ciscolib cdp output list printing support

[buran]

use string

is this ok?

well, that is a question only you can answer. Does it look like YOU want it?
for print you may use something like this, more pythonic

neighbours = [{'ip': '172.21.162.164', 'hostname': 'PUN-DIG-DIG-01-ONN-BR-BS-GL-01', 'remote_port': 'FastEthernet0/24', 'local_port': 'FastEthernet0/18'}, {'ip': '172.21.162.157', 'hostname': 'PUN-DIG-DIG-02-ONN-BR-BS-01', 'remote_port': 'FastEthernet0/24', 'local_port': 'FastEthernet0/15'}, {'ip': '172.21.162.71', 'hostname': 'PUN-DIG-DIG-01-ONN-BR-BS-70', 'remote_port': 'FastEthernet0/24', 'local_port': 'FastEthernet0/19'}, {'ip': '172.21.160.2', 'hostname': 'pu-dig-dig-r1-as01', 'remote_port': 'GigabitEthernet1/0/9', 'local_port': 'GigabitEthernet0/1'}]
my_ip = "172.21.160.3"
for item in neighbours:
    print('{my_ip}\t{ip}\t{hostname: <30}\t{remote_port}\t{local_port}'.format(my_ip=my_ip, **item))

or use some of the avalable packages for print tabular data:
