python datetime example

Example of the usage of the time and datetime modules in Python, pythondatetime Time module method:Time. time (): Get the timestamp of the current time Time. localtime (): receives a timestamp and converts it to a tuples of the current time. If no parameter is specified, time. time () is input as the parameter by default. Time. localtime ()

format of the Time.asctime (), and by default the Time.time () is passed as a parameter. Time.gmtime (): Converts a timestamp to utc+0 time zone (China should be + 8 time zone, 8 hours apart), and will default to Time.time () as a parameter. Time.strftime (Format,time.localtime ()): Converts a time tuple to a formatted time character, without giving the time tuple argument the default to pass Time.localtime () as a parameter For example, th
