[QUOTE="SL MULTIMEDIA TUTORIAL, post: 27628557, member: 575597"] mekata Code enne kohomada 👀 There are two online supermarkets which provide price of various products. You need to write a program to acquire, extract and compare the price from these two suppliers, for a given product. Example: Price of a coconut from the two different suppliers can be found in the following webpages. laughs_coconut = '[URL]https://www.laugfssuper.com/index.php/coconut-105320.html[/URL]' (Please check the update note at the end of the question) glomark_coconut = '[URL]https://glomark.lk/coconut/p/11624[/URL]' The function def compare_prices(product_laughs,product_glomark) will take-in two similar products from two suppliers, and compare the prices to recommend you which option is cheaper on a given instance of time. 1. Visit the links in your web browser, and use the Inspect elements / View page source tools of the browser to understand the structure of the web pages given above. 2. Complete the compare_prices function which is pre-loaded in the answer box to acquire and extract the price values from two web pages. When you submit your answer to be checked, be patient for a while (up to 20 seconds) until its been checked with multiple test cases. Example expected output Laughs COCONUT - Item#mr-2058 Rs.: 89.0 Glomark Coconut Rs.: 86.0 Glomark is cheaper: 3.0 Here are some more test cases for you to test in your own computer. laughs_tissues = '[URL]https://www.laugfssuper.com/index.php/categories/household/flora-facial-tissues-2-x-160-box.html[/URL]' glomark_tissues = '[URL]https://glomark.lk/flora-facial-tissues-160s/p/10470[/URL]' compare_prices(laughs_tissues,glomark_tissues) laughs_bread = [URL]https://www.laugfssuper.com/index.php/crimson-bread-sliced-111452.html[/URL]' glomark_bread = '[URL]https://glomark.lk/top-crust-bread/p/13676[/URL]' compare_prices(laughs_bread,glomark_bread) **Update:Laugfs website seems to be slow and changing quite frequently. So a backup of the required web pages are available in the following links.
