Conky ignores Tabs

[hollysheep]

With the application "fritzconnection" (written in Python) i can read all hosts connected to my router (FritzBox 7490). This is the line in the conky config file:

${execi 5 python3 python.py}

The output looks like

192.168.10.21 host1
192.168.10.22 host2
192.168.10.23 host3

As you can see there is a normal space between the IP and the hosts name. When the IP is 192.168.10.101 the output is

192.168.10.21 host1
192.168.10.22 host2
192.168.10.101 host3

As you can see the h of host3 is father to the right then the others. When i replace the space with a tab ("\t") the output looks terrible:

192.168.10.21        host1
192.168.10.22    host2
192.168.10.101    host3

It seems the tab is completely ignored by conky.

What i want is the first but also with longer IPs.

EDIT
This is the python script, perhaps the problem is here?
from fritzconnection.lib.fritzhosts import FritzHosts

fh = FritzHosts(address='192.168.10.1')
hosts = fh.get_active_hosts()
for index, host in enumerate(hosts, start=1):
	ip = host['ip'] if host['ip'] else '-'
	hn = host['name']
	print(f'{ip:<16} {hn:<28}')

I found the script in the web. I don't know what "{ip:<16}" is doing.
