Check whether a string is valid JSON or not in Python
JSON is a text format used to exchange data easily between various computer programs. It has a specific format which Python can validate. In this article, we will consider a string and use the JSON module to validate if the string represents a valid JSON format or not. Using json.loads() Method The json module has a method called loads() that loads a valid JSON string to create a JSON object. We can use a try-except block to catch any parsing errors ? import json def is_valid_json(json_string): try: ...
Read MoreFind common elements in list of lists in Python
When working with nested lists, you may need to find elements that appear in all inner lists. Python provides several approaches to find common elements across multiple lists using set operations. Using map() and set.intersection() The most straightforward approach uses set intersection. We convert each inner list to a set and find their intersection ? nested_lists = [['Mon', 3, 'Tue', 7, 'Wed', 4], ['Thu', 5, 'Fri', 11, 'Tue', 7], ...
Read MoreHow to create a Drawing Effect Animation using CSS
CSS drawing effect animation creates visually appealing illustrations that appear to be drawn in real-time. This effect is achieved using SVG paths combined with CSS animations, particularly leveraging stroke-dasharray and stroke-dashoffset properties. Syntax .path { stroke-dasharray: length; stroke-dashoffset: length; animation: name duration timing-function fill-mode; } @keyframes name { to { stroke-dashoffset: 0; } } Method 1: Drawing Shape Animation The following example creates a heart ...
Read MoreConvert dictionary to list of tuples in Python
Converting from one collection type to another is very common in Python. Depending on the data processing needs we may have to convert the key-value pairs present in a dictionary to tuples in a list. In this article we will see the approaches to achieve this. Using Dictionary items() This is the most straightforward approach where we use list comprehension with the items() method to extract key-value pairs as tuples ? Example day_dict = {30: 'Mon', 11: 'Tue', 19: 'Fri'} # Given dictionary print("The given dictionary:", day_dict) # Using list comprehension with items() ...
Read MoreWhy do we use HTML code and CSS in sites?
In the digital landscape, websites play a crucial role in sharing information, connecting businesses with users, and providing interactive experiences. Behind every visually appealing and functional webpage lies a powerful duo − HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets). Together, HTML and CSS form the foundation of web development, providing the structure and styling needed for modern websites. The Role of HTML in Website Development HTML serves as the structural backbone of web content, providing the foundation for organizing information. Here are the key reasons why HTML is essential − Structure and Organization − ...
Read MoreCheck if two lists are identical in Python
In Python data analysis, we may come across situations when we need to compare two lists and find out if they are identical, meaning having the same elements regardless of order. Python provides several methods to achieve this comparison. Using Sorting Method The simplest approach is to sort both lists and then compare them for equality. This method works when you want to check if both lists contain the same elements ? days_a = ['Mon', 'Tue', 'Wed', 'Thu'] days_b = ['Mon', 'Wed', 'Tue', 'Thu'] # Given lists print("Given days_a:", days_a) print("Given days_b:", days_b) # ...
Read MoreWhich should I learn first: JavaScript or HTML/CSS?
When starting web development, choosing the right learning path is crucial for building a solid foundation. This guide explores whether to begin with HTML/CSS or JavaScript, helping you make an informed decision based on your goals. Understanding HTML & CSS HTML provides the structural foundation of web pages, defining content like headings, paragraphs, and links. CSS handles the visual presentation, controlling colors, layouts, fonts, and styling. Together, they create the visual web pages you see in browsers. Example: Basic HTML Structure with CSS .container { ...
Read MoreCheck if list is strictly increasing in Python
A strictly increasing list is one where each element is smaller than the next element. Python provides several approaches to check this condition using all() with zip(), comparison operators, or the itertools module. Using all() and zip() This approach compares each element with its next element using zip(). The all() function returns True only if all comparisons are True ? numbers = [11, 23, 42, 51, 67] print("Given list:", numbers) # Check if strictly increasing if all(i < j for i, j in zip(numbers, numbers[1:])): print("Yes, List is strictly increasing.") else: ...
Read MoreCheck if list is sorted or not in Python
Lists are the most widely used data collections in Python. We may come across situations when we need to know if the given list is already sorted or not. In this article we will see different approaches to achieve this. Using sorted() Function We can compare the original list with its sorted version using the sorted() function. If they are equal, the list is already sorted ? numbers = [11, 23, 42, 51, 67] print("Given list:", numbers) if numbers == sorted(numbers): print("Yes, List is sorted.") else: print("No, ...
Read MoreWhich is better, a website developed using HTML/CSS/JS or the one developed using WordPress?
When deciding between building a website with HTML/CSS/JS versus WordPress, the choice depends on your specific needs, technical expertise, and project requirements. Custom-coded websites offer complete control and flexibility, while WordPress provides a user-friendly platform with pre-built components for faster development. What is HTML/CSS/JS? HTML, CSS, and JavaScript are the core technologies for web development. HTML (HyperText Markup Language) structures content with elements like headings, paragraphs, and images. CSS (Cascading Style Sheets) handles the visual presentation − colors, fonts, layouts, and styling. JavaScript adds interactivity, animations, and dynamic functionality to web pages. Example: Simple HTML/CSS/JS Website ...
