Iterating Dict Items

Concepts: 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
