6.python Time Module

The time module is represented in three ways:

1. Timestamp (the timestamp is how many seconds have elapsed since January 1, 1970). ）
   

2. Structured Time.

3. String Time.

One. Show Time stamp

Time.time (): Displays the timestamp of the current Time.

Print Time.time ()

>>>1490326825.62

TWO. Displays the current structured time.

Time.localtime (): Displays the structured time of the current time, and the time stamp can also be converted to a structured time type.

t = time.localtime ()

Let's take a look at what type of data time.localtime () Returns.

Print Type (t)

>>><type ' Time.struct_time ' >

This is a structured time object, then print it and see what's in it.

>>>time.struct_time (tm_year=2017, tm_mon=3, tm_mday=24, tm_hour=11, tm_min=45, tm_sec=20, tm_wday=4, tm_yday =83, tm_isdst=0)

Tm_year: the current year.

Tm_mon: the current Month.

Tm_mday: The current date is the Number.

Tm_hour: what time Is it now?

Tm_min: the current Minute.

Tm_sec: the current number of SECONDS.

Tm_wday: is currently the day of the week (Monday represents the No. 0 day of the week, starting from 0. ）

Tm_yday: is currently the day of the Year.

Time.localtime () can pass in a timestamp format parameter and convert the timestamp to a structured time type.

Three. convert the timestamp to a formatted Time.

Time.localtime (1490326825.62)

Four. Convert the structured time to a timestamp.

Time.mktime () passes in a structured time object, transforming the structured time into a timestamp.

Five. Convert the string time to a formatted time Object.

Time.striptime (' time String ', format)

Print Time.strptime (' 2017-03-24 15:34:26 ', '%y-%m-%d%h:%m:%s ')

>>>time.struct_time (tm_year=2017, tm_mon=3, tm_mday=24, tm_hour=15, tm_min=34, tm_sec=26, tm_wday=4, tm_yday =83, Tm_isdst=-1)

SIX. converts a formatted time object into a string time format.

Time.strftime (' Format ', format time Object)

Print Time.strftime ('%y-%m-%d%h:%m:%s ', time.localtime ())

>>>2017-03-24 15:34:26

Seven. Display the string time directly.

Time.asctime () A string time is output when the default is not to add Parameters.

Asctime can pass a formatted time object and convert the formatted time object to a string format Output.

Eight. timestamp to String.

Time.ctime () will output a string time in the same way as asctime without the parameter being added by Default.

CTime can also pass in a timestamp to convert the timestamp to a string time.

Other:

Time.sleep () postpones a thread to run for a specified time in SECONDS.
