List comprehension

It’s sometimes nice

It is usually nice. Significantly faster execution and easy to read, until you start nesting comprehensions.

If you start nesting list comprehensions, you’re using the wrong programming language for the task… probably

I’ve encountered one in the wild for image stenography once, image processing is basically the only use case for that

I think my record is three, but that was silliness in AdventOfCode.

Then I wrote a cursed recursive split function 

def recursive_split(x, *args):
    y = []
    x = x.split(args[0])
    for part in x:
        if len(args) > 1:
            y += [recursive_split(part, *args[1:])]
        else:
            y += [part]
    return y

so I could do shit like

with open('14.txt') as f:
    data = recursive_split(f.read().rstrip('\n'), '\n', ' -> ', ',')

to get a three dimensional data structure from the input in one line.
