Why does the first range convert to a list, but not the second?
p = list(range(1,20)), (range(40,59))
p
([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19],
range(40, 59))
I'm not sure I understand correctly. This is what the top of help(range)
says:
<
Help on class range in module builtins:
class range(object)
| range(stop) -> range object
| range(start, stop[, step]) -> range object
|
| Return a virtual sequence of numbers from start to stop by step.

So range() returns a range object. In your example you convert the first
one to a list with list(), but not the second, so it prints the range
object.
>>> range(2)
range(0, 2)
>>> list(range(2))
[0, 1]
