要将datetime转换成毫秒,我们可以利用timedelta类计算datetime对象与1970年1月1日之间的差异,然后将差异转换成毫秒。 以下是将datetime转换成毫秒的示例代码: importdatetimedefdatetime_to_milliseconds(dt):epoch=datetime.datetime.utcfromtimestamp(0)delta=dt-epoch milliseconds=delta.total_seconds()*1000returnint(mil...

datetime.timedelta 即表示一个时间的差值: 具体参考文档,这边就不多加阐述了: timedelta([days[, seconds[, microseconds[, milliseconds[, minutes[, hours[, weeks]]]) All arguments are optional and default to 0. Arguments may be ints, longs, or floats, and may be positive or negative. Only da...
