Generate lists of devices and partitions from /proc/partitions?

[DachshundDigital]

Generate list of devices and partitions, which includes blocks and names, from /proc/partitions?

For example this...

# cat /proc/partitions
179 0 30976000 mmcblk0
179 1 262144 mmcblk0p1
179 2 30709760 mmcblk0p2
8 0 156290904 sda
8 1 156289880 sda1

Resulting in this...
Disks: [(30976000, mmcblk0), (156290904, sda)]
Partitions: [(262144, mmcblk0p1), (30709760, mmcblk0p2), (156289880, sda1)]

Sounds like a homework assignment.

The trick is that /proc/partitions uses whitespace to look somewhat like a table. You cannot use split(' ') because that would give you something like this (based on running this code on my PC):

Output:
['8', '', '', '', '', '', '', '', '0', '', '', '39080664', 'sda']
['8', '', '', '', '', '', '', '', '1', '', '', '', '', '524288', 'sda1']
['8', '', '', '', '', '', '', '', '2', '', '', '38555335', 'sda2']

So you either need to remove the extra whitespace or find a way to treat multiple blanks as one. I think I remember there being a re.split() where you can specify a regex pattern. I would start looking there.
