What are some examples of the Strategy Pattern in Python?

Can you explain the Strategy Pattern in Python?

Sure! The Strategy Pattern is a behavioral design pattern that enables selecting an algorithm's behavior at runtime.

Can you give me a practical example of it?

Absolutely! Imagine you have a sorting application. You can use different sorting strategies like QuickSort or MergeSort.

How would I implement that in Python?

You would define a common interface for sorting strategies, then create classes for each sorting algorithm that implement this interface.

Can you show me some code for that?

Sure! Here's a simple implementation:

class SortStrategy:
    def sort(self, data):
        pass

class QuickSort(SortStrategy):
    def sort(self, data):
        # QuickSort implementation
        return sorted(data)

class MergeSort(SortStrategy):
    def sort(self, data):
        # MergeSort implementation
        return sorted(data)

class Context:
    def __init__(self, strategy: SortStrategy):
        self.strategy = strategy

    def execute_sort(self, data):
        return self.strategy.sort(data)

You can then switch strategies at runtime!
