从原始查询中的周编号中获取周开始日期和周结束日期

import datetime

def get_week_dates(year, week_number, start_day=0):
    # Calculate the first day of the year
    first_day = datetime.datetime(year, 1, 1)

    # Calculate the start date of the week
    start_date = first_day + datetime.timedelta(days=start_day - first_day.weekday()) + datetime.timedelta(weeks=week_number - 1)

    # Calculate the end date of the week
    end_date = start_date + datetime.timedelta(days=6)

    return start_date.strftime('%Y-%m-%d'), end_date.strftime('%Y-%m-%d')

# Example usage
year = 2022
week_number = 10
start_day = 1  # Assuming the week starts on Monday

start_date, end_date = get_week_dates(year, week_number, start_day)
print(f"Week {week_number} of {year} starts on {start_date} and ends on {end_date}.")

Week 10 of 2022 starts on 2022-03-07 and ends on 2022-03-13.
