I cannot figure out how to specify a list of a particular size.
For example, I want to construct a list of size 10, how do I do this?
A list does not have a fixed size (as you probably know)
But you can initialize it with 10 somethings > >>> [None]*10 [None, None, None, None, None, None, None, None, None, None] >>> range(10) [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] >>>
Also, list comprehensions may be useful if you have mutable objects:
[{} for _ in range(10)]And to see why [{}]*10 is probably not what you want:py> lst = [{}]*10
py> lst[0][1] = 2
py> lst
[{1: 2}, {1: 2}, {1: 2}, {1: 2}, {1: 2}, {1: 2}, {1: 2}, {1: 2}, {1: 2}, {1: 2}]
py> lst = [{} for _ in range(10)]
py> lst[0][1] = 2
py> lst
[{1: 2}, {}, {}, {}, {}, {}, {}, {}, {}, {}]
