Learning Tour of Python ——— time module

In Python, there are usually several ways to represent time:

• Timestamp (timestamp): The timestamp represents the offset that is calculated in seconds, starting January 1, 1970 00:00:00. We run "type (Time.time ())" and return the float type.
• Formatted time string (format string)
• Structured time (Struct_time): Struct_time A total of 9 elements in total nine elements: (year, month, day, hour, minute, second, week of the year, Day of the year, summer Time)

Between them can be converted

                          Time.localtime () If you do not add seconds, the default is T Ime.time ()       tuple                                                    ,         &N Bsp             time.localtime  default can not fill in

                           time.gmtime () UTC time &N Bsp       tuples                                                      ,         &NB Sp                          ,         &NB Sp          time.strftime ("%y-%m-%d%x", Time.localtime ())     string

Timestamp    ---------------------------------------->                & nbsp: Structured time                    ------------------------------------- >  format time                 <---------------------------------------                          ,         &NB Sp                   <--------------------------------------

Time.mktime () floating point time.strptime (' 2011-05-05 1 6:37:06 ', '%y-%m-%d%x ') tuples

both structural and timestamp can be converted to ' Sun June 20 23:21:05 1993 ' In this form of string.

Parameter structure asctime ([t]) if there are no parameters, the Time.localtime () will be passed in as a parameter

When the parameter timestamp ctime ([secs]) is none, the default Time.time () is the argument.
