py视频单独时间点如何相加？
本帖最后由 一个学渣 于 2024-1-4 17:44 编辑比如视频时间点 00:09:48.336，我想加上5.1秒变成 00:14:49.336，该怎么写？
网上有一种变成日期的写法感觉很慢，还非要指定年月日，我只想获得相同格式相加的时间，求大佬解惑 from datetime import datetime, timedelta
time_str = "00:09:48.336"
time_obj = datetime.strptime(time_str, "%H:%M:%S.%f")
time_to_add = timedelta(seconds=5.1)
new_time_obj = time_obj + time_to_add
new_time_str = new_time_obj.strftime("%H:%M:%S.%f")
a = datetime.datetime.now()
b = datetime.datetime(2024, 2, 6, 12, 00)
count_down = (b - a).days timedelta 是正解! 本帖最后由 52pojie11023995 于 2024-1-9 23:24 编辑
# 自己的算法：
def TimeToSec(time):
result = time.split(":")
return int(result)*3600+int(result)*60+float(result)
print(TimeToSec("00:09:48.336"))
def SecToTime(sec1):
list = str(sec1).split(".")
sec = int(list)
hour = int(sec // 3600)
hourStr = ("0"+str(hour))[-2:]
minute = int((sec - hour*3600) // 60)
minuteStr = ("0"+str(minute))[-2:]
second = int(sec - hour*3600 - minute*60)
secondStr = ("0"+str(second))[-2:]
return hourStr+":"+minuteStr+":"+secondStr+"."+list
print(SecToTime(588.336))
print(SecToTime(588.336+12.3))
