Python: Built-in Functions vs. For & If Loops – 5 Programs Explained

-
Image
Python’s built-in functions make coding fast and efficient. But understanding how they work under the hood is crucial to mastering Python. This post shows five Python tasks, each implemented in two ways: Using built-in functions Using for loops and if statements ✅ 1. Sum of a List ✅ Using Built-in Function: numbers = [ 10 , 20 , 30 , 40 ] total = sum (numbers) print ( "Sum:" , total) 🔁 Using For Loop: numbers = [ 10 , 20 , 30 , 40 ] total = 0 for num in numbers: total += num print ( "Sum:" , total) ✅ 2. Find Maximum Value ✅ Using Built-in Function: values = [ 3 , 18 , 7 , 24 , 11 ] maximum = max (values) print ( "Max:" , maximum) 🔁 Using For and If: values = [ 3 , 18 , 7 , 24 , 11 ] maximum = values[ 0 ] for val in values: if val > maximum: maximum = val print ( "Max:" , maximum) ✅ 3. Count Vowels in a String ✅ Using Built-ins: text = "hello world" vowel_count = sum ( 1 for ch in text if ch i...

Dynamics of "Code Halos" in the age Digital world

[IoT -Code Halos Career]
[IoT -Code Halos Career]
“Code Halos – the information that surrounds people, organizations, and devices – are today's digital fuel. Every click, swipe, and view, every interaction and transaction generates a halo of code – a "virtual self" – that's robust, powerful, and rich with meaning and insight. You can go with an excellent book on Code halos.

Code Halos are a given in our personal lives; however, they are increasingly vital to every organization's future business success.” Research conducted by Cognizant's Center for the Future of Work reveals that organizations that create, share, and distill meaning from Code Halos are dominating their industries.
The dynamics of Code Halos is realized in our ever-increasing daily interactions across the web like social media, e-commerce, file sharing, smartphone apps, and other computing devices.

Moreover there are multiple layers of interdependencies between each of these interactions that create a unique virtual identity termed by Cognizant as Code Halos. Accordingly, it is a halo of digital information connecting people, organizations, processes, and devices.

Extending the Code Halos idea to other meaningful data at the enterprise level unravels some interesting examples: Insurance companies Allstate and Progressive and others are using very specific driver data, collected in many cases through telematics devices, to create new kinds of commercial models for personal and auto insurance.

Disney has created its MagicBand system where it has encoded user credit card information and what kind of things consumers are interested in; it helps users get a very personalized theme-park guest experience based on data and information, and it’s all encoded in a wristband. In manufacturing, GE creates code halos around their jet engine with hundreds of sensors built into the engine, generating data useful for GE and airlines. It’s lowering costs, improving safety, and efficiency, and there are many business benefits.

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...

5 SQL Queries That Popularly Used in Data Analysis

-
Image
 Here are five popular SQL queries frequently used in data analysis. 1. SELECT with Aggregations Summarize data by calculating aggregates like counts, sums, averages, etc. SELECT department, COUNT(*) as employee_count, AVG(salary) as average_salary FROM employees GROUP BY department; 2. JOIN Operations  Combine data from multiple tables based on a related column. SELECT e.employee_id, e.name, d.department_name FROM employees e JOIN departments d ON e.department_id = d.department_id; 3. WHERE Clause for Filtering Filter records based on specified conditions. SELECT * FROM sales WHERE sale_date BETWEEN '2024-01-01' AND '2024-12-31'   AND amount > 1000; 4. ORDER BY Clause for Sorting Sort results in ascending or descending order based on one or more columns. SELECT product_name, price FROM products ORDER BY price DESC; 5. GROUP BY with HAVING Clause Group records and apply conditions to the aggregated results. SELECT department, SUM(salary) as total_salaries FROM employ...
