A  set  in Python is an unordered collection of unique elements. It is useful when storing distinct values and performing operations like union, intersection, or difference. Real-Time Example: Removing Duplicate Customer Emails in a Marketing Campaign Imagine you are working on an email marketing campaign for your company. You have a list of customer emails, but some are duplicated. Using a set , you can remove duplicates efficiently before sending emails. Code Example: # List of customer emails (some duplicates) customer_emails = [ "alice@example.com" , "bob@example.com" , "charlie@example.com" , "alice@example.com" , "david@example.com" , "bob@example.com" ] # Convert list to a set to remove duplicates unique_emails = set (customer_emails) # Convert back to a list (if needed) unique_email_list = list (unique_emails) # Print the unique emails print ( "Unique customer emails:" , unique_email_list) Ou...

Today I woke up after my night sleep, and quickly I completed my daily routines. I thought a few minutes to write useful posts for my readers. I decided to write the differences between JavaScript and JSON.

JSON Quick Insights

  1. JSON is simply a data-interchange format and, therefore, does not directly require the immediate knowledge of the JavaScript language.
  2. JSON a subset of the JavaScript language.
  3. Data exchange can occur between both browser and server and even server to server.
  4. The file extension is .json.
  5. You can structure the JSON as below:
  6. A collection of name/value pairs.
  7. An ordered list of values.
  8. An introduction to JSON read here


JavaScript Quick Insights

  • JavaScript is a text-based scripting language, whereby sequences of Unicode characters strung together.
  • JavaScript supports two different types of data types.
  • Primitive and non-primitive. Primitive data types the best example is the Object. The non-primitive examples are number, string, Boolean, undefined, and null.
  • A semicolon is the line terminator in JavaScript.
  • The top control statements it supports are IF, ELSE, and FOR-loop.
  • The file extension is .js.
  • An introduction to JavaScript tread here.

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...
