In this article, we will show you how to remove the index list elements from the original list using python. Now we see 2 methods to accomplish this task − Using pop() method Using del keyword Assume we have taken a list containing some elements. We will remove the index list elements from the main list using different methods as specified above. Note We must sort the indices list in descending order because removing elements from the beginning will change the indices of other elements, and removing another element will result in an incorrect result due to misplaced ...

In Python, a list is an ordered sequence that can hold several object types such as integer, character, or float. In this article, we will show you how to join the list of lists(nested lists) using python. Now we see 4 methods to accomplish this task − Using nested for loop Using List comprehension Using sum() function Using NumPy module Assume we have taken a list of lists containing some elements. We will join those list of lists and return the result using different methods as specified above. Method 1: Using nested for loop Algorithm (Steps) Create a ... Read More
In Python, a list is an ordered sequence that can hold several object types such as integer, character, or float. In other programming languages, a list is equivalent to an array. In this article, we are going to append the list to another list(Concatenate Lists) in Python. The following are the different methods to accomplish this task − Using Concatenation(+) Operator Using the append method of the list object Using extend() Method Using itertools.chain() Method Obtain a list without duplicates Assume we have taken a list containing some elements. We will return the concatenated list of the given ... Read More
Array is a structure, which can hold values elements and they can be accessed by referencing to them with the help of index numbers. Const colors = [“Green”, “Maroon”, “Blue”]; Reference index of array In JavaScript arrays are referred with reference indexes. These indexes are zero-indexed. The very first element in the array will be 0 index. Second element will be index 1. Last element in the array will be the total size of the array minus 1. Spread operator (…) In this article, we are going to discuss how to remove the 0th indexed element in an ... Read More
Floating point A number which is either positive or negative whole number with having a decimal point to it is called floating point. Let’s consider these numbers, 1.52, 0.14 and also -98.345 are considered as floating point numbers. Whereas 77, 56, 90 and 0 are not considered as floating point numbers. In JavaScript this format will store the numbers in 64 bits. The numbers which are in fraction are stored in 0 to 51 bits. Coming to exponent, they are stored in 52 to 62 bits. And the sign bits will be stored in 63rd bit. Floating point arithmetic Floating ... Read More
In this article, we are going to discuss how to convert a string to a floating-point number in JavaScript. We can convert a string to a floating point in three ways − Using the parseFloat() method. Using the parseInt() method. Using type conversion. Using the parseFloat() method The parseFloat() is a function in JavaScript, this accept the string as input and convert the value into a floating point number. Let’s consider a scenario where there is numeral value in the string and also if the first character of the string is not a number then the resultant output ... Read More
Arrays is typeof operator in JavaScript. Arrays can access its elements with the help of index numbers which starts with 0. Let array = [“India”, “Australia”, “USA”]; There are enough number of ways to get the common elements from the arrays. Now, In this below scenario we use for loop for finding common arrays. In this article, we are going to discuss how to find the common elements between two or more arrays in JavaScript. Using for loop One way to find the common elements between two or more arrays is using the simple for loop. Following are the ... Read More
In this article, we are going to discuss whether provided elements in an array have passed a specified condition or not in JavaScript. Here, we can use the _.filter() method, every() method, some() method, filter() method, and for loop. They return true if every element in an array has met the condition, otherwise, they return false. Using the Array.filter() method This Array.filter() method is a JavaScript function. Array.filter() method will be creating a new array containing the elements that are passed in the condition which is defined by function in program. This Array.filter() method will not execute if elements are ... Read More
Radio button A radio button is used to select one among many options. This is one of the element in HTML. This radio button is a radio group to show a set of multiple choices, and in that only one can be selected. This way far similar to checkboxes, in checkboxes scenario’s we can select either one or many options as we can, whereas in radio button it can’t be done selecting multiple choices. We can define radio button is HTML using tag. Following is the syntax to define radio buttons in HTML Example 1 None selected ... Read More
Events in HTML are “things” that take place using HTML elements. JavaScript can “respond” to these events when used in HTML pages. Events are produced as a result of user interaction with the elements of the user interface. The actions that trigger an event include, for instance, pressing a button, moving the mouse, typing a character on the keyboard, choosing an item from a list, and scrolling the page. Examples of HTML events are mentioned below − An HTML web page has finished loading An HTML input field was changed An HTML button was clicked Adding an event ... Read More
