Hi Expert,
I am learning python to do some system admin code, i am still in the
process of learning but I need a help on bellow code in urgent, i will be
really greatfull for any help

Basically i wanted like this :-

grep a line which has 1:0:0:129 , and get the LUN number(i.e
360060165656565634348a739e511) for this path

so the Dictionalry will be :

dict = {'360060165656565634348a739e511': '1:0:0:129',
'3600601323h42h2k323asdf33511': 1:0:2:98};
