Defining multiple objects of the same class in python

is there any short开发者_开发百科hand method of defining multiple objects of the same class in one line. (I'm not talking about lists or array of objects)..

i mean something like

p1,p2,p3 = Point()

any suggestions?

It may be slightly more efficient to use a generator comprehension rather than a list comprehension:

p1, p2, p3 = (Point() for _ in range(3)) # use xrange() in versions of Python where range() does not return an iterator for more efficiency

There's also the simple solution of

p1, p2, p3 = Point(), Point(), Point()

Which takes advantage of implicit tuple packing and unpacking.

Not really.

p1, p2, p3 = [Point() for x in range(3)]

What exactly are you trying to achieve?

This code does what you're asking, but I don't know if this is your final goal:

p1, p2, p3 = [Point() for _ in range(3)]

Think map is also acceptable here:

p1, p2, p3 = map(lambda x: Point(), xrange(3))

But generator expression seems to be a bit faster:

p1, p2, p3 = (Point() for x in xrange(3))
