Parsing XML and counting instances of a particular node attribute in Python can be achieved through various methods. XML is a widely used format for storing and exchanging structured data. Python provides several libraries and approaches for parsing XML, including ElementTree, lxml, and xml.etree.ElementTree. In this article, we will learn how to parse XML and count instances of a particular node attribute in Python. We will cover different approaches using the available XML parsing libraries and demonstrate practical examples. By the end of this article, you will have a solid understanding of how to parse XML and count instances ... Read More
Parsing local HTML files in Python is a common task when dealing with web scraping, data analysis, and automation. In this article, we will learn how to parse local HTML files in Python. We will explore various techniques to extract data from an HTML file using Python. We will cover modifying and removing elements from the file, printing data, using recursive child generators to traverse the file's structure, finding tag children, and even web scraping by extracting information from a given link. Through code examples and syntax, we will demonstrate how to leverage Python libraries such as BeautifulSoup and ... Read More
When working with large datasets, one common PySpark operation is to order a DataFrame by multiple columns. You can prioritize the sorting based on various criteria when you sort data based on multiple columns. Using PySpark, we'll look at a few different approaches in this article. In this article, we will learn How to Order PysPark DataFrame by Multiple Columns. PySpark provides several methods to order DataFrames where each method offers different features and performance characteristics, so let's dive into each one and understand how to use them. Different Method to Order PysPark DataFrame by Multiple Columns There are various ... Read More
Pygame is a powerful library that allows developers to create engaging 2D games using the Python programming language. One fundamental aspect of game development is character movement.

A binary string is a type of string which contains only binary characters that are '0' and '1'. We are given a binary string and have to find the triplets that fulfill the condition that the bitwise 'AND' of the first two characters is equal to the bitwise 'AND' of the last two characters. Mathematically: For 0
A linked list is a linear data structure that stores the data in the nodes and each node contains the address of the next node to make the connection. A peak or the peak node is the node that is not present at the first or the last place and has a value strictly greater than both of the neighbors. We have to find the maximum distance between two consecutive peaks as there could be more than one peak available. Sample Examples Input Given Linked list: 1 -> 2 -> 3 -> 2 -> 7 -> 1 ... Read More
Right Rotations means we have to shift each element towards the right as the 0th index element shift to the 1st index, the 1st index element shift to the 2nd index, ..., and the last element shift to the 0th index. Here we have given an array of integers of size n, integer m, and integer k. Our task is to find the mth element after k right rotations of an array. Here are some examples and explanations to help you understand the issue. Sample Examples Input Array: [ 1, 3, 2, 5, 6, 7 ], k: ... Read More
A number is strictly a smaller element means the number should be less than by a minimum difference is 1 and similarly strictly greater element means the number should be greater than by a minimum of difference 1. Here we have given an array of integers of size n and we have to return the count of elements in the array having strictly smaller and strictly greater elements present. Let's see examples with explanations below to understand the problem in a better way. Sample Examples Input N = 5 Array: [ 3, 2, 1, 4, 5 ] ... Read More
We are given an integer B and A, and we have to convert the number K from 0 to exactly B by applying the given operations in the minimum steps. We can increase the current number K by 1 i.e. K = K + 1 We can add the product of the number A with any power of 10 to the number K i.e. K = K + A * 10^p, where p is any non-negative number. Sample Examples ... Read More
Python is a popular programming language that is used extensively in the field of data analysis, machine learning, and scientific computing. When working on projects, it is common to work with multiple files simultaneously. In Python, there are different approaches to opening two or more files at once. In this article, we will learn how to open two files together in Python. The fundamental Python features that enable users to interact with computer files are the file read and write operations. Python gives worked−in capabilities to perusing, composing, and controlling records in different organizations. File reading is the method ... Read More
