-
Image
 Amazon Relational Database Service (AWS RDS) makes it easy to set up, operate, and scale a relational database in the cloud. Instead of managing servers, patching OS, and handling backups manually, AWS RDS takes care of the heavy lifting so you can focus on building applications and data pipelines. In this blog, we’ll walk through how to create an AWS RDS instance , key configuration choices, and best practices you should follow in real-world projects. What is AWS RDS? AWS RDS is a managed database service that supports popular relational engines such as: Amazon Aurora (MySQL / PostgreSQL compatible) MySQL PostgreSQL MariaDB Oracle SQL Server With RDS, AWS manages: Database provisioning Automated backups Software patching High availability (Multi-AZ) Monitoring and scaling Prerequisites Before creating an RDS instance, make sure you have: An active AWS account Proper IAM permissions (RDS, EC2, VPC) A basic understanding of: ...

4 Top Python Oops Concepts Simplify Your Coding

-
Oops concepts in Python explained in this post. Python supports Encapsulation, Inheritance, Abstraction, Polymorphism and Dynamic binding. These simplify your coding effort. I have given examples on Python Oops ( Object oriented) concepts.

python oops concepts

Python Oops (Object oriented) Concepts

  1. Encapsulation
  2. Data hiding and abstraction
  3. Inheritance
  4. Polymorphism (overloading/overriding)
The fifth Python special property is Dynamic binding.

#1 Python Oops Encapsulation

Wrapping of data and functions in a single unit is called Encapsulation.

Encapsulation

#2 Python Oops Data Hiding and abstraction

User program refers to methods from an object is called abstraction. Keeping all the methods under one object called data hiding.

Abstraction

#3 Python Oops Inheritance

Inhering properties means, referring property of an object of a class from an Object of the other Class.

Inheritance

#4 Python Oops Polymorphism

Poly means many. The definition of one function can use for many. 

The best example is the "+" operator. You can use it for the addition of numbers, and concatenate of String. 

Polymorphism

#5 Dynamic Binding

Dynamically you can call one procedure during the execution of the main program is called Dynamic binding. 

Dynamic Binding

Step-by-Step Guide to Reading Different Files in Python

-
Image
 In the world of data science, automation, and general programming, working with files is unavoidable. Whether you’re dealing with CSV reports, JSON APIs, Excel sheets, or text logs, Python provides rich and easy-to-use libraries for reading different file formats. In this guide, we’ll explore how to read different files in Python , with code examples and best practices. 1. Reading Text Files ( .txt ) Text files are the simplest form of files. Python’s built-in open() function handles them effortlessly. Example: # Open and read a text file with open ( "sample.txt" , "r" ) as file: content = file.read() print (content) Explanation: "r" mode means read . with open() automatically closes the file when done. Best Practice: Always use with to handle files to avoid memory leaks. 2. Reading CSV Files ( .csv ) CSV files are widely used for storing tabular data. Python has a built-in csv module and a powerful pandas library. Using cs...

SQL Query: 3 Methods for Calculating Cumulative SUM

-
Image
SQL provides various constructs for calculating cumulative sums, offering flexibility and efficiency in data analysis. In this article, we explore three distinct SQL queries that facilitate the computation of cumulative sums. Each query leverages different SQL constructs to achieve the desired outcome, catering to diverse analytical needs and preferences. Using Window Functions (e.g., PostgreSQL, SQL Server, Oracle) SELECT id, value, SUM(value) OVER (ORDER BY id) AS cumulative_sum  FROM your_table; This query uses the SUM() window function with the OVER clause to calculate the cumulative sum of the value column ordered by the id column. Using Subqueries (e.g., MySQL, SQLite): SELECT t1.id, t1.value, SUM(t2.value) AS cumulative_sum FROM your_table t1 JOIN your_table t2 ON t1.id >= t2.id GROUP BY t1.id, t1.value ORDER BY t1.id; This query uses a self-join to calculate the cumulative sum. It joins the table with itself, matching rows where the id in the first table is greater than...
