Read MorePython - Column summation of tuples
Python has extensive availability of various libraries and functions which make it so popular for data analysis. We may get a need to sum the values in a single column for a group of tuples for our analysis. So in this program we are adding all the values present at the same position or same column in a series of tuples. Column summation involves adding corresponding elements from tuples at the same positions. For example, if we have tuples (3, 92) and (25, 62), the column summation would be (28, 154). Using List Comprehension and zip() Using ...
Read MoreHow to define two column layout using flexbox?
To create a two column layout using flexbox can be so easy if you have the knowledge of CSS display property. Flexbox is a layout model in CSS that provides an efficient and flexible way to arrange and distribute space between items within a container. It arranges elements in a single dimension, either horizontally or vertically, within a container. To know more about the CSS Flexbox Layout visit the attached link. Imagine we have parent div and inside that div we have two child div all we have to do is place those child div side by horizontally. ...
Read Moremax() and min() in Python
Finding maximum and minimum values from a given list of values is a very common need in data processing programs. Python provides built-in max() and min() functions that handle both numbers and strings efficiently. Syntax max(iterable, *[, key, default]) min(iterable, *[, key, default]) Using max() and min() with Numeric Values Both functions work with integers, floats, and mixed numeric types to find the maximum and minimum values ? numbers = [10, 15, 25.5, 3, 2, 9/5, 40, 70] print("Maximum number is:", max(numbers)) print("Minimum number is:", min(numbers)) Maximum number is: ...
Read MoreHow to define the shape of the corners is animatable using CSS?
The CSS border-radius property can be animated to create smooth transitions between different corner shapes. This technique allows you to transform elements from sharp corners to rounded or circular shapes when users interact with them. Syntax selector { border-radius: initial-value; transition: border-radius duration; } selector:hover { border-radius: final-value; } Approach To create animatable corner shapes, follow these steps − Create an HTML element and assign it a class name Set the initial border-radius value (usually 0% for sharp corners) ...
Read MoreGetter and Setter in Python
In Python, getters and setters are methods used to control access to an object's attributes. They provide a way to implement data encapsulation, ensuring that attributes are accessed and modified in a controlled manner. Getters retrieve the value of an attribute, while setters allow you to modify it. This approach helps prevent direct manipulation of attributes from outside the class. Basic Class with Public Attributes Let's start with a simple class that has a public attribute − class YearGraduated: def __init__(self, year=0): self.year ...
Read MoreHow to define all the list properties in one declaration using CSS?
The CSS list-style property is a shorthand property that allows you to define all list-related styling in one declaration. This property combines list-style-type, list-style-position, and list-style-image into a single, convenient statement. Syntax selector { list-style: [type] [position] [image]; } Property Values ValueDescription list-style-typeSpecifies the type of list marker (disc, decimal, square, etc.) list-style-positionSpecifies marker position (inside or outside) list-style-imageSpecifies an image as the list marker Example 1: Basic List Styling The following example demonstrates how to style an unordered list with decimal markers positioned inside − ...
Read MoreFractal Trees in Python
Fractal patterns are everywhere in nature − a small branch resembles the entire tree, a fern leaf's part looks like the whole leaf. This self-repeating pattern concept is called a fractal tree. Python provides several modules to generate beautiful fractal trees programmatically. What is a Fractal Tree? A fractal tree is a mathematical structure that exhibits self-similarity at different scales. Each branch splits into smaller branches following the same pattern, creating a recursive tree-like structure. The recursion continues until reaching a specified depth. Using pygame Module The pygame module provides graphics functions to draw fractal trees. ...
