Dumb newbie question

[mlieqo]

it's called list comprehension - https://docs.python.org/3/tutorial/datas...rehensions and you could write it like this:

class Polygon:
    def __init__(self, no_of_sides):
        self.n = no_of_sides
        self.sides = []
        for i in range(no_of_sides):
            self.sides.append(0)

it will create a list and append a 0 for every side, so let's say:

p = Polygon(no_of_sides=3)
print(p.sides)

then

Output:
[0, 0, 0]
