It helps in the recognition if you have separation between
something like
turnDirection.LEFT
and
alignment.LEFT
They may be the same or different value for LEFT, but by grouping
them in a "descriptive context", it's easy to catch mistakes such as
paragraph.align(turnDirection.LEFT)
when what you want is
paragraph.align(alignment.LEFT)
and, as an added bonus, prevents name clashes such as
turnDirection.LEFT = 2
alignment.LEFT = 0
With the grab-bag o' constants, you have to use old-school
C-style in your modern name-space'd Python:
gboc.TURN_LEFT = 2
gboc.ALIGN_LEFT = 0
or even worse, you'd end up with cruftage where you have
gboc.LEFT = 2
gboc.ALIGN_LEFT = 0 #created a month later as needed
and then accidentally call
paragraph.align(gboc.LEFT)
when you mean
paragraph.align(gboc.ALIGN_LEFT)
This is what I understand the grandparent's post to be referring
to by "descriptive context".
