如何自动重新加载我的输出?

How can I automatically reload my output?

我想从日期、月份和年份进行计数,我想在带有 raspberry pi 或类似内容的小屏幕上显示计数。我如何生成循环等以更新屏幕上的数字(例如每小时)?

这是我写的代码:

import time

now = time.localtime()
day=now.tm_mday
month=now.tm_mon
year=now.tm_year
hour=now.tm_hour
minute=now.tm_min
summer=now.tm_isdst
print("Tag:", day)
print("Monat:", month)
print("Jahr:", year)



if month<4:
    j=year-2020
elif month==4:
    if day<4:
        j=year-2020
    else:
        j=year-2019
else:
    j=year-2019


if month<4:
    m=month+7
elif month==4:
    if day<7:
        m=month+7
    elif day>=7:
        m=0
    else:
        m=month-4
else:
    m=month-4




if day<7:
    t=day+24
elif day==7:
    t=0
else:
    t=day-7
print(j , ":" , m , ":" , t) 

定时器应该从 2020 年 4 月 7 日开始工作。

这个循环工作得很好......

from datetime import datetime                              # for managing dates and times
import time                                                # for sleeping
while True:                                                # Just loop forever
    time.sleep(0.0)                                        # Set this to modify the tick rate
    d = datetime.now()                                     # Update time
    print(d.strftime("%A %d. %B %Y %H:%M:%S.%f"),end="\r") # Print time

如果您对 strftime 感到困惑,请查看此处的格式占位符:https://strftime.org/

因此,我将您发送给我的代码放入了我的项目中,并且运行良好。我的下一步是将数字(年、月、日)放在 window 或类似的东西中,以在带有 raspberry pi 的屏幕上显示计数器。那么,如何在不关闭 window 的情况下打开一个显示计数器并每小时更新一次的 window?

到目前为止,这是我的代码:

import time

now = time.localtime()
hour=now.tm_hour
minute=now.tm_min
summer=now.tm_isdst
#print("Tag:", day)
#print("Monat:", month)
#print("Jahr:", year)


while True:
    time.sleep(3600.0)
    day=7
    month=4
    year=now.tm_year
    if month<4:
        j=year-2020
    elif month==4:
        if day<4:
            j=year-2020
        else:
            j=year-2019
    else:
        j=year-2019


    if month<4:
        m=month+7
    elif month==4:
        if day<7:
            m=month+7
        elif day>=7:
            m=0
        else:
            m=month-4
    else:
        m=month-4




    if day<7:
        t=day+24
    elif day==7:
        t=0
    else:
        t=day-7
    print(j , ":" , m , ":" , t) #vllt noch h und min???
