class Solution(object):
    def canPlaceFlowers(self, flowerbed, n):
        default_count = flowerbed.count(1)

        if flowerbed[0:2] == [0, 0]:
            flowerbed[0] = 1

        if flowerbed[-2:] == [0, 0]:
            flowerbed[-1] = 1

        if flowerbed == [0]:
            flowerbed = [1]    

        flowerbed_str = ''.join([str(x) for x in flowerbed])

        while '000' in flowerbed_str:
            flowerbed_str = flowerbed_str.replace('000','010')


        return flowerbed_str.replace('000','010').count('1') - default_count >= n
