Using break and continue

Concepts covered: pyBreakContinue

The break Statement The continue Statement break vs continue Understanding the difference is crucial: break and continue in while These statements work the same way in while loops: Combining break with Flags Sometimes you need to know whether a loop exited normally or via break. A flag variable can track this distinction: The flag variable starts False and becomes True only if the target is found. After the loop, you check the flag to determine the outcome. This pattern is useful when you need different behavior based on whether the search succeeded. Nested Loops and break

About This Interactive Section

This section is part of the Loops: Beginner 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.
