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!
Other answers have been good; to them I'll add the comment that list
comprehensions are for *constructing* lists, not manipulating the
elements thereof.
