Extended Statistics

Extended Statistics is a lightweight toolkit for comparing, profiling, and cleaning pandas DataFrames. It combines dataset diffing, an extended summary, and a handful of common cleaning transformations into a single, subpackage-organized API — built as a proof of concept for practicing Python package development fundamentals (structure, subpackages, testing, and packaging).

Features

• Dataset diffing: Compare two versions of a DataFrame and get a structured report of what changed: rows added/removed, columns added/removed, dtype changes, per-cell value changes (when a key column is provided), and shifts in summary statistics (mean/median/nulls) for numeric columns.
• Human-readable diff summaries: Turn a diff report into a plain-language sentence summary, no manual interpretation required.
• Dataset profiling: A single function that merges the useful parts of .describe() and .info() into one report: shape, memory usage, duplicate row count, and per-column stats (nulls, uniques, mean/median/std for numeric columns, top value/frequency for categorical columns).
• Basic cleaning utilities: Drop fully duplicate rows and standardize column names (lowercase, trimmed, underscore-separated) in one call each.
• Subpackage-organized API: Diffing, profiling, and cleaning each live in their own subpackage, with a top-level re-export layer so functions are accessible.
