ClickHouse and Python: Jupyter Notebooks
Jupyter Notebooks are an indispensable tool for sharing code between users in Python data science. For those unfamiliar with them, notebooks are documents that contain runnable code snippets mixed with documentation. They can invoke Python libraries for numerical processing, machine learning, and visualization. The code output includes not just text output but also graphs from powerful libraries like matplotlib and seaborn. Notebooks are so ubiquitous that it’s hard to think of manipulating data in Python without them.
ClickHouse support for Jupyter Notebooks is excellent. I have spent the last several weeks playing around with Jupyter Notebooks using two community drivers: clickhouse-driver and clickhouse-sqlalchemy. The results are now published on Github at https://github.com/Altinity/clickhouse-python-examples. The remainder of this blog contains tips to help you integrate ClickHouse data to your notebooks.
