Accessing nested dictionary values. Plistlib, Python 2.7

[buran]

OMG...
This sounds like you chasing your tail... You have info in a structured file and you will access it in order to create file in order to access it...

I'll have to attack this again later this evening when I get back from work... I think a solution is on the horizon

[williamlombard]

Well the chasing of the tail has paid off...

Outputting a text file and then re-imporing it was never something I was going to take seriously.

Tried this...

for y in candidates2: HDsize = y['_items'][0]['_items'][0]['size']

and magically it gave me back "500,11 GB". It does#t matter how many SATA drives there are.

Thank God for that "print_dict()" function and whereever it came from!!!

Accessing other Apple hardware info in Python is now a breeze. No more blinding feeling through a dict with a 'for' loop.

Thanks buran for at least getting me out of the shadows here.
