Nothing beats the bar plot for fast data exploration and comparison of variable values between different groups, or building a story around how groups of data are composed. The ability to render a bar plot quickly and easily from data in Pandas DataFrames is a key skill for any data scientist working in Python.
In this tutorial, we’ll examine every aspect of creating bar charts with the Pandas library in Python.
Geocode your addresses for free with Python and Google For a recent project, I ported the “batch geocoding in R” script over to Python. The script allows geocoding of large numbers of string addresses to latitude and longitude values using the Google Maps Geocoding API. The Google Geocoding API is one of the most accurate geocoding …

Aggregation and data grouping of Dataframes is accomplished in Python Pandas using “groupby()” and “agg()” functions. In this post, we’ll look at every aspect of grouping by single or multiple columns, applying aggregation functions such as max, min, count, and naming the resulting Dataframes and Pandas Series.
As a practicing data scientist, I have regular need to present and distribute the results of analyses, or to provide descriptive statistics on data sets. Ideally these results can be presented in the form of interactive graphics, standalone applications, or as continually updating dashboards. There are a range of excellent dashboard and visualisation building softwares …
