How to initialize a two-dimensional array in Python?
A pattern that often came up in Python was
bar = for item in some_iterable: bar.append(SOME EXPRESSION)
which helped motivate the introduction of list comprehensions, which convert that snippet to
bar = [SOME EXPRESSION for item in some_iterable]
which is shorter and sometimes clearer. Usually you get in the habit of recognizing these and often replacing loops with comprehensions.
Your code follows this pattern twice
twod_list =  \ for i in range (0, 10): \ new =  \ can be replaced } this too for j in range (0, 10): } with a list / new.append(foo) / comprehension / twod_list.append(new) /
