Keyword Arguments

When calling a function, you can specify arguments by name instead of relying on position. This makes code clearer, especially for functions with many parameters or when the meaning of arguments is not obvious. Keyword arguments also let you skip optional parameters and provide only the ones you need. Positional vs Keyword Args You have been using positional arguments exclusively until now, where the order of values determines which parameter receives which value. Keyword arguments let you explicitly name the parameter you are providing a value for: Notice in the second example how the order of keyword arguments does not matter. Python matches them by name, not position. This flexibility is especially valuable when a function has many optional parameters with defaults. Why Use Keyword Argu

About This Interactive Section

This section is part of the Functional Programming: Intermediate lesson on DataDriven, a free data engineering interview prep platform. Each section includes explanations, worked examples, and hands-on code challenges that execute in real time. SQL queries run against a live PostgreSQL database. Python runs in a sandboxed Docker container. Data modeling problems validate against interactive schema canvases. All content is framed around what data engineering interviewers actually test at companies like Meta, Google, Amazon, Netflix, Stripe, and Databricks.

How DataDriven Lessons Work

DataDriven combines four interview rounds (SQL, Python, Data Modeling, Pipeline Architecture) with adaptive difficulty and spaced repetition. Easy problems get harder as you improve. Weak concepts resurface until you master them. Your readiness score tracks progress across every topic interviewers test. Every lesson section ends with problems you solve by writing and running real code, not by picking multiple-choice answers.
