Hi,
I'm just reading Robert M. Martin's book entitled "Clean Code". In Ch.
5 he says that a function that is called should be below a function
that does the calling. This creates a nice flow down from top to
bottom.
I prefer to define my terms before I use them. Classes, functions, etc
get defined at the top and called down below. It's a stylistic thing,
but it ties in with what you would do in a debate or scholarly
document; and if you're skimming such a document and you don't
understand a term, you know to scan upwards for its definition.
It's just a stylistic thing, you can do it whichever way you think best!
You also need to remember that in Python, function and class
definitions are _not_ declarations, but statements which have the
effect of adding a name to the namespace.
If you try to call a function before the flow of control has seen the
function definition, you'll get a NameError.
