【项目记录】6：实时时间及季度剩余时间

由于工作需要，换季剩余时间成为需要。tkinter界面上实时显示时间（每秒），花了自己不少时间摸索，最后实现了。

效果如图，代码后面给出，仅供参考。

实时时间显示

实现代码如下：

# 实时时间及换季维护剩余时长
def get_date():
    import datetime
    date_now = time.localtime(time.time())
    now_year = date_now[0]
    now_month = date_now[1]
    now_day = date_now[2]
    quarter = int((int(now_month) - 1) / 3) + 1  # print(quarter)  获取当前月份所在季度
    # 防止在每季度最后一天时，计算为负数，显示不正确，多取一天
    if quarter == 1:
        q1_deadline = datetime.date(now_year, 4, 1)
        q1_time = str(q1_deadline.strftime('%Y-%m-%d'))
        return q1_time
    elif quarter == 2:
        q2_deadline = datetime.date(now_year, 7, 1)
        q2_time = str(q2_deadline.strftime('%Y-%m-%d'))
        return q2_time
    elif quarter == 3:
        q3_deadline = datetime.date(now_year, 10, 1)
        q3_time = str(q3_deadline.strftime('%Y-%m-%d'))
        return q3_time
    elif quarter == 4:
        q4_deadline = datetime.date(now_year+1, 1, 1)  #第二年的1月1日00：00
        q4_time = str(q4_deadline.strftime('%Y-%m-%d'))
        return q4_time
    #如2022年第四季度，则返回2023-01-01

ticks = time.localtime(time.time())
# print(ticks)  获取当前时间time.struct_time(tm_year=2022, tm_mon=1, tm_mday=1, tm_hour=1, tm_min=1, tm_sec=1, tm_wday=1, tm_yday=1, tm_isdst=0)
now_year = ticks[0]
now_month = ticks[1]
now_quarter = int((int(now_month) - 1) / 3) + 1
# print("现在是第%s年" % now_year,"现在是第%s月" % now_month,ticks[2], "现在是第%s季度" % now_quarter)

# print(deadline)

    now_time_s = str(time.strftime('%Y-%m-%d'))
    # print(now_time,now_time_s,time.localtime(now_time))  #time.struct_time(tm_year=2022, tm_mon=9, tm_mday=30, tm_hour=11, tm_min=48, tm_sec=46, tm_wday=4, tm_yday=273, tm_isdst=0)
    aid_date = datetime.datetime.strptime(s, "%Y-%m-%d")
    #print(aid_date)  #2022三季度2022-09-30 00:00:00
    aid_time = int(time.mktime(aid_date.timetuple()))  # 转化为时间戳
