python - 如何将微秒转换为hh:mm:ss以导航到youtube视频中的特定时间？

Question

我有一个时间步(例如2717715 microseconds)，我想将其转换为hh:mm:ss格式以从youtube视频中提取帧。我使用以下代码来做到这一点:

def convert(timestamp):
    # pdb.set_trace()
    timestamp = float(timestamp)
    # seconds = (micros/1000)%60
    # minutes = (micros/(1000*60))%60
    # hours = (micros/(1000*60*60))%24
    # pdb.set_trace
    milliseconds   = (timestamp / 1000) % 1000
    seconds    = (( (timestamp / 1000) - milliseconds)/1000)%60 
    minutes    = (((( (timestamp / 1000) - milliseconds)/1000) - seconds)/60) %60 
    hours      = ((((((timestamp / 1000) - milliseconds)/1000) - seconds)/60) - minutes)/60

    return  hours, minutes, seconds

但这是行不通的。您能告诉我代码有什么问题吗？

Answer 1

考虑到您的时间戳记是float类型，您可以使用内置的divmod函数，如下所示:

timestamp = 3 * 3600 + 7 * 60 + 20 # just creating (3h 7m 20s) float format timestamp
print(timestamp)  # gives 11240

假设您具有该时间戳记，则可以从中提取小时，分钟和秒，如下所示:

timestamp = float(timestamp)/1000000 # The timestamp is in microseconds
hours,remainder = divmod(timestamp, 3600)
minutes,seconds = divmod(remainder, 60)
print(hours)  # gives 3
print(minutes) # gives 7
print(seconds) # gives 20

希望能有所帮助。编码愉快。
