quick beginners List comprehension question

[Dr Mephesto]

Hi,
Im new to python, and OOP, and am trying to get a handle on list
comprehension.

Say I have a class Foo with a property called bar:

class Foo:
    def __init__(self):
        self.bar = random.randint(1,100)

and then I make a list of these objects:

Newlist = []
for x in range(10):
    Newlist.append(Foo())

Now, suppose I wanted to triple the value of 'bar', I could always do:

for x in range(10):
	Newlist[x].bar = Newlist[x].bar * 3

but can I do this using list comprehension?  Thanks in Advance!
