用于动态过滤日期范围的代码

import datetime

def filter_dates(start_date, end_date, data):
    filtered_data = []
    for item in data:
        if start_date <= item['date'] <= end_date:
            filtered_data.append(item)
    return filtered_data

# 示例数据
data = [
    {'date': datetime.date(2022, 1, 1), 'value': 10},
    {'date': datetime.date(2022, 1, 2), 'value': 20},
    {'date': datetime.date(2022, 1, 3), 'value': 30},
    {'date': datetime.date(2022, 1, 4), 'value': 40},
    {'date': datetime.date(2022, 1, 5), 'value': 50},
]

# 设置过滤范围
start_date = datetime.date(2022, 1, 2)
end_date = datetime.date(2022, 1, 4)

# 过滤数据
filtered_data = filter_dates(start_date, end_date, data)

# 打印过滤结果
for item in filtered_data:
    print(item)
