The pandas is a high-performance open source library for data analysis in Python developed by Wes McKinney in 2008. Over the years, it has become the de-facto standard library for data analysis using Python. There's been great adoption of the tool, a large community behind it, (220+ contributors and 9000+ commits by 03/2014), rapid iteration, features, and enhancements continuously made.
Some key features of pandas include the following:
- It can process a variety of data sets in different formats: time series, tabular heterogeneous, and matrix data.
- It facilitates loading/importing data from varied sources such as CSV and DB/SQL.
- It can handle a myriad of operations on data sets: subsetting, slicing, filtering, merging, groupBy, re-ordering, and re-shaping.
- It can deal with missing data according to rules defined by the user/developer: ignore, convert to 0, and so on.
- It can be used for parsing and munging (conversion) of data as well as modeling and statistical analysis.
- It integrates well with other Python libraries such as statsmodels, SciPy, and scikit-learn.
- It delivers fast performance and can be speeded up even more by making use of Cython (C extensions to Python).
