world hello 0%

Hello!

I'm new here. In my profile I can see some kind of quest "0% Hello World". As far as I understand it should fulfil when I use some Python keywords, builtins, etc. in my solutions. I resolved few solutions and used there keywords from a quest (len, if, for) but nothing changed. I even tried resolve exactly the task under "Try the following missions with if:" section.

I thought maybe it is because I'm using PyCharm integration for solutions. Tried to resubmit via browser already resolved solution - nothing changed

I like this platform and want to check all the functionality it suggests. So be happy for any of help

Thank you:)
