Iterating Dict Items

Concepts covered: pyDictIterate

Dictionaries provide several methods for iteration: you can loop over just keys, just values, or key-value pairs together. Each approach is useful in different situations. Iterating Over Keys By default, iterating over a dictionary yields its keys: Iterating Over Values Iterating Key-Value Pairs Filtering Dict Entries Common patterns when working with dictionary iteration: Iterating Nested Dicts Real-world data often involves dictionaries containing other dictionaries. You can use nested loops to access all levels: Building Dicts from Loops You can construct dictionaries dynamically while iterating: When iterating over dictionaries, follow these practices to keep your code safe and readable: Dictionary views are live: if you add or remove keys after creating a view, the view reflects those

About This Interactive Section

This section is part of the Loops: 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.
