I would be really thankful if you could check out them because I'm kinda indecisive about everything and i want your opinion on this. I was looking for a website that would have programming problem sets set in order so i could solve them and also have fun. I'm a python newbie and this is what i found to be the most interesting: 1. CodeAbbey - http://www.codeabbey.com/index/task_list 2.CoderByte - https://coderbyte.com/challenges 3. CodeChef - https://www.codechef.com/problems/school/ 4. ProjectEuler (particulary interesting) - https://projecteuler.net/about I'm leaning towards the 4th one but would like a feedback on all of them. Thanks :-) PS: How do you change the headline if you made a mistake and already posted xD?
