In case anyone's curious:

not() # True
str(not()) # 'True'
min(str(not())) # 'T'
ord(min(str(not()))) # 84
range(ord(min(str(not())))) # range(0, 84)
sum(range(ord(min(str(not()))))) # 3486
chr(sum(range(ord(min(str(not())))))) # 'ඞ'

You forgot the most important part!

print(chr(3486)) # ඞ

It could be an impostor

It looks like the characters from the game Among Us.

[–] Kolanaki@pawb.social 7 points 4 days ago

It could be a monster.

Looks like telugu

[–] devfuuu@lemmy.world 20 points 4 days ago (2 children)

What kind of dumb language is this?

[–] takeda@lemm.ee 23 points 4 days ago* (last edited 3 days ago)

Python, but this is actually defined and documented behavior.

Edit: to illustrate what I mean:

not() # True

this actually is not () (the lack of space makes it look like a function), () is a tuple, in python an empty collection returns False, this is to make checks simpler. You can type:

if my_list:
  do something

instead of

if len(my_list) > 0:
  do something

not negates it so you get True

str(not()) # 'True'

converts resulting bool type into a string representation

min(str(not())) # 'T'

This might feel odd, but that's also documented. min() not only allows to compare two numbers like it is in most languages, but you can also provide a sequence of values and it will return the smallest one.

String is a sequence of letters.

Letters are comparable according to ASCII (so you can do sorting). In ASCII table capital letters are first, so the 'T' is the smallest value.

ord(min(str(not()))) # 84

this just converts 'T' to Unicode value which is 84

range(ord(min(str(not())))) # range(0, 84)

This creates a sequence of numbers from 0 to 83

sum(range(ord(min(str(not()))))) # 3486

This works like min() except adds up all the numbers in the sequence together, so in our case 0+1+2+3+...+83 = 3486

chr(sum(range(ord(min(str(not())))))) # 'ඞ'

reverse of ord(), converts Unicode value to a character.

Why does not without a parameter return True? I'm starting to like the fact that I haven't touched python in a while.

[–] LostXOR@fedia.io 23 points 4 days ago (4 children)

I think it's because not() is equivalent to not(None), and since None is falsy not(None) returns True.

[–] takeda@lemm.ee 6 points 4 days ago (1 children)

Are you sure?

I can't test it now, but to me it looks like () is an empty tuple. Python behavior is that for logic operations empty set equals to false. Then we apply not to get True. Not having space between not operator and parentheses makes it look like it is a function.

[–] LostXOR@fedia.io 1 points 4 days ago

I'm pretty sure you're right; that makes more sense.

[–] Ziglin@lemmy.world 5 points 4 days ago (1 children)

Why is literally nothing equivalent to None? Is it because None is the default value of an optional parameter? (If so why oh why is it optional)

[–] spooky2092@lemmy.blahaj.zone 5 points 4 days ago* (last edited 4 days ago) (1 children)

Because nothing isn't something, and something is true. It's base Boolean logic where everything is either true or false. Null/nothing is false.

It's a weird way to think about conditionals, but it makes sense when you use them in real examples. In my case, I use them like this when I need to make sure that a variable has a value. So I can do something like

If(variable){do things with the variable}else{do stuff when the variable doesn't exist}

[–] Ziglin@lemmy.world 1 points 4 days ago (2 children)

I understand that, it makes sense. But why does it not throw an error? The parameter is missing after all.

[–] takeda@lemm.ee 2 points 3 days ago (1 children)

Actually the explanation is wrong.

not()

is actually

not ()

not is a keyword not a function.

Boolean of empty tuple is False and then not negates it.

I explained it better here:

[–] Ziglin@lemmy.world 1 points 3 days ago

That makes a lot more sense, thanks I did see in the syntax highlighting that it was a keyword but forgot that none of them took parameters.

[–] spooky2092@lemmy.blahaj.zone 0 points 4 days ago

No it's not, "" (a null/empty string) is the parameter. Not every function needs a parameter to be valid, and negation is one of them. Negating nothing is something, so "not()" = "not(null)" = "not(false)" = "true"

[–] brb@sh.itjust.works 5 points 4 days ago

God I love python

[–] humanspiral@lemmy.ca 2 points 4 days ago (1 children)

in J, many other languages, not null is null.

[–] pupbiru@aussie.zone 3 points 4 days ago
a  = null
if not a:
   …

if not a were null then an if that evaluates that would evaluate it as falsy… also if a would evaluate as falsy :/ that’s far weirder behaviour
