Need help solving these 3 function in python 3.6

thank you

First - Some Definitions We define a Grid and a Gridstring. They are just 2D lists and strings with particular structure inside, but the names will be convenient in describing the purpose of the functions we need to write. Python doesn't know about these names, it's just our own convention. Grid: a list of lists of Booleans. We expect all inner lists to be the same length. The outer (first) dimension represents the rows (from top to bottom), and the inner lists represent the items in that row., from left to right. The boolean value represents if the current cell is alive: True means alive, False means dead. Grids are zero-indexed for both dimensions. No negative indexes are allowed for them; only use forboth din ensions. No negative mdeses are allowed for them,duly use zero and up as the indexes Examples: tiny-grid [[True, False], [True, True]] = o sample_grid - [[False, False, False, False, False, Flse, False, True, True, False], True, True, True, False, False]1
