python

Answer 3

simply put it is a way to make a list without having to input every item of the list.
you could define a list of even numbers like this:
evens = [0,2,4,6,8]
or you could use list comprehensions:
evens = [2*i for i in range(5)]

The second way comes in handy when lists are bigger or when for example the size of the list depends on input:

n = int(input())
evens = [2*i for i in range(n)]
