Python Algo Set 1

Description:

This collection of Python scripts showcases a variety of algorithms and data structures, focusing on practical implementations and problem-solving techniques. Each script is designed to address specific programming challenges, making them valuable resources for both learning and reference.

1. 2d_lists.py

The 2d_lists.py script demonstrates the creation and manipulation of two-dimensional lists (arrays) in Python. It includes functions for ordering elements and resizing the lists, providing insights into how to effectively manage and utilize 2D data structures for various applications.

2. backtracking.py

This script implements backtracking algorithms, a powerful technique used for solving constraint satisfaction problems. It serves as a foundational example for understanding how to explore potential solutions and backtrack when a solution path fails.

3. case_sort.py

The case_sort.py script focuses on sorting strings while preserving their original case. It utilizes Python's built-in sorting capabilities, demonstrating how to use custom keys for sorting operations, which is essential for handling text data effectively.

4. chain_map.py

This script introduces the concept of ChainMap, a class that groups multiple dictionaries into a single view. It is useful for managing multiple contexts and provides a way to access variables from different scopes seamlessly.

5. class_methods.py

The class_methods.py script explores the use of class methods in Python. It includes examples of how to refactor code to utilize class methods effectively, enhancing code organization and readability.

6. counter_demo.py

This script demonstrates the use of the Counter class from the collections module. It showcases methods for counting occurrences of elements, subtracting counts, and retrieving the most common elements, making it a practical tool for data analysis.

7. decimal_demo.py

The decimal_demo.py script illustrates the use of the Decimal class for precise decimal arithmetic. It highlights the importance of precision in financial calculations and provides examples of how to work with decimal numbers in Python.

8. deque_demo.py

This script introduces the deque (double-ended queue) data structure from the collections module. It demonstrates how to use deque for efficient appending and popping of elements from both ends, making it suitable for queue implementations.

9. factorial.py

The factorial.py script provides a straightforward implementation of the factorial function, including a base case for recursion. It serves as an introduction to recursive programming and mathematical computations in Python.

10. word_count.py

This script counts the occurrences of words in a given text file. It demonstrates file handling, string manipulation, and the use of dictionaries for counting, making it a practical example for text processing tasks.
