Initialize 2D list
Initializes a 2D list of given width and height and value.
- Use a list comprehension and
range()to generatehrows where each is a list with lengthh, initialized withval. - Omit the last argument,
val, to set the default value toNone.
def initialize_2d_list(w, h, val = None): return [[val for x in range(w)] for y in range(h)] initialize_2d_list(2, 2, 0) # [[0, 0], [0, 0]]
