给定开始日期和结束日期，最有效的方法是生成介于两者之间的所有周吗？

import datetime

def generate_weeks(start_date, end_date):
    weeks = []
    current_date = start_date
    
    while current_date <= end_date:
        week_start = current_date - datetime.timedelta(days=current_date.weekday())
        week_end = week_start + datetime.timedelta(days=6)
        weeks.append((week_start, week_end))
        current_date += datetime.timedelta(days=7)
    
    return weeks

# 示例使用
start_date = datetime.date(2022, 1, 1)
end_date = datetime.date(2022, 12, 31)
weeks = generate_weeks(start_date, end_date)

for week_start, week_end in weeks:
    print(f"Week: {week_start} - {week_end}")
