The Pandas library is under constant development and new features are added regularly. This means that code you may read about online may not work if you are running an older version of Pandas. Similarly, some of Pandas’ dependencies - the other Python packages it uses internally - get upgraded and have different functionality.

In this quick and easy tutorial, I’ll show you how you can use the pd.__version__ dunder method and the pd.show_versions() method to view the current version of Pandas installed in your data science environment, as well as the names and version numbers for all the Pandas dependencies currently in use.

Use pd.__version__ to find the Pandas version

To get started, open a Jupyter notebook and import the Pandas library using the import pandas as pd naming convention. Once loaded, you can use the pd.__version__ dunder method (short for double underscore method) to find the version of Pandas loaded in your environment. I’m running version 1.5.2.

import pandas as pd

Use pd.show_versions() to find Pandas dependency versions

The pd.show_versions() method can be used to return some very useful information about your Python environment, including the architecture of your machine, the processor, language, operating system, and a full list of the Pandas package dependencies and their version numbers.

If you encounter a Pandas issue that needs to be raised with the Pandas development team, it’s a good idea to provide this with your bug report so they get a better understanding of the issue in order to attempt to replicate it.
