List comprehension

Question

What is benefit of using list comprehension?

Answer 1

Not having to do:
result = []
for each in something:
a = func(each)
result.append(a)

With a list comprehension, you just do:
result = [func(each) for each in something]

It also has the advantage of putting what is connected in the same logical line.

Answer 2

Shorthand writting... often more readable code ( but not always ^^ )
