So here's a completely contrived example, but say for instance that
the BK api let you post a note and a photo in one request ( I'm pretty
sure it doesn't, so don't try it, but bear with me for the sake of
argument) and both objects had a 'body' parameter. If you wanted to
do that you could send a request like
note[body]=someNote&photo[body]=somepic.jpg and you could tell pretty
easily which 'body' was which.
Not sure about the python world, but this is pretty common among Rails
apps, since Rails automagically unrolls the request parameters into a
hash-like object and understands the [] structure. No reason you
couldn't do the same thing in python, it's not language specific
although it's nice if the framework you have can do the work for you
so you don't have to write some code to parse the []'s yourself.
