Feature Engineering in Python Cheatsheet

Models expect a clean numeric matrix and raw data never arrives as one; feature engineering is the bridge. This cheatsheet gathers the whole toolkit on one page, from encoding and binning through scaling, outliers, and TF-IDF, to the fit-on-train rule that keeps every score honest, each snippet annotated line by line. Keep it open while you work, or save the image and pin it nearby.

For the full background, read the guide to feature engineering in Python. To practise, work through the 10 code-along examples.
