Big Data

In this tutorial, we construct a complete, hands-on understanding of DuckDB-Python by working by means of its options immediately in code on Colab. We begin with the basics of connection administration and information technology, then transfer into actual analytical workflows, together with querying Pandas, Polars, and Arrow objects with out handbook loading, reworking outcomes throughout…

In this tutorial, we build a complete pipeline for single-cell RNA sequencing analysis using Scanpy. We start by installing the required libraries and loading the PBMC 3k dataset, then perform quality control, filtering, and normalization to prepare the data for downstream analysis. We then identify highly variable genes, perform PCA for dimensionality reduction, and construct…

In this tutorial, we demonstrate how we use Ibis to build a portable, in-database feature engineering pipeline that looks and feels like Pandas but executes entirely inside the database. We show how we connect to DuckDB, register data safely inside the backend, and define complex transformations using window functions and aggregations without ever pulling raw…

In this tutorial, we construct a complicated interactive dashboard utilizing Textual, and we discover how terminal-first UI frameworks can really feel as expressive and dynamic as fashionable net dashboards. As we write and run every snippet, we actively assemble the interface piece by piece, widgets, layouts, reactive state, and occasion flows, so we will see…
