javascript - Why do HTML/SVG Coordinate 0,0 starts at top left corner? -

just wondering whats reasoning behind saying 0,0 top left corner in browser both html/svg? there advantage this?

it goes against conventional wisdom (classic geometry) y values become greater in value lower on screen.

because that's how css predates svg works.

in cases, such stand-alone svg documents or svg document fragments embedded (by reference or inline) within xml parent documents parent's layout determined css [css2] or xsl [xsl], initial viewport coordinate scheme (and hence initial user coordinate system) has origin @ top/left of viewport, positive x-axis pointing towards right, positive y-axis pointing down,

python - How to add an model instance to a django queryset? - it seems django queryset behaves somehow python list. but doesn't back upwards list's .append() method know. what want like: from my_django_app.models import mymodel queryset = mymodel.objects.none() queryset.append(mymodel.objects.first()) ## no list's .append() method! is there way add together model instance existing queryset? no. queryset representation of query - hence name - not arbitrary collection of instances. if need actual queryset rather list, seek accumulating ids of objects need , getting objects via __in query: list_of_ids = [] list_of_ids.append(my_id) ... queryset = mymodel.objects.filter(id__in=list_of_ids) this isn't efficient, though. python django
