在python中过滤偶数个月和月底的一系列日期

import datetime

def filter_dates(dates):
    filtered_dates = []
    for date in dates:
        if date.month % 2 == 0 and (date + datetime.timedelta(days=1)).day == 1:
            filtered_dates.append(date)
    return filtered_dates

# 示例日期列表
dates = [datetime.date(2022, 1, 31), datetime.date(2022, 2, 28), datetime.date(2022, 3, 31), datetime.date(2022, 4, 30)]

# 过滤偶数个月和月底的日期
filtered_dates = filter_dates(dates)

# 打印结果
for date in filtered_dates:
    print(date)
