如何在Python中拆分列表元素

def split_list(lst, n):
    """将列表lst均匀地分割成n个子列表"""
    k, m = divmod(len(lst), n)
    return [lst[i*k+min(i, m):(i+1)*k+min(i+1, m)] for i in range(n)]

# 示例
my_list = [1, 2, 3, 4, 5, 6, 7, 8, 9]
sublists = split_list(my_list, 3)
print(sublists)  # 输出: [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

def split_elements(lst, delimiter):
    """将列表lst中的每个元素按delimiter拆分"""
    return [item.split(delimiter) for item in lst]

# 示例
my_list = ["apple,banana", "orange,grape", "kiwi,mango"]
split_result = split_elements(my_list, ",")
print(split_result)  # 输出: [['apple', 'banana'], ['orange', 'grape'], ['kiwi', 'mango']]

import itertools

def split_list_iterative(lst, n):
    """使用itertools将列表lst均匀地分割成n个子列表"""
    it = iter(lst)
    size = len(lst) // n
    remainder = len(lst) % n
    return [list(itertools.islice(it, size + (i < remainder))) for i in range(n)]

# 示例
my_list = [1, 2, 3, 4, 5, 6, 7, 8, 9]
sublists = split_list_iterative(my_list, 3)
print(sublists)  # 输出: [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
