可以使用生成器表达式，通过zip并行迭代两个列表：

import bisect

class ComparableList:
    def __init__(self, x):
        self.list = x

    def __lt__(self, other):
        return all(x <= y for x, y in zip(self.list, other.list if isinstance(other, ComparableList) else other))

original_list = [[1, 1], [1, 2], [3, 3], [3, 4]]
insertion = [2, 2]

print(bisect.bisect_left(original_list, insertion, key=lambda x: ComparableList(x)))

这应该打印
