Pretty Code

  • Syntax highlighting works in revealjs slides
  • Code uses the theme’s Courier stack
import polars as pl


def summarize_ridership(stations: pl.DataFrame) -> pl.DataFrame:
    return (
        stations
        .group_by("line")
        .len(name="station_count")
        .sort("station_count", descending=True)
    )

Line Highlighting

import numpy as np
import polars as pl

stations = pl.read_csv("cta_stations.csv")
orange = stations.filter(pl.col("line") == "Orange")

by_access = orange.group_by("accessible").len(name="station_count")
share = np.round(
    by_access["station_count"] / by_access["station_count"].sum(),
    2,
)

print(by_access.with_columns(accessible_share=share))

Column Layout

Course Pattern

  • Ask a data question
  • Find the relevant table
  • Check the units
  • Make a readable view
