Regular expressions, commonly referred to as regex, are powerful tools for pattern matching and manipulation of text in Python. They allow you to define patterns and search for matches within strings, making them extremely useful in various applications such as data validation, text processing, and web scraping. In regex, metacharacters play a crucial role. These special characters have a predefined meaning and are used to build complex patterns. Understanding and utilizing metacharacters effectively can significantly enhance your regex skills. In this article, we will explore the world of Python regex metacharacters. We will learn about different metacharacters and how they ... Read More
Data visualization is crucial for efficient information comprehension and presentation. Among the many chart types available, waffle charts offer a novel way to display data as square tiles in a grid-like structure. The powerful Python module PyWaffle facilitates Waffle chart development, similar to many calculations and data analysis methods. In this article, we'll look at how to create a waffle chart using the sophisticated Python module PyWaffle. Let's install PyWafle and see how categorical data can be visualized with it. Run the following command in your cmd to install the library and then import it into your code. ... Read More
Commonly used in statistical analysis and data modelling, the Gaussian distribution, alternatively referred to as the normal distribution, presents a familiar bell-shaped curve that represents a continuous probability distribution for a real-valued random variable. Its bell-shaped curve characterises it and is often used to model real-world phenomena. The random module generates a set of pseudorandom numbers drawn from a normal distribution with a stipulated mean and standard deviation. Syntax numpy.random.uniform(low=0.0, high=1.0, size=None) Parameters low : It takes floating or array like values as its argument represents the minimum value that can be generated. The default value is ... Read More
Tinyhtml is a Python library used to generate HTML5 expressions or code. This is useful for generating HTML code when you are not as knowledgeable about the syntax of HTML. As the name says so, it is a ‘tiny’ library and can render HTML5 expressions. There are many methods of rendering HTML code using tinyhtml few of which we’ll be seeing. To learn more, go through the documentation here. Due to the lightweight nature of tinyhtml, it is easier to integrate it with other tools, for example, HTML code snippets can be rendered in Jupyter Notebooks by importing ... Read More
In the study of statistics and data-analysis, normal distribution or Gaussian Distribution is a widely used probability distribution. It is a bell-shaped curve that characterizes the probability and is often used to model real-world phenomena. We use the random module available in Python’s Numpy library to generate random numbers from the normal distribution. It also allows users to generate random numbers from the normal distribution with a specified mean and standard deviation. Syntax numpy.random.normal(loc=0.0, scale=1.0, size=None) Parameters loc (float or array_like): It is the mean or centre of the distribution. The default value is 0.0 ... Read More
Chebyshev series is a polynomial series referring to a series of Chebyshev Polynomials. A Chebyshev Polynomial is a Polynomial that is defined in a specific interval which is orthogonal in nature. It has a weight function $\mathrm{(1-x^{2})^{(-½)}}$. This polynomial is named after the Russian mathematician, Pafnuty Chebyshev. Orthogonality is a specific type of relationship that defines two polynomials. Two polynomials are orthogonal in nature if their relationship satisfies certain conditions. For example, two functions can be considered orthogonal if their integration over a certain interval equates to 0. Chebyshev Polynomials are defined as \mathTn(x). They are defined recursively ...

RPC and SOAP are two methods for implementing remote procedure calls between distributed systems. SOAP is a protocol that encodes messages in XML and transports them through HTTP or HTTPS. Remote Procedure Call (RPC) is a protocol that allows a client application to call a remote server's method or function as if it were a local function call. Read this article to find out more about RPC and SOAP and how they are different from each other. What is RPC? Remote Procedure Call (RPC) is a protocol that allows a client application to call a remote server's method or function ... Read More
An operating system (OS) is a system software that manages the computer hardware and software, and it provides services and functionality to programs and users. A real-time operating system (RTOS) is a segment of an operating system that is designed to provide predictable and deterministic behavior for time-critical applications. While RTOS and general-purpose OS have certain similarities, they also have some major differences. Read this article to find out more about RTOS and OS and how they are different from each other. What is a Real-Time Operating System? A real-time operating system (RTOS) is a type of operating system that ... Read More
Coaxial cables such as RG6 and RG11 are used for transmitting high-frequency signals over long distances. The two cables' principal differences are their sizes, the level of signal loss they go through over a given distance, and their maximum bandwidth. RG6 and RG11 coaxial cables are both used for transmitting high-frequency signals, with RG11 being larger and more resilient than RG6 and having reduced signal loss over long distances. Read this article to find out more about RG6 and RG11 and how they are different from each other. What is RG6? RG6 is a type of coaxial cable used for ... Read More
Intranet and Portal are both used within organizations to help organize and share information, but they differ significantly. An Intranet is a private network that only employees within a company can access. A Portal is a web-based platform that allows access to numerous types of information and services. Read this article to find out more about Intranet and Portal and how they are different from each other. What is Intranet? An intranet is a private network that allows employees within a company to share information and resources. It is an efficient and secure way to facilitate internal communication and cooperation, ...
