question about class, functions and scope

lo there all,

i have an app that runs three classes as threads in the same program.
some of them need to be able to share some functions. Can i set a
function before i define a class and have the class use it ? Kinda like
this.

def some_function(var1, var2):
do something with var1, var2
return result

class do_something1(threading.Thread):
def __init__(var):
do something
def run():
var1 = 3
var2 = 4
result = some_function(var1,var2)

is this legal ? is it pythonic?
i ask because i plan to do a big re-write soon, and want to get rid of
some repetition

thanks

nephish:It's legan and pythonic. Functions are here for a purpose.

the functions defined above the classes that the could be called from
within the classes, they do not need a 'self' declaration because they
are not part of a class, right?

re: question about class, functions and scope

nephish:Class methods generally require the self as first parameter, functions
don't need the self. So your original code was wrong (sorry, I haven't
seen that before).

You can also inject functions as methods inside a class, and in such
case your function usually needs a self parameter too.

It's ok - but beware of concurrency problems. By example, two threads
trying to update the same thing. (Doesn't happen in your small example).

That really depends on your design. Python does not enforce that
*all* code be in class methods; using functions alone -as others have
pointed out- is fine.
