Pytorch is an open-source machine learning framework that is widely used to create machine learning models and provides various functions to create neural networks. The activation function is a key component of neural networks. The activation function determines the output of a node in the neural network given an input or set of inputs to the node. The activation function introduces non-linearity in the output of a node of the neural network which is necessary for solving complex machine-learning problems. What is an Activation Function ? Neural networks in artificial intelligence consist of an input layer, a hidden layer, and ... Read More
Action chains in selenium python are the execution of multiple browser actions together in sequence. Selenium is a popular open-source automation testing tool used to test web applications and automate browser actions. Selenium can chain multiple browser actions together and this chaining of multiple actions is known as Action chains. In this article, we will discuss what action chains are in selenium python and how to use action chains to automate our web testing. What are Action Chains in Selenium Python? Action chains are a sequence of actions that are performed in a specific order on a web page to ... Read More
We can access the metadata of audio files using Mutagen and the eyeD3 module in Python. For video metadata, we can use movies and the OpenCV library in Python. Metadata is the data that provides information about other data like audio and video data. Metadata of audio and video files include the format of the file, resolution of the file, file size, duration, bit rate, etc. By accessing these metadata we can manage the media more efficiently as well as analyze the metadata to get some useful information. In this article, we will look at some of the libraries or ... Read More
If multiple devices are connected over the same network i.e LAN or wifi then Python provides a way to access the files of the devices sharing the same network. Python built-in http.server module allows us to easily access the files of the devices connected over the same network. Http.server is a simple server that serves devices from the current directory or the chosen directory of the device when a request on the server is done. In this article, we will discuss the steps involved in accessing the files of a device in the same network using Python. Step 1 : ... Read More
Environment variables in Python are configuration values stored outside the code and are used at runtime by the application. These variables are present in the form of key-value pairs just like dictionaries in Python. These variables can be set, updated, or removed from the configuration file without changing the application code. Python gives many operating systems functions to access environment variables without affecting the code of the application. In this article, we will learn the ways in which we can access environment variables in Python. Using the OS Module In order to interact with the operating system python has an ... Read More
Tkinter is a Python library that is used to make desktop applications for Windows and UNIX-based Operating systems. Tkinter gives many choices to make a widget for the application. The same widget can be made in different ways using Tkinter. Today there are vast sources of information available on the internet. News is constantly coming from global sources to local sources. Keeping track of the latest news is a daunting task. In this article, we will build a simple News app with Tkinter and Newsapi. What is Newsapi? News API is an (Application programming interface) that provides access to news ... Read More
Pygame is an open-source Python library used for making games. Pygame library provides various functions and tools for creating games, sound processing, and graphics.pygame library can be used to create games on any operating system like Windows, Linux, and macOS as pygame is a cross-platform library. What is an 8-bit Game? The 8-bit game was very popular in the 1980s. The 8-bit video games included graphics and sound that were created using 8-bit technology i.e a limited color palette and sound range that fall within the 8-bit range were used to create such video games. In this article, we will ... Read More
Object-oriented programming language is a programming paradigm that is widely used in software design as it makes the code reusable and reduces code redundancy. It uses classes and objects to implement real-world objects in programming. Python and other languages like C++, java, javascript, etc support object-oriented programming. In this article, we will understand the characteristics of object-oriented programming and some tips to use object-oriented programming in Python. In object-oriented programming, objects are created from their class blueprint. These objects represent real-world objects as they have some properties called attributes and methods just like real-world objects have their own properties and ... Read More
What is Air India? Air India (AI)is the national flag carrier of India, and it operates both domestic and international flights. The airline was founded as Tata Airlines in 1932 by J.R.D. Tata, a pioneering Indian aviator. In 1946, the airline was renamed Air India, and it became the country's flag carrier after India gained independence in 1947. Air India is headquartered in Mumbai, and it operates a modern fleet of Boeing and Airbus aircraft. Figure ... Read More
Definition and Explanation of Automatic Frequency Control Automatic Frequency Control (AFC) is a technique used in communication systems to ensure that the carrier frequency of a transmitted signal remains at a constant and accurate frequency. To address this issue, AFC uses a feedback mechanism to detect any changes in the carrier frequency of the received signal and then adjust the frequency of the local oscillator at the transmitter accordingly to maintain a constant frequency. The feedback mechanism works by comparing the received signal's frequency with a reference frequency generated at the receiver. Any difference between these two frequencies is used ... Read More
