查找月份的时间范围，滚动到一年

import datetime

def get_month_time_range(year, month):
    # 获取该月的第一天和最后一天的日期
    first_day = datetime.date(year, month, 1)
    if month == 12:
        last_day = datetime.date(year + 1, 1, 1) - datetime.timedelta(days=1)
    else:
        last_day = datetime.date(year, month + 1, 1) - datetime.timedelta(days=1)
    
    # 设置时间范围的起始时间和结束时间
    start_time = datetime.datetime.combine(first_day, datetime.time.min)
    end_time = datetime.datetime.combine(last_day, datetime.time.max)
    
    return start_time, end_time

# 获取当前日期和时间
current_datetime = datetime.datetime.now()

# 提取当前日期的年份和月份
current_year = current_datetime.year
current_month = current_datetime.month

# 计算当前月份的时间范围
start_time, end_time = get_month_time_range(current_year, current_month)

# 滚动时间范围到一年
if current_month == 1:
    start_time -= datetime.timedelta(days=365)
else:
    start_time -= datetime.timedelta(days=current_month-1)

# 打印时间范围
print("时间范围：{} 到 {}".format(start_time, end_time))
