如何更改列表的索引？

def move_element(lst, i, j):
    # 将索引为i的元素移除并插入到索引为j的位置
    lst.insert(j, lst.pop(i))
    return lst

# 示例
my_list = [1, 2, 3, 4, 5]
move_element(my_list, 2, 0)  # 结果: [3, 1, 2, 4, 5]

def move_evens_to_front(lst):
    evens = [x for x in lst if x % 2 == 0]
    odds = [x for x in lst if x % 2 != 0]
    return evens + odds

# 示例
my_list = [1, 2, 3, 4, 5]
move_evens_to_front(my_list)  # 结果: [2, 4, 1, 3, 5]

def sort_by_index(lst):
    return sorted(lst, key=lambda x: x[1])

# 示例
my_list = [(1, 3), (2, 1), (3, 2)]
sort_by_index(my_list)  # 结果: [(2, 1), (3, 2), (1, 3)]
