Create a webpage A2-Task2.html. The webpage is displaying one image. Each time the user moves the mouse out of the image, the image is changed to another one and one more 'sun' emoji is displayed under the image. When the number of 'suns' reaches seven (7), all 'suns are deleted (reset) and start to be displayed again. For example, the 8th time user moves the mouse out of the image, one 'sun' is shown, the 9th time - two 'suns', and so on. Note: - You should use two images. Each time the user moves the mouse out of the image, the image is changing. If an image of "Winter" is displayed it will change to "Summer", and opposite, if an image of "Summer" is displayed it will change to "Winter". The special character code for the 'sun' is "☀". Put the source code of your website A2-Task2.html here. Make sure you also upload the A2-Task2.zip of all files below.

Inside the anonymous function: the function toggleComments is called with the event and postId as parameters h. Return the button elements which were selected i.

Scenario: You have been tasked with building a URL file validator for a web crawler. A web crawler is an application that fetches a web page, extracts the URLs present in that page, and then recursively fetches new pages using the extracted URLs. The end goal of a web crawler is to collect text data, images, or other resources present in order to validate resource URLs or hyperlinks on a page. URL validators can be useful to validate if the extracted URL is a valid resource to fetch. In this scenario, you will build a URL validator that checks for supported protocols and file types.
Although this dataset does not havee any NaN S, you could utilizee the dropna function to drop rows with missing values. We will not be providing links to the relevant page in the Pandas API anymore. Instead, you should develop the habit of Googling and finding out how to use the API on your own, which is an important skillfor working with Python libraries. Once you are done with that, print out summary information on the table again to ensure that the changes are saved. Your code here spotify_na- ? spotify_na.?
Add in loader spinners within each button in the Logs page. Currently it takes a very long time to load players/stats/etc. This is understandable given the amount of data. While the query is going on behind the scenes, please add loaders into the buttons — Player, Stats, Min/Max Timestamps (and make them non-clickable) — so that is it clear what the user is waiting on. Here is the filter code: import { map } from 'lodash'import React from 'react'import { Button } from 'reactstrap' import * as Dropdowns from './dropdowns' const isSubmittable = filterOptions => {if (!filterOptions.sport|| !filterOptions.schema|| !filterOptions.event) return false return true} const BetFeedFilters = props => {const { metadata, selectedMetadata, updateApiDropdown, filterOptions, events, players, stats, timestamps, submitApiCall, loading } = props if (!metadata) return <div></div> return (<div style={{ paddingTop: 10, paddingBottom: 10, display: 'flex', flexDirection: 'column', gap: 20,…
Create a webpage A2-Task2.html. The webpage is displaying one image. Each time the user clicks the image, the image is changed to another one and one more 'globe' emoji is displayed under the image. When the number of 'globes' reaches five (5), all 'globes' are deleted (reset) and start to be displayed again. For example, the 6th time user clicks the image, one 'globe' is shown, the 7th time - two 'globes', and so on. Note: - You should use two images. Each time the user clicks on the image, the image is changing. If an image of "Seaside" is displayed it will change to "Mountain view", and opposite, if an image of "Mountain view" is displayed it will change to "Seaside". - The special character code for the 'globe' is "🌏".
