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.
