Please follow up with good ways to write these. I hear that creating one
really good way is a Python maxim.
for item in alist:
print item
and
result = getResult()
For the later, the original weird form come from a C habit to allocate
returned structures within the caller and provide a pointer to it so the
function can fill the data in, otherwise the structure is lost as the
stack is popped out and the structure content is garbage. None of this
make any sense in python.
