xmpp.org/extensions/xep-0115.html>`_ (including native support for\n'
' the reading and writing the `capsdb <https://github.com/xnyhps/capsdb>`_) and\n'
' `XEP-0131 <https://xmpp.org/extensions/xep-0131.html>`_.\n'
'\n'
'* APIs suitable for both one-shot scripts and long-running multi-account\n'
' clients.\n'
'\n'
'* Well-tested and modular codebase: aioxmpp is developed in test-driven\n'
' style and in addition to that, many modules are automatedly tested against\n'
' `Prosody <https://prosody.im/>`_ and `ejabberd <https://www.ejabberd.im/>`_,\n'
' two popular XMPP servers.\n'
'\n'
'\n'
'There is more and there’s yet more to come! Check out the list of supported XEPs\n'
'in the `official documentation`_ and `open GitHub issues tagged as enhancement\n'
'<https://github.com/horazont/aioxmpp/issues?q=is%3Aissue+is%3Aopen+label%3Aenhancement>`_\n'
