例如：时间格式是
2020-01-29 16:31:31和2025-01-23 15:30:30，怎么求得两个时间相减的时间差？
具体如下：
import time as t
import datetime as d
#定义时间差函数
def myDate(date1, date2):
date1 = t.strptime(date1, "%Y-%m-%d %H:%M:%S")
date2 = t.strptime(date2, "%Y-%m-%d %H:%M:%S")
startTime = t.strftime("%Y-%m-%d %H:%M:%S", date1)
endTime = t.strftime("%Y-%m-%d %H:%M:%S", date2)
startTime = d.datetime.strptime(startTime,"%Y-%m-%d %H:%M:%S")
endTime = d.datetime.strptime(endTime,"%Y-%m-%d %H:%M:%S")
date = endTime- startTime
return date
#参数赋值
date1 = "2020-01-29 16:31:31"
date2 = "2025-01-23 15:30:30"
#获得时间差秒数
seconds = myDate(date1, date2).seconds
#获得时间差
date = myDate(date1, date2)
print(seconds)
print(date)
