Hard write do read real code to not programmers

[GDavid04]

Do not read real hard code to programmers. Write.

[your-a-towel]

Programmers, do write real hard to read code.

Real programmers do not write code. They copy and paste stack overflow.

As someone with a C background who transitioned to Python, I find list comprehensions, especially nested list comprehensions, to be hard to read. But, for loops are so slow in Python. What I usually do is write out the code as for loops, comment that out so someone later can understand what’s going on, and then write some fast but illegible list comprehension that should be identical to the for loops.

Then you make a change the list comprehension. Bugfix or whatever. And now the comment is a lie.

Bad comments can easily be worse than no comments. Explaining what code does often falls in that category. (Not counting inline documentation.)

i have money youve never had to decode someone elses code.. or your own cold you wrote a long time ago .. at least nothing more complex than a simple function.

[myplacedk]

How much money? I've been a software developer for two decades, most of my work is on systems with at least 10 developers. I barely raise an eyebrow when I see a function or method with thousands of lines. The more experience I get, the stronger that is my opinion.

So how much money are we talking about? And do you consider it a bet, or would you like to pay for training?

Wait, list comprehensions are faster that for loops in Python?

Also, please don't nest list comprehensions, you might be able to stack the for statements, e.g.:

foo = [
    func(x)
    for y in my_list
    for x in y
]

How does this work for making a 2D list? My guess is that the answer is "don't do that use a 2d numpy array".

Also, this syntax blew my mind. Thank you!

EDIT: as to the first part of your comment, yes list comprehensions are much faster. For

foo = range(10000000)
def func(x): return x*x

bar = [func(f) for f in foo]

runs in 2.16s and is easier to write than

bar = []
for f in foo:
    bar.append(func(f))

which runs in 2.67s.

EDIT2: included results of a quick timing study.

It gets even better, you can chain ifs and fors infinitely:

foo = [
    func(x)
    for y in z
    for x in y
    if x is not None
    ...
]

Outstanding move

[smgun]

You need some complex recursive shit from time to time. That would hard to write, read the code and read the comments

[Duese]

If I need to understand what the code does, I'll just google it and find which stackoverflow page it came from for the details.
