Do all class need constructors?(__init__)

[hsunteik]

I know it is all up to the programmer,but do most programmer do 
like this:

class test():
    def say(message):
        print (message)
test.say('hello')

or,like this:

class test():
    def __init__(self,message):
        self.message=message
    def say(self):
        print(self.message)

newtest=test('hello')
newtest.say()

i think using constructor is better,because i can instanciate an object to create multiple copy of the object with just one class.
what do you all think?
which is better?
