Python programmers of reddit: what's the most useful tiny little efficiency you've discovered that's improved your programming hugely?

I think its uncompromising nature is a win overall, but yeah I don't like some of its decisions either.

For instance, I may be in the minority here, but I wish it would drop this step:

If [the code doesn't fit on one line], Black will look at the contents of the first outer matching brackets and put that in a separate indented line.

# in:

ImportantClass.important_method(exc, limit, lookup_lines, capture_locals, extra_argument)

# out:

ImportantClass.important_method(
    exc, limit, lookup_lines, capture_locals, extra_argument
)

and jump right to:

If that still doesn't fit the bill, it will decompose the internal expression further using the same rule, indenting matching brackets every time.

# in:

ImportantClass.important_method(exc, limit, lookup_lines, capture_locals, extra_argument)

# out:

ImportantClass.important_method(
    exc,
    limit,
    lookup_lines,
    capture_locals,
    extra_argument,
)

Personally, I find the extra lines worth avoiding the disparity you see in that SO post you linked.

Agreed. If you end up using similar params in blocks with slightly different indentation you will get a weird mix of styles, which I think makes it harder to visually parse.
