baresql : playing SQL directly on Python datas
==============================================
baresql improves sql agility of python data science beginners by :
* allowing sql over python objects (list, ranges, ...) and SQL Tables,
* requiring no special module except : pandas.
Inspiration :
-------------
* pypi.python.org/pypi/pandasql : sqldf for pandas
* pypi.python.org/pypi/ipython-sql : sql magic in Ipython
Features
--------
* query lists , tuple, dictionnaries, dataframes
* result as a dataframe, list of records, or list
* basic Common Table Expression support on old python3.3- versions
Installation
------------
You can install, upgrade, uninstall sqlite_bro.py with these commands::
$ pip install baresql
$ pip install --upgrade baresql
$ pip uninstall baresql
or just launch it from IPython with %load https://raw.githubusercontent.com/stonebig/baresql/master/baresql/baresql.py
Basic Example
-------------
::
from __future__ import print_function, unicode_literals, division # if Python2.7
from baresql import baresql
bsql = baresql.baresql(keep_log = True )
bsqldf = lambda q: bsql.df(q, dict(globals(),**locals()))
users = ['Alexander', 'Bernard', 'Charly', 'Danielle', 'Esmeralda', 'Franz']
# We use the python 'users' list like a SQL table
sql = "select 'Welcome ! ' , c0 from users$$"
bsqldf(sql)
