This would have worked if you sorted your lists first -

>>> [i for i, j in zip(sorted(teams), sorted(shuffle_teams)) if i != j]
[('Ally', 2), ('Fredricka', 3), ('Tim', 1)]

Except you wanted to see the results from shuffle_teams, so instead of
'i for i, j ...', use 'j for i, j ...' -

>>> [j for i, j in zip(sorted(teams), sorted(shuffle_teams)) if i != j]
[('Ally', 3), ('Fredricka', 1), ('Tim', 2)]
