TypeError: can't concat dict_keys to bytes

[ashimgiri000]

while querying i got these prompt

and if i add [list(oid_group)] instead of (oid_group.keys(),)

the output is in loop it doesn't break

[gescheit]

Could you please provide code which triggers error?

request you to check once

whenever i entered bad hosts it returns

'tuple' object has no attribute 'remove'
