How can I get all of the bounds when the interval is not atomic?

Dear author，

Thank you for your excellent work! I have a question:

when the interval is not atomic, eg,

x = P.open(0, 1) | P.closed(3, 4)

I can use x.lower and x.upper get 0 and 4. Which attribute can I use to access 1 and 3?

Hello,

You can iterate on an interval to get access to the underlying atomic intervals:

>>> x = P.open(0, 1) | P.closed(3, 4)
>>> for i in x: 
       print(i.lower, i.upper)
0 1
3 4

To get them all at once, e.g. in a list, you can use list comprehensions, as usual:

>>> lower = [i.lower for i in x]
>>> upper = [i.upper for i in x]

Many thanks!
