Can anyone explain this one?

Sure. You have to solve it from inside out:

  • not()....See comment below for this one, I was tricked ~~is a base function that negates what's inside (turning True to False and vice versa) giving it no parameter returns "True" (because no parameter counts as False)~~
  • str(x) turns x into a string, in this case it turns the boolean True into the text string 'True'
  • min(x) returns the minimal element of an iterable. In this case the character 'T' because capital letters come before non-capital letters, otherwise it would return 'e' (I'm not entirely sure if it uses unicode, ascii or something else to compare characters, but usually capitals have a lower value than non-capitals and otherwise in alphabetical order ascending)
  • ord(x) returns the unicode number of x, in this case turning 'T' into the integer 84
  • range(x) creates an iterable from 0 to x (non-inclusive), in this case you can think of it as the list [0, 1, 2, ....82, 83] (it's technically an object of type range but details...)
  • sum(x) sums up all elements of a list, summing all numbers between 0 and 84 (non-inclusive) is 3486
  • chr(x) is the inverse of ord(x) and returns the character at position x, which, you guessed it, is 'ඞ' at position 3486.

The huge coincidental part is that ඞ lies at a position that can be reached by a cumulative sum of integers between 0 and a given integer. From there on it's only a question of finding a way to feed that integer into chr(sum(range(x)))

not() is a base function that negates what’s inside (turning True to False and vice versa) giving it no parameter returns “True” (because no parameter counts as False)

Actually, not is an operator. It makes more sense if you write not() as not () - the () is an empty tuple. An empty tuple is falsy in Python, so not () evaluates to True.

I'm not entirely sure if it uses Unicode, ASCII or something else...

I think I remember Automate the Boring Stuff with Python explaining that python uses ASCIIbetical order, but it's been a minute since I read that book
