Keywords: data pandas aggregation

pandas\_lite
============

A simpler alternative to pandas

Main Goals
==========

-  A very minimal set of features
-  Be as explicit as possible
-  There should be one-- and preferably only one --obvious way to do it.

Data Structures
~~~~~~~~~~~~~~~

-  Only DataFrames
-  No Series

Data Types
~~~~~~~~~~

-  Only primitive types - int, float, boolean, numpy.unicode
-  No object data types

Row and Column Labels
~~~~~~~~~~~~~~~~~~~~~

-  No index, meaning no row labels
-  No hierarchical index
-  Column names must be strings
-  Column names must be unique
-  Columns stored in a numpy array

Subset Selection
~~~~~~~~~~~~~~~~

-  Only one way to select data - ``[ ]``
-  Subset selection will be explicit and necessitate both rows and
   columns
-  Rows will be selected only by integer location
-  Columns will be selected by either label or integer location. Since
   columns must be strings, this will not be amibguous
-  Column names cannot be duplicated

All selections and operations copy
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

-  All selections and operations provide new copies of the data
-  This will avoid any chained indexing confusion

Development
~~~~~~~~~~~

-  Must use type hints
-  Must use 3.6 - fstrings
-  Must have numpy, bottleneck, numexpr

Small feature set
~~~~~~~~~~~~~~~~~

-  Implement as few attributes and methods as possible
-  Focus on good idiomatic cookbook examples for doing more complex
   tasks

Only Scalar Data Types
~~~~~~~~~~~~~~~~~~~~~~

No complex Python data types - [x] bool - always 8 bits, not-null - [x]
int - always 64 bits, not-null - [x] float - always 64 bits, nulls
allowed - [x] str - A python unicode object, nulls allowed - [ ]
categorical - [ ] datetime - [ ] timedelta

Attributes to implement
^^^^^^^^^^^^^^^^^^^^^^^

-  [x] size
-  [x] shape
-  [x] values
-  [x] dtypes

May not implement any of the binary operators as methods (add, sub, mul,
etc...)
