I'm pretty sure this is what they meant...

  def my_func():
      group_keys = 'My thing'
      while group_keys == 'My Thing':
          if some_logic() == 42:
              groups_key = 'My other thing'  # typo here

I don't see how that's avoidable in any language that doesn't require explicit variable declaration

Yeah, that's the point. Python doesn't have it. It'd be better if it did.

compiler/IDE would complain about "unused local variable"
