pyxplr

pyxplr is a python package to make exploratory data analysis (EDA) simple and seamless. EDA is a crucial phase of the data science workflow as it allows us get a fist glimpse of the data. It is important to identify statistical characteristics of the data so that researchers can properly set up the rest of the analysis. This package will provide the tools required to conduct a thorough EDA.

Installation

# Install with dependencies
pip install --extra-index-url https://testpypi.python.org/pypi pyxplr

Functions

• explore_summary will display a table with basic summary statistics and wholistic information about the data including column names for both categorical and numerical columns.
• explore_outliers will provide outliers for each feature of data based on standard deviation.
• explore_missing will show exactly where there is missing data and how much data is missing.
• explore_feature_map will generate a faceted plot on pairwise feature relationships and correlations as well as individual feature distributions.

Python Ecosystem

This python package will build using the pandas and altair python packages that will help first time data science users more easily get started with their data projects. A similar package, pandas profiling is another EDA tool available. There are not many EDA packages that exist because both pandas and altair allow for full control of data wrangling and visualization, however users who are not experts with these packages will find pyxplr very useful.

Dependencies:

• pandas 1.0.1
• numpy 1.18.1
• altair 3.2.0

Usage:

import pyxplr
import vega_datasets

iris_df = vega_datasets.data.iris()

pyxplr.explore_summary(iris_df)
