Python에서 한 목록을 다른 목록에서 효율적으로 빼는 방법은 무엇입니까?

<code class="python">[item for item in x if item not in y]</code>

<code class="python">list(set(x) - set(y))</code>

<code class="python">class MyList(list):
    ...
    def __sub__(self, other):
        ...</code>

<code class="python">x = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
y = [1, 3, 5, 7, 9]

# List Comprehension
result_comprehension = [item for item in x if item not in y]
print(result_comprehension)  # [0, 2, 4, 6, 8]

# Set Difference
result_set = list(set(x) - set(y))
print(result_set)  # [0, 2, 4, 6, 8]

# Custom Class
class MyList(list):
    ...
x_custom = MyList([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
y_custom = MyList([1, 3, 5, 7, 9])
result_custom = x_custom - y_custom 
print(result_custom)  # [0, 2, 4, 6, 8]</code>
