• How to level up progress?


So, my progress says that to get to the next stage I need 5 of the following 6 things:

  • isinstance
  • collections
  • datetime
  • functools
  • itertools
  • with

However, according to what I found, "collections" has been deprecated for a while and will soon be removed, and "with" can only be used when opening a file (does that even happen on checkio, I haven't seen it yet). So I'm stuck.

Suggestion: either make the requirement 4 out of 6 or add an additional thing to the list
