Use symbolic operator names (moveto, lineto) in contour_manual example.

[anntzer]

It's clearer to directly use the names (or their one-letter abbreviations M/L, which are e.g. part of the svg standard) that using numeric values and then explaining the numeric values.

Take or leave my remark.

[timhoffm]

While at it, I would go a bit more verbose:

Suggested change

	M = Path.MOVETO
	L = Path.LINETO
	kinds01 = [[M, L, L, L, M, L, L, L]]
	MOVE = Path.MOVETO
	LINE = Path.LINETO
	kinds01 = [[MOVE, LINE, LINE, LINE, MOVE, LINE, LINE, LINE]]

or even

steps = [
    (Path.MOVETO, [0, 0]),
    (Path.LINETO, [3, 0]),
    (Path.LINETO, [3, 3]),
    (Path.LINETO, [0, 3]),
    (Path.MOVETO, [1, 1]),
    (Path.LINETO, [1, 2]),
    (Path.LINETO, [2, 2]),
    (Path.LINETO, [3, 1]),
]

fills, kinds = zip(*steps)

But the proposal is also ok if you don't want to do more.

I don't think long names really help readability here; the point is really to see that there's 1 M followed by 3 Ls, twice.

[oscargus]

I think that some way to "visually" connect the code and the points would be nice, but I am not really sure the zip-thing is worth it. So may just keep it as is.

[oscargus]

I think the import ordering was decided to keep plt separate. Also, this is not really in alphabetical order anymore (which lead me to check the pre-commit and it is indeed failing...).

[anntzer]

fixed

[timhoffm]

Let’s take it as is.
