生成介于2个日期范围之间的周范围

import datetime

def generate_week_ranges(start_date, end_date):
    # 向后取整到最近的周起始日
    start_date -= datetime.timedelta(days=start_date.weekday())
    # 向前取整到最近的周结束日
    end_date += datetime.timedelta(days=6 - end_date.weekday())

    week_ranges = []
    current_date = start_date
    while current_date <= end_date:
        week_start = current_date
        week_end = current_date + datetime.timedelta(days=6)
        week_ranges.append((week_start, week_end))
        current_date += datetime.timedelta(days=7)

    return week_ranges

# 示例用法
start_date = datetime.date(2022, 1, 1)
end_date = datetime.date(2022, 12, 31)
weeks = generate_week_ranges(start_date, end_date)
for week_start, week_end in weeks:
    print(f"Week: {week_start} - {week_end}")
