In this article, we will learn about the use of the Keyboard module in Python 3.x. Or earlier.Ide preferred − Jupyter notebookInstallation −>>> pip install keyboardFunctionalities of the module −Allows us to block the action of specific keysWe can manage intents from the keyboard using on click listeners.Cross-platform compatibility.Supports special & hotkeys available on the keyboard.Now let’s implement this in the form of code −Exampleimport keyboard # It writes the content keyboard.write("Tutorialspoint") # It writes end of line keyboard.press_and_release('shift + o, shift + y, ') keyboard.press_and_release('k, j') # it blocks until ctrl keyboard.wait('Ctrl')OutputTutorialspoint O Y k jExampleimport keyboard # It ...

In this article, we will learn about Kivy framework and its installation. Kivy is a GUI based application interface, open-source that helps in cross-platform applications for Windows, Linux and Mac.Installation GuideFirstly we need to install python on pc.After that we need to install the dependencies −Windows −>>> python -m pip install docutils pygments pypiwin32kivy.deps.sdl2 kivy.deps.glew >>> python -m pip install kivy.deps.gstreamer >>> python -m pip install kivy.deps.angleLinux −$ sudo add-apt-repository ppa:kivy-team/kivyInstalling the Kivy fileWindows −>>> python -m pip install kivyLinux −>>> sudo apt-get install python3-kivyNow let’s see how we can make a graphical user interface using Kivy −Exampleimport kivy kivy.require('1.10.0') ...

In this article, we will learn about What is the Python Global Interpreter Lock (GIL).This is a lock or hindrance that resistant the availability of the Python interpreter to multiple threads simultaneously. GIL is identified as a fault/issue in Python 3.x. Or earlier as it doesn’t allow multithreading in a multi-threaded architecture.Why is it introduced?Python supports the concept of automatic garbage collection. As soon as the reference count of an object reaches zero the memory is cleaned and free for usage.>>> import sys >>> var = {} >>> print(sys.getrefcount(ar)) >>> 2 >>> v=var >>> print(sys.getrefcount(v)) >>> 3Of in this case ...

In this article, we will learn about vectorization and various techniques involved in implementation using Python 3.x. Or earlier.What is Vectorization?Vectorization is a technique to implement arrays without the use of loops. Using a function instead can help in minimizing the running time and execution time of code efficiently. Various operations are being performed over vector instead of arrays such as dot product of vectors which is also known as scalar product as it produces single output, outer products which results in square matrix of dimension equal to (length X length) of the vectors, Element wise multiplication which products the ...

In this article, we will learn about isprintable() in Python and its application.Is printable() is a built-in method used for the purpose of string handling. The isprintable() methods return “True” when all characters present in the string are of type printable or the string is empty, Otherwise, It returns a boolean value of “False”.Arguments − It doesn’t take any argument when calledList of printable characters include digits, letter, special symbols & spaces.Let’s look at this illustration to check that whether the characters of string are printable or not.Example Live Demo# checking for printable characters st= 'Tutorialspoint' print(st.isprintable()) # checking if ...

In this article, we will learn about the basics of machine learning using Python 3.x. Or earlier.First, we need to use existing libraries to set up a machine learning environment>>> pip install numpy >>> pip install scipy >>> pip install matplotlib >>> pip install scikit-learnMachine learning deals with the study of experiences and facts and prediction is given on the bases of intents provided. The larger the database the better the machine learning model is.The flow of Machine LearningCleaning the dataFeeding the datasetTraining the modelTesting the datasetImplementing the modelNow let’s identify which library is used for what purpose −Numpy − adds ...

We bundle the files in React application using tool such as webpack. Bundling in the end merges the files in the sequence of their imports and creates a single file.The problem with this approach is that the bundle file gets larger with the increase in files. User may not be sung all the feature components but still bundle is loading them, this could affect the loading of application.To avoid this, code splitting is used in React.ExampleExample of bundling −// app.js import { total } from './math.js'; console.log(total(10, 20)); // 42 // math.js export function total(a, b) { return a ...

The aria-* attributes on html elements are also supported in React.js as well. The other attributes are generally written in camel-case but these aria-* are written in hyphen-cased.Sometimes we break the semantics of the html if we use parent div in React.jsExamplerender(){ return( Test ); }Div can cause semantics issue if working with table, list etc. To avoid this we can use React provided fragment as shown below −import React, { Fragment } from ‘react’; function MessageList({ message }) { return ( ...

React community has provided a direction on how to think in React way and build big , fast and scalable applications. React has reached multiple platforms and widely used a popular JavaScript UI interface library.Step 1 − Creating a simple mock serviceIf we need to make a server call and fetch data. We can create a mock service to start with and build a component to fetch and display data.Here we can include the processing of json in component and evaluating the expected result.Step 2 − Break the functionality into smaller componentsThe first Thing React suggest is to create the ...
