This article briefly summarizes the Python processing time and date aspects of the module, mainly the use of datetime, three modules, I hope this article is useful for learning Python friends. The first is the call of the module, many Ides have installed a lot of Python frequently used modules, so we do not need to in

Python projects often need to convert time between datetime format and timestamp format, or you need to convert UTC time to local time, this article summarizes the transformation between these time functions, for your reference.
