Decorators are functions that modify the behavior of other functions without changing their source code.
Decorators are denoted by the '@' symbol followed by the decorator function name.
They can be used to add functionality to a function, such as logging or timing.
Decorators can also be used to modify the behavior of a class or method.
They are commonly used in web frameworks like Flask and Django.

Namespace is a container that holds identifiers (names) used to avoid naming conflicts.
Namespace is created at different moments and has different lifetimes.
Python implements namespaces as dictionaries.
There are four types of namespaces in Python: built-in, global, local, and non-local.
Namespaces can be accessed using the dot (.) operator.
Example: 'import math' creates a namespace 'math' that contains all the functions
Algorithm to solve Sudoku puzzle
Create a 9x9 grid to represent the puzzle
Fill in known numbers
For each empty cell, try numbers 1-9 until a valid number is found
Backtrack if no valid number can be found
Repeat until all cells are filled

A decorator is a design pattern in Python that allows adding new functionality to an existing object without modifying its structure.
Decorators are denoted by the @ symbol followed by the decorator function name.
They are commonly used to modify or extend the behavior of functions or methods.
Decorators can be used for logging, timing, authentication, caching, etc.
Example: @staticmethod, @classmethod, @property

Simple python programming concepts
Inter service communication in transactional systems involves designing a reliable and efficient way for services to communicate and exchange data.
Use asynchronous messaging systems like RabbitMQ or Kafka to decouple services and ensure reliable message delivery.
Implement RESTful APIs for synchronous communication between services, using HTTP methods like GET, POST, PUT, DELETE.
Consider using gRPC for high-performance,...
Use pandas library for efficient loading and processing of large files in Python.
Use pandas read_csv() function with chunksize parameter to load large files in chunks.
Optimize memory usage by specifying data types for columns in read_csv() function.
Use pandas DataFrame methods like groupby(), merge(), and apply() for efficient data processing.
Consider using Dask library for parallel processing of large datasets.
Use gen...
