HTML (Hypertext Markup Language) is the foundation of the internet. Websites use HTML to create and display content in a structured manner. In many cases, it's necessary to modify HTML code to add new elements, remove unwanted elements, or make other changes. This is where BeautifulSoup comes in. BeautifulSoup is a Python library that allows you to parse HTML and XML documents. It provides a simple interface for navigating and searching the document tree, as well as for modifying the HTML code. In this article, we'll learn to modify HTML using BeautifulSoup. We will learn the steps of modifying HTML ... Read More

CSV (Comma Separated Values) files are widely used for storing and exchanging data in a simple format. In many data processing tasks, it is necessary to merge two or more CSV files based on a specific column. Fortunately, this can be easily achieved using the Pandas library in Python. In this article, we will learn how to merge two CSV files by a specific column using Pandas in Python. What is Pandas Library? Pandas is an open-source library for information control and examination in Python. It offers tools for working with structured data, such as tabular, time-series, and multidimensional data, ...

Time series data is a crucial part of many business operations, especially those in the finance and manufacturing industries. These datasets often come in multiple tables or files, with each table containing a specific subset of the data. Merging these tables can be a challenging task, mainly when the tables contain data that does not match. In this article, we will learn how to merge time series data that does not match using Pandas. Pandas is a powerful data analysis library in Python that provides extensive tools for merging and manipulating data. We will also learn the different techniques to ... Read More

Python is a versatile programming language that offers programmers various modules and libraries to perform the required tasks. One such powerful function that Python offers is the “cbind”. This stands for column bind. The “cbind” is a powerful tool that allows programmers to combine, merge, and group the arrays, data frames, etc., in Python column-wise. In this article, we will learn how to use the “cbind” in Python. Using zip and list comprehension Zip and list comprehension are two very popular techniques used in many expressions in Python. The zip function can help to combine multiple elements from different iterables. ... Read More

As a programmer, when we need to deal with data, we may need to perform operations only in rows or columns, or both. In pandas, the axis refers to how a function or an operation is applied to the Data Frame or the series. Pandas only can take two values, either 0 or 1, as an argument to the axis property. In this article, we will learn how to use the axis=0 and axis=1 in Pandas. Understand the axis Before we move forward, let us brief you on the axis of pandas. As we know, the data frame in pandas ...

Dictionaries are among the most powerful data structures in Python programming languages. This is a data structure consisting of key-value pairs. It has several advantages; for example, accessing the values occurs in O(1) time complexity, it is memory efficient, easy to update, delete and iterate, and offers many built functions for quick operations. Problem Associated When Lists Are Used Directly We are focusing on this topic because there is a problem associated with when we try to make the lists as the key. Lists are mutable data types in Python. Hence, we can delete, update, and append values inside the ... Read More

PyTorch is a popular open-source machine-learning library. Data scientists, researchers, and developers use this library widely to develop AI/ML products. One of the most important features of PyTorch is the Data Loader class. This class helps to load and batch the data for neural network training efficiently. This article will teach us how to use the Data Loader in PyTorch. Use Data Loader In PyTorch We can follow the following basic rules to perform the Data Loading operation in Python using the PyTorch library − Data Preparation − Create a custom Random Dataset class that generates a random dataset ...

Dictionaries are powerful data types of Python. It consists of key-value pairs. Operations like searching, appending, etc., can be done efficiently through this data type. While accessing values in a dictionary is straightforward, there may be situations where you need to find the next key in a dictionary. Python provides several ways to achieve this, depending on your specific requirements. In this article, we will explore different methods to get the next key in a dictionary in Python. Using The keys And index Method The dictionaries are unordered collections in Python. Hence we first need to convert the keys into ... Read More

Generating random numbers is one of the most popular techniques in programming, statistics, machine learning models, etc. Generating a sorted list of random integers with unique elements is a subdomain of the task. However, computers are deterministic machines, so generating random numbers through our implementation is only sometimes a smart idea. In this article, we will explore how to Get a sorted list of random integers with unique elements using Python. Utilizing Sample Function Of Random Module The sampling method generates random samples of k elements from a given population. It takes two required parameters first is the list of ... Read More

Generating random data is important in the field of data science. From building Neural Networks forecasting, stock market data, etc., often come with dates as one of the parameters. We may need to generate random numbers between the two dates for statistical analysis. This article will show how to generate k random dates between two given dates Use random and date time Modules The date time is an in-built library of Python to deal with time. The random module, on the other hand, helps to produce random numbers. Hence, we can combine the random and date time modules to generate ... Read More
