📃 Task requirements.

Create a function def island_perimeter(grid): that returns the perimeter of the island described in grid:

• grid is a list of list of integers:
  • 0 represents water
  • 1 represents land
  • Each cell is square, with a side length of 1
  • Cells are connected horizontally/vertically (not diagonally).
  • grid is rectangular, with its width and height not exceeding 100
• The grid is completely surrounded by water
• There is only one island (or nothing).
• The island doesn’t have “lakes” (water inside that isn’t connected to the water surrounding the island).
