Question

I want to extract last two field values from a variable of varying length. For example, consider the three values below:

fe80::e590:1001:7d11:1c7e

ff02::1:ff1f:fb6

fe80::7cbe:e61:f5ab:e62 ff02::1:ff1f:fb6

These three lines are of variable lengths. I want to extract only the last two field values if i split each line by delimiter :

That is, from the three lines, i want:

7d11, 1c7e

ff1f, fb6

ff1f, fb6

Can this be done using split()? I am not getting any ideas.

Answer 1

If s is the string containing the IPv6 address, use

s.split(":")[-2:]

to get the last two components. The split() method will return a list of all components, and the [-2:] will slice this list to return only the last two elements.
