Convert a string into a two-dimensional array in Python

Question

So I was trying to do a maze and wanted to transform the maze into a two-dimensional array so it would be easier to manipulate, but I didn't really succeed. The best I've done is a list of string with the following :

map = """
OOOOOOOOOO
O O    O O
O . OO   O
O O O   XO
O OOOO O.O
O O O    U
O OOOOOO.O
O O      O
O O OOOOOO
O . O    O
OOOOOOOOOO
"""
map = [i for i in map.splitlines()]

Thanks for the help

Just an FYI, with your map string as it's currently written, you'll have an empty list at position 0 (since multi-line strings preserve all newlines). If you don't want this, you can add a \` to skip the first newline -> map = """\` — b_c

splitlines() returns a list of strings. Each string being a line.

So when you call it on your example, it returns a list of strings. If you want a list of lists, you must convert each string to a list. This can be done easily with the list() function :

map = [list(line) for line in map.splitlines()]
