def bifurcate(lst, filter):
    print(lst)
    # [‘beep‘, ‘boop‘, ‘foo‘, ‘bar‘]

    print(filter)
    # [True, True, False, True]
    # 列表名,不是 filter 函数

    print(enumerate(lst))
    # <enumerate object at 0x0000017EB10B9D00>

    print(list(enumerate(lst)))
    # [(0, ‘beep‘), (1, ‘boop‘), (2, ‘foo‘), (3, ‘bar‘)]

    print([
    [x for i, x in enumerate(lst) if filter[i] == True],
    [x for i, x in enumerate(lst) if filter[i] == False]
    ])
    ‘‘‘
    filter[i] 主要是对枚举类型前面的索引和传入的 filter 列表进行判断是否重复
    ‘‘‘
bifurcate([‘beep‘, ‘boop‘, ‘foo‘, ‘bar‘], [True, True, False, True])
