certainly not!
there are many things wrong with that.
first of all, as was pointed out already: this is highly un-pythonic.
secondly, its completely wrong. if you bind 'buffer' to another object,
then you have no chance of modifying its original contents. thats why i
stated in my previous post that IF you insist on persuing the
"un-pythonic" path then your function argument 'buffer' _must_ be a
mutable object which you must operate on through its methods, but you
CANNOT modify it with: buffer=data.
doing that will only re-bind 'buffer', it will never change anything
outside the function.
