Assign random to several values at a time

I'm trying to get used to list comprehensions, but I struggle with this- How can I assign random integers to several values at a time?

My solution is this:

a,b,c=random.sample(100, 3)

But when I run code it gives me error:

TypeError: Population must be a sequence or set.  For dicts, use list(d).

I think there shoud be solution to avoid simply repeating this three times like:

a=random.randint(0,99)
b=random.randint(0,99)
c=random.randint(0,99)
