UoM Online Course 3 - Python Programming ඉවර කරපු අය...

course එක ඉවර කරපු කෙනෙක් ඉන්නවානම් කියන්න පුලුවන්ද Programming Assessment එකේ Code එක එන විදිහ Try කරලා බැලුවා . කරගන්න බැරි නිසා help එකක් ඉල්ලලා බලන්න හිතුනේ..

Programming Assessment එක​

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 = 'https://www.laugfssuper.com/index.php/coconut-105320.html' (Please check the update note at the end of the question)
glomark_coconut = 'https://glomark.lk/coconut/p/11624'

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 = 'https://www.laugfssuper.com/index.php/categories/household/flora-facial-tissues-2-x-160-box.html'
glomark_tissues = 'https://glomark.lk/flora-facial-tissues-160s/p/10470'
compare_prices(laughs_tissues,glomark_tissues)

laughs_bread = https://www.laugfssuper.com/index.php/crimson-bread-sliced-111452.html'
glomark_bread = 'https://glomark.lk/top-crust-bread/p/13676'
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. Your answers will be validated against these pages.:
