Dont you challenge me

the power of tuples

How much C code do you think it took to give you that simplicity in python? 😂

Instead of additions you can
a = a xor b
b = a xor b
a = a xor b
It should be the more efficient way and it's quite obscure the first time you read it

Yeah Cython depends on both

Welcome to devRant!

Can do that in Ruby too!

Thats Python baby and ruby too

Python and Ruby will never be better than C because without C they would not exist however.... I use python to generate C code from an xml schema

@jonjo I doubt C would ever be such a horrible parent.

Surly it would want it's children to exceed and become the best they possibly could.

Why would C hold them back.

😁😁😁😁😁

@querellaMMXII speak brother speak that's the truth

@querellaMMXII you can not exceed something that you rely on to live... C is god

[b, a] = [a, b];

JavaScript is better than it used to be

(a,b) = (b,a) in swift

@m93mark hell of your xoring - mark it in asm xD

@m93mark Hacker's delight? That book it's full of beautiful ingenious hacks!

I believe the whole point isn't to use a "third party" piece of code.

I can write my own C function that'll just be
Swap(a, b);
Which is basically what the standard Python library did, and gave you it as a standard, but behind the scenes, it was very likely done the very same way it was done here in C.

@MrJDev @apex actually I saw it in my x86 assembly course cause the exchange op was too mainstream u.u

b =(a+b)-(b=a)

Can't you do this in most modern languages?

@m93mark Well, anyway, you should check out that book. I discovered it because I was solving a "bit counting" problem, so I went to Java source to see how they did it. There it was, a comment and a reference to the book and chapter that describes a way to do it, complexity time O(1), it's amazing.

@apex thanks I'll look into it

@m93mark it also prevents overflow :)

@m93mark I was about to comment the same

Who wants to write the Assembly generated from that python :D

I can't because I code in erlang

@B45i typo, right? I don't see the variable a getting the value set anywhere?
But nice oneliner. Shouldn't it be
a=(a+b)-(b=a)

@siljamicke ma bad, made a typo there.

(((((((((a,b) = (b,a))))))))))
Lisp here

@balambuc that is wrong on so many levels of parenths

I know the above was a joke but FYI this is the (common) lisp way of doing it

(cl-rotatef a b)

Actually...

In C++ you'd have to check whether the numbers won't overflow. Python doesn't give a fuck and handles arbitrarily large numbers.

why would you ever need to do that? I have never needed to do a value swap.

In js: [a,b] = [b,a]

@nicholai I beat you to it ;)

@Hedgepig noooo. Haha. Tbh the thread was tl;dr

@nicholai yeah definitely, you're forgiven :p

@m93mark that's clever. Makes total sense too if you think about it for a minute.

@BartBB no! Swap(&a, &b) :)
