[Tutor] IP sorting

[Karthik Gurumurthy]

this one is cool and so was danny's.
i have a question here though.

why do we need to convert to a tuple?

lot = [tuple(map(int, ip.split("."))) for ip in iplist]

is there any specific reason. Python does not know to sort a list of lists?

karthik.

Nice problem! Here is my solution (for Python 2.x)

iplist = [
          "195.168.1.123",
          "192.168.1.123",
          "192.168.1.111",
          "192.168.1.11",
          ]

lot = [tuple(map(int, ip.split("."))) for ip in iplist]
lot.sort()
iplist1 = [".".join(map(str, addr)) for addr in lot]

print iplist1
