| symmetric_difference | list,beginner |
Returns the symmetric difference between two iterables, without filtering out duplicate values.
- Create a
setfrom each list, then use list comprehension on each one to only keep values not contained in the previously created set of the other.
def symmetric_difference(a, b):
_a, _b = set(a), set(b)
return [item for item in a if item not in _b] + [item for item in b if item not in _a]
symmetric_difference([1, 2, 3], [1, 2, 4]) # [3, 4]
