Counting With Python's Counter (Summary)

When you need to count several repeated objects in Python, you can use Counter from collections. This class provides an efficient and Pythonic way to count things without the need for using traditional techniques involving loops and nested data structures. This can make your code cleaner and faster.

In this video course, you learned how to:

• Count several repeated objects using different Python tools
• Create quick and efficient counters with Python’s Counter
• Retrieve the most common objects in a particular counter
• Update and manipulate object counts
• Use Counter to facilitate further computations
• Implement Counter instances as multisets
