3.3.3 Iterating Over Dictionaries

Iterating over a dictionary allows a program to process each key, value, or pair.


Iteration Options

A dictionary can be iterated:

  • By keys
  • By values
  • By key–value pairs

Each approach is useful depending on the task.


Common Iteration Patterns

  • Looping through keys for lookups
  • Looping through values for analysis
  • Looping through items for full data processing

📌 Note:
Iterating over dictionaries is a common pattern in data processing and application logic.
