I need help with this one please, already tried but still getting a wrong answer 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. Task Create two lists of strings – one list for Protocol called valid_protocols, and one list for storing File extension called valid_fileinfo. For this take the protocol list should be restricted to http, https and ftp. The file extension list should be .html, .csv and .docx. Split an input named url, and then use the first element to see whether the protocol of the URL is in valid_protocols. Similarly, check whether the URL contains a valid file_info. Write the conditions to return a Boolean value of True if the URL is valid, and False if either the Protocol or the File extension is not valid.

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.

Task

Create two lists of strings – one list for Protocol called valid_protocols, and one list for storing File extension called valid_fileinfo. For this take the protocol list should be restricted to http, https and ftp. The file extension list should be .html, .csv and .docx.

Split an input named url, and then use the first element to see whether the protocol of the URL is in valid_protocols. Similarly, check whether the URL contains a valid file_info.

Write the conditions to return a Boolean value of True if the URL is valid, and False if either the Protocol or the File extension is not valid.
