Join permutations with newline fails

From

from itertools import permutations
perms = ['\n'.join(p) for p in permutations(['mac', 'hi', 'ne'])]
print(set(perms))

I get

{'hi\nne\nmac', 'hi\nmac\nne', 'ne\nmac\nhi', 'mac\nhi\nne', 'ne\nhi\nmac', 'mac\nne\nhi'}

And if I try

from itertools import permutations
perms = [''.join(p) for p in permutations(['mac', 'hi', 'ne'])]
print(set(perms), sep='\n')

I get

{'macnehi', 'nehimac', 'nemachi', 'machine', 'hinemac', 'himacne'}

My desired output should look like

macnehi
nehimac
nemachi
machine
hinemac
himacne

I don’t know what I’m messing. I’m appreciate any hints.

>Solution :

Expand the set:

print(*set(perms), sep='\n')

Or, join it explicitly:

print('\n'.join(set(perms)))
