Cause for using objects?

[John Heasly]

Given:
[{"mugshot": "nw_gradspeaker4_0608", "width": 67.0, "height": 96.0}, \
{"mugshot": "nw_gradspeaker2_0608", "width": 67.0, "height": 96.0}, \
{"freehand": "b1.developreport.0614", "width": 154.0, "height":
210.0}, \
{"graphic": "bz_cafeparadiso_0613", "width": 493.0, "height": 341.0}]

Return:
{"mugshot1": "nw_gradspeaker4_0608", "mugshot1.width": 67.0,
"mugshot1.height": 96.0,\
"mugshot2": "nw_gradspeaker2_0608", "mugshot2.width": 67.0,
"mugshot2.height": 96.0, \
"freehand1": "b1.developreport.0614", "freehand1.width": 154.0,
"freehand1.width": 210.0, \
"graphic1": "bz_cafeparadiso_0613", "graphic1.width": 493.0,
"graphic1.height": 341.0}

I'm trying to teach myself some OOP. Does grinding the Given above into
the Return seem like a good candidate?

If that's all you're doing, and you must use that output format, then
I'd say no. OOP is not a panacea.

Now if you're going to *do* something with the return information, then
I would say yes. But in that case, don't use a single dict as a return,
use objects.

If your table of photo data has several types of photos, and you find
yourself saying

if is_mugshot:
#something
elif is_freehand:
#something
else:
#something

then OOP will help organize your code.
If it's just a flat table of data, and you lay down a deeply nested
hierarchy of stuff, you may have over-engineered.
Best,
