    List of must known useful libraries in python

requests (http client for humans)
mysqlclient (using mysql)
attrdict (dict as object and object as dict)

requests

Probably the most famous http client for python.
Project page: http://docs.python-requests.org/en/master/
Installation

pip install requests
Example

>>> r = requests.get('https://api.github.com/user', auth=('user', 'pass'))
>>> r.status_code
200
>>> r.headers['content-type']
'application/json; charset=utf8'
>>> r.encoding
'utf-8'
>>> r.text
u'{"type":"User"...'
>>> r.json()
{u'private_gists': 419, u'total_private_repos': 77, ...}
mysqlclient

The common mysql binding for python.
Project page:
Installation

Python developpement files and mysql connectors (a bit painful under windows)
Ubuntu dependencies:
sudo apt-get install python-dev libmysqlclient-dev
Install from PyPi
pip install mysqclient
Example

import MySQLdb
db=MySQLdb.connect(passwd="moonpie",db="thangs")
c=db.cursor()
max_price=5
c.execute("""SELECT spam, eggs, sausage FROM breakfast
          WHERE price < %s""", (max_price,))
# fetchone(), fetchall(), fetchmany(n)
c.fetchone()  # returns tuple (3L, 2L, 0L)
using db.cursor(MySQLdb.cursors.DictCursor) instead of db.cursor() will get you result as dict() instead of tuple which is awesome. If you want more, read the doc: https://mysqlclient.readthedocs.io/en/latest/
attrdict

Dictionnaries as objects with attributes. Useful for results of API call or SELECT in Database.
GitHub page: https://github.com/bcj/AttrDict
Installation

pip install attrdict
Example

>>> from attrdict import AttrDict
>>> a = AttrDict({'foo': 'bar'})
>>> a.foo
'bar'
>>>> a['foo']
'bar'
