snippet, python

i always get hung up on stupid shit. like, i didn't study my python docs or sicp today, i know. but how do i make this into one line? thx /prog/

        d0=fresult[1][0]-fresult[2][0]
        d1=fresult[1][1]-fresult[2][1]
        d2=fresult[1][2]-fresult[2][2]
        d3=fresult[1][3]-fresult[3][3]

d0, d1, d2, d3 = map(lambda n: fresult[1][n] - fresult[2 if n != 3 else 3][n], range(4))
python sucks tho

You shouldn't because Guido does not like functional constructs like map so you should use a loop instead.

Or you could stop using Python.

>>4
Can't use Haskell or LISP for everything you dunce.

>>5
Of course you can.

>>5
I don't use them for anything.

OP here, so what should i use, if not python? i heard algol was cool.

A list comprehension, actually.

Python is the best all-round language there is. There are some areas where it's weaker than some alternatives, but those alternatives tend to be much worse in other areas.

>>9
A list comprehension, actually.
A list comprehension is a loop.

As much as a map is. Stay out of the discussion if you don't understand it.

What discussion? This thread is an atrocity.

Since it's a language that prides itself on "readability", Python should provide better sugar for traversing things in parallel. It's not that uncommon.

d0, d1, d2, d3 = [a - b for (a, b) in zip(fresult[1], fresult[2])], assuming that last line is a typo.
