A Donut chart is a circular chart that shows the relative representation of the data in a circular way. Donut and pie charts look similar but the donut chart has a hole in the center of the chart whereas the pie chart doesn’t. A donut chart can be created for a dataset containing various groups in different proportions using Matplotlib. In this article, we will create a Donut chart using Matplotlib. Algorithm The donut chart in Matplotlib can be drawn using the methods provided by the matplotlib library. We can follow the below algorithm to make a Donut chart ... Read More

Pygal is a Python library that is used for creating graphs and charts for data visualization. The donut chart is a type of pie chart with a hole in the middle. Donut chat can be easily created using the Pygal library. In this article, we will visualize sample data using a Donut chart. Installing Pygal library Before we start using the Pygal module, we need to install the Pygal library in our system by using the Python package manager. Type the following command in your terminal or command prompt to install the Pygal library. pip install pygal Algorithm ... Read More

Docopt module in Python is used to create command-line interfaces. Similar to other command line arguments and options docopt allows us to define command line arguments and options and also generate help messages and usage strings for the Program. In this article, we will understand how the Docopt module is defined and how it is used to create a command line interface. Installation You can install the Docopt module before using it with the help of the pip command in Python. To install the Docopt module type the following command on your terminal or command prompt. pip install docopt ... Read More

The dllist is a class of the llist module in Python that is used to implement a doubly linked list that has the functionality for insertion, deletion, and traversal of elements. The dllist class provides methods for adding, removing, and iterating over the list in both directions. In this article, we will understand the dllist class in detail and its methods. Creating dllist object To create a dllist object, we need to first import the llist module from the pyllist package. We can then use the dllist class constructor to create a new instance of a doubly-linked list. The ... Read More

Dataclass, NamedTuple, and Object are used to create structured datatypes in Python. Though all three are used to create structured data they differ in their properties and implementation method. In this article, we will understand the difference between DataClass, NamedTuple, and Object in Python. Feature Object NamedTuple Dataclass Creation Objects are created by defining a class and its attributes and methods manually. Named tuples are created using the named tuple function from the collections module. The field names and values are specified manually. Data classes are created using the @dataclass decorator. The class attributes ... Read More

Adam optimizer in Tensorflow is an algorithm used in deep learning models. Optimization algorithms are used in deep learning models to minimize the loss function and improve performance. Adam stands for Adaptive Moment Estimation, which is a stochastic gradient descent algorithm. It combines the advantages of both RMSprop and AdaGrad algorithms to achieve a better optimization result. In this article, we will understand the Adam Optimizer in Tensorflow and how it works. Working principle of Adam Optimizer Adam optimizer is an iterative optimization algorithm. It uses first and second-order moments of the gradient to adaptively adjust the learning rate ... Read More

The Factory Method Design Pattern of Python is a creational pattern that provides an interface for creating objects in a superclass but allows subclasses to alter the type of objects that will be created. It is used to define a generic interface for creating objects while allowing subclasses to decide which class to instantiate. In this article, we will explore how to use the Factory Method Design Pattern to access web resources in Python. Accessing Web Resources Python provides several libraries for accessing web resources such as HTTP requests, urllib, and Requests. These libraries allow us to send HTTP requests ... Read More

Machine Learning and Artificial Intelligence a major trend dark of the IT business. While conversations over the security of its advancement continue to raise, designers grow capacities and limit counterfeit acumen. Today AI has gone a long way past sci-fi thought, and it turned into a need. Being generally utilized for handling and dissecting gigantic volumes of data, AI assists with taking care of the work that isn't possible physically any longer due to its expanded volumes and power. Spam channels, search engines, and recommendation systems are completely made conceivable by artificial intelligence and AI, and there are certainly more ... Read More

Text data manipulation and processing can benefit from using a Python program that will eliminate the last specified character from a string. This kind of application can be used to modify data by deleting particular characters, validate user input by removing incorrect characters, and clean up the text by removing unwanted characters. In Python, we have some string in-built functions like rstrip() that remove the last specified character from the string. The slicing technique is the easier way to remove the character from the end. Syntax The following syntax is used in the examples − len() The len() ... Read More
