如何近似时间戳
How to approximate timestamp
我有一个以毫秒为单位的时间戳列表，例如 10:35:08.23562515422。现在以毫秒为单位，我只想在列表中包含前 3 个值，例如 10:35:08:235。有办法吗？
>>> from datetime import datetime
>>> timestamps = ['10:35:08.23562515422', '10:35:08.24862517422', '10:35:08.31060347422', '10:35:15.00860347422']
>>> for time in timestamps:
... dt = datetime.strptime(time[:-8], '%H:%M:%S.%f')
... print datetime.strftime(dt, '%H:%M:%S.%f')[:-3]
10:35:08.235
10:35:08.248
10:35:08.310
10:35:15.008
假设小时、分钟和秒总是两位数（它们应该是），它很简单：
timestamp = timestamp[:12]
