Web Scraping
When I created this piece of code I thought it would be cool to develope a Codewars challenge that incorporated webscraping. This function scraps and retrieves the stats of a valid codewars username using the requests and BeautifulSoup module. If a valid username is entered the output will look as such:
Output:
username's Codewars stats:
Member Since:Jan 2020
Rank:4 kyu
Honor:1500
Leaderboard Position:#10,040
Honor Percentile:Top 2.354%
Total Completed Kata:776
Feel free to modify, and improve the code.
