Python Script to convert firewall rules

[Kashif Rana]

Hi Jason

Thank you very much. Appreciated ! But the first requirement was to convert
format1 to format2 as below:

set interface ethernet2/5 ip 10.17.10.1/24 (format 1)
set interfaces ge-0/0/0 unit 0 family inet address 10.17.10.1/24 (format 2)
(set, interface, ip) = (set, interfaces, family inet address)
But some values are variable and should ask the user to convert manually
like ethernet2/5 equal to ge-0/0/0 or ge-0/0/1 or ge-0/0/2
And some values keep as it is like 10.17.10.1/24

Thanks and Regards,

Kashif
