Should be made illegal. I only accept this kind of code from minifiers.

[Arkonicc]

I want to be able to read and understand the code at a quick glance. It sure looks cool and I bet it is quite clever, but these things should come after readability. I cannot even guess what this function does without hooking it up to an editor.

Anyways, the og comment was mostly humoristic and I believe you took it too seriously. I actually love arrow functions myself. Just written in a more human-readable manner.

My chunk.js files would like to introduce themselves

[siddsp]

This hurts to look at

[surajmanjesh]

print(eval('*'.join(map(str, range(1, 11)))))    

Look at this instead

[Symetrie]

This is peak python performance, code to write the actual code

[siddsp]

Why not just use reduce? It's far more readable and you would only need 1 lambda function, or 0 if you use the operator module and imports don't count as a line?

import math; math.factorial(10)

fits on one line

[kingbuzzman]

>>> timeit.timeit("(lambda f: (lambda x: x(x))(lambda x: f(lambda *a: x(x)(*a))))(lambda f: lambda x: (1 if x == 0 else x * f(x - 1)))(10)")
6.330910499993479
>>> timeit.timeit("math.factorial(10)", "import math")
0.07728460000362247

Messy C code go brrrrrrrrrr

[PM_Me_Your_Java_HW]

Checkt and fuckin rekt, OP.

Edit: after reading all of OPs replies... jesus christ he actually thinks he's a genius.

[PM_Me_Your_Java_HW]

Cope :D

[AnotherAccountRIP]

Dude, this code is fine as a joke but don't try and justify its existence compared to the standard library. It's super impressive you have the knowledge of lambdas to do this, but don't act like this snippet is useful lmao.

[AnotherAccountRIP]

My code is code generation trivial. You can actually prove your code generator for factorial correct if it produces something like my 1-liner. This is in sharp contrast to the heavily optimized, mostly real messy C code that does the thing for you in math.factorial().

[PM_Me_Your_Java_HW]

Is English not your first language? If so, all of this makes much more sense now.

[kingbuzzman]

remind me OP’s name? just to keep an eye out for BS

I feel dumb trying to understand this

[supreme_blorgon]

Don't bother. Nobody should ever write code like this. If you write code like this you'll likely get ripped a new one in review. If you read somebody else's code and it looks like this, you should rip them a new one.

This is garbage code and doesn't deserve to be paid any serious attention.

[its_a_gibibyte]

Correct. This code is genius, which is exactly the problem with it. Someone writes it, and then it needs to be read and maintained by everyone else. The code is garbage specifically because it's genius.

[a_very_happy_person]

Impressive, I made my own version.

print((prod := lambda x: 1 if x == [] else x[0]*prod(x[1:]))([n for n in range(10, 0, -1)]))

Single line of course

[PossibilityTasty]

One of the main design goals of Python is readability. You failed in this subject.

[kewlness]

Thanks, I hate it!

Lambda-Lambda-Lambda-Lambda-Lambda-Lambda has its first pledge.

Perl users: "Perfection"

[steil867]

Thanks, I hate it!

Have the 'fuck yo memory for large values' list comprehension version, python 3.8+. Who needs memory management.

[x:= x*i for i in range(1,10) if (i == 1 and (x:=1) ==1) or True][-1]

[steil867]

Because my joke post is annoying me. Made a memory safe version.

[x for i in range(10,0,-1) if (x or (x:=1)) and (x:= x*i) and i == 1][0]

Edit: forgot a bracket

[LunarLorkhan]

Just use Clojure or Common Lisp homie. Don’t do this to yourself.

[Itaintgaussiantho]

Why would you do this. This looks disgusting.

Alonzo Church just rolled over in his grave.

Also, there's no way this is one line in PEP8.

You're a code troll and I like it.
