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

# 假设我们有一个包含字符串的列表，我们想要将每个字符串按空格拆分
strings = ["hello world", "foo bar", "baz qux"]
split_strings = [s.split() for s in strings]
print(split_strings)  # 输出: [['hello', 'world'], ['foo', 'bar'], ['baz', 'qux']]

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)
    return [list(itertools.islice(it, i)) for i in range(n)]

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