如何在python中基于regex过滤列表项？

import re

def filter_list_items(pattern, items):
    filtered_items = []
    for item in items:
        if re.search(pattern, item):
            filtered_items.append(item)
    return filtered_items

# 示例使用
items = ['apple', 'banana', 'cherry', 'date', 'grape']
pattern = r'a.*'  # 匹配以字母'a'开头的项
filtered_items = filter_list_items(pattern, items)
print(filtered_items)
