HERES MINE:

import sys

class Cursed(type):
def new(cls, name, bases, attrs):
sys.stdout.write("".join(map(chr, [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100, 10])))
return super().new(cls, name, bases, attrs)

class _(import("builtins").object, metaclass=Cursed):
pass

def cursed_decorator(f):
exec("print('hello world')")
return lambda: None

@cursed_decorator
def totally_normal_function():
print("hello world")

(eval("import('builtins').exec"))("print('hello world')")

import types
bc = compile("print('hello world')", "", "exec")
types.FunctionType(bc, {}).call()

Here is my cursed code to print "hello world":

def hello_world():
    import functools
    import operator
    global the_most_peculiar_global_variable
    def a_function_that_does_almost_nothing():
        def another_incredibly_boring_function(input_parameter_x):
            return input_parameter_x
        return another_incredibly_boring_function
    the_most_peculiar_global_variable = a_function_that_does_almost_nothing()
    a_list_of_random_things = list()
    for a_totally_arbitrary_number in (0x68, 0x65, 0x6C, 0x6C, 0x6F, 0x20, 0x77, 0x6F, 0x72, 0x6C, 0x64):
        exec(f"a_list_of_random_things.append(chr(a_totally_arbitrary_number))")
    def a_function_that_combines_things_together(a_list_of_items):
        def a_sub_function_that_adds_items(item_a, item_b):
            return item_a + item_b
        a_resulting_amalgamation = functools.reduce(a_sub_function_that_adds_items, a_list_of_items, "")
        return a_resulting_amalgamation
    result = the_most_peculiar_global_variable((lambda an_input_list: a_function_that_combines_things_together(an_input_list))(a_list_of_random_things))
    return result

Enjoy ! :)

Nearly. Right idea though

Hi.
I'm surprised by these two test cases that seem to contradict each other:
fn x => 0 must raise an error according to the button test,
fn one => 1 must be a valid function with no arguments and always return 1 according to the attempt.

In my opinion the first test case means 'a function must have a name' but in that case x could be considered to be the name of a function..

Should the test case be modified?
How did you managed this?
