time模块提供了各种功能和方式标识时间值,主要有两种标准标识时间的格式:一种是以时间戳的形式标识,该时间戳是从纪元1970年1月1日0点0分0秒至当前时间的,总共经历的秒数,以浮点小数标识,该纪元时间也依赖于个人的操作系统;另一种标识时间的形式是以一种含有9个元素的元组(标识local time)。该元组的9个元素为:...

If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace. Consequently, splitting an empty...
