Two: [56, 57, "dog"] and [] (empty).

What do you mean by “spaces”, exactly?

alist contains:
0. the integer 3
1. the integer 67
2. the string "cat" ¹
3. the list:
0. the integer 56
1. the integer 57
2. the string "dog" ¹
4. an empty list
5. the float 3.14
6. the boolean False

There are two lists in x, and one more list inside a list inside of x:
> x = ['a', [2.0, 5, [10, 20]]]
x contains:
0. the string 'a'
1. the list:
0. the float 2.0
1. the integer 5
2. the list:
0. the integer 10
1. the integer 20
