如何循环几周并找到某些日期的确切日期？

import datetime

def find_exact_dates(start_date, num_weeks, target_day):
    dates = []
    current_date = start_date

    for _ in range(num_weeks):
        end_date = current_date + datetime.timedelta(days=6)  # 计算每周的结束日期
        if end_date.day == target_day:  # 判断结束日期是否满足条件
            dates.append(end_date)
        current_date = end_date + datetime.timedelta(days=1)  # 更新当前日期为下一周的起始日期

    return dates

start_date = datetime.datetime(2022, 1, 1)  # 设置起始日期
num_weeks = 10  # 设置循环的周数
target_day = 15  # 设置目标日期为每周的第15天

result = find_exact_dates(start_date, num_weeks, target_day)
for date in result:
    print(date.strftime("%Y-%m-%d"))  # 打印满足条件的日期
