5.1.5 Time Object

The object created by class time represents the local times and is not related to any special date. Time can be adjusted through time zone tzinfo .

Class Datetime.time (hour=0, minute=0, Second=0, Microsecond=0, Tzinfo=none)

All parameters are optional. In addition to the Tzinfo object, other parameters are integer representations. The range of parameters is as follows:

L 0 <= Hour < 24

L 0 <= Minute < 60

L 0 <= Second < 60

L 0 <= Microsecond < 1000000

An exception ValueError is thrown when the parameter range exceeds these ranges .

Used primarily to create a time object.

Example:

#python 3.4.3

Import datetime

Time = datetime.time (hour = 10)

Print (' Time: ', time)

The resulting output is as follows:

time:10:00:00

Class Properties:

Time.min

Returns the Time object that represents the minimum.

Time.max

Returns the Time object that represents the largest.

Time.resolution

Returns the precision of the minimum difference between two time differences. is currently a microsecond.

Example:

#python 3.4.3

Import datetime

Time = datetime.time (hour = 10)

Print (' Time.min ', time.min)

Print (' Time.max ', Time.max)

Print (' time.resolution ', time.resolution)

The resulting output is as follows:

Time.min 00:00:00

Time.max 23:59:59.999999

Time.resolution 0:00:00.000001

Instance properties can only be read and cannot be modified:

Time.hour

The range is the hour.

Time.minute

The range is minutes.

Time.second

The range is in seconds.

Time.microsecond

The range is 1000000 microseconds.

Time.tzinfo

Save the time zone information object or save it as nonewhen it is not.

Example:

#python 3.4.3

Import datetime

Time = datetime.time (hour = ten, minute = 1, second = $, microsecond = 30)

Print (' Time.hour: ', Time.hour)

Print (' Time.minute: ', Time.minute)

Print (' Time.second: ', Time.second)

Print (' Time.microsecond: ', Time.microsecond)

The resulting output is as follows:

Time.hour:10

Time.minute:1

Time.second:20

Time.microsecond:30

Time.replace ([hour[, minute[, second[, microsecond[, Tzinfo]] []]

By modifying some parameters to get a new time object, other parameters that are not modified are consistent with the instance.

Example:

#python 3.4.3

Import datetime

Time = datetime.time (hour = ten, minute = 1, second = $, microsecond = 30)

New = Time.replace (20)

Print (' Time.hour: ', Time.hour)

Print (' New.hour: ', New.hour)

The resulting output is as follows:

Time.hour:10

New.hour:20

Time.isoformat ()

Returns a time string formatted with the ISO8601 standard. If the microsecond is not 0, format is formatted as HH:MM:SS.mmmmmm , and if Microsecond is 0, press hh:mm: SS to format. If there is a time zone, add the time zone later:hh:mm:ss.mmmmmm+hh:mm or hh:mm:ss+hh:mm.

Example:

#python 3.4.3

Import datetime

Time = datetime.time (hour = ten, minute = 1, second = $, microsecond = 30)

Print (' Time.isoformat: ', Time.isoformat ())

The resulting output is as follows:

time.isoformat:10:01:20.000030

TIME.__STR__ ()

The str () function of the time object is formatted, andstr (t) is equivalent to t.isoformat ().

Example:

#python 3.4.3

Import datetime

Time = datetime.time (hour = ten, minute = 1, second = $, microsecond = 30)

Print (' Time.isoformat: ', str (time))

The resulting output is as follows:

time.isoformat:10:01:20.000030

Time.strftime (format)

Formatting time is controlled by a format string.

Example:

#python 3.4.3

Import datetime

Time = datetime.time (hour = ten, minute = 1, second = $, microsecond = 30)

Print (' Time.isoformat: ', Time.strftime ('%h:%m:%s '))

The resulting output is as follows:

Time.isoformat:10:01:20

TIME.__FORMAT__ (format)

The same function as time.strftime () , just this function is used in Str.format () call.

Time.utcoffset ()

Returns the relative time of UTC. Returns None if the time zone tzinfo is empty . If not NULL, returns self.tzinfo.utcoffset (None).

TIME.DST ()

If tzinfo returns None. returns SELF.TZINFO.DST (None)if tzinfo is not empty .

Time.tzname ()

Returns the name of the time zone. If tzinfo is empty, returns None.

Example:

#python 3.4.3

Import datetime

Class GMT8 (Datetime.tzinfo):

def utcoffset (self, DT):

Return Datetime.timedelta (hours=8)

def DST (self, DT):

Return Datetime.timedelta (0)

def tzname (SELF,DT):

Return "Asia/beijing"

T = datetime.time (+, TZINFO=GMT8 ())

Print (t)

Print (T.DST ())

Print (T.tzname ())

Print (' The {} is {:%h:%m}. '. Format ("Time", T))

The resulting output is as follows:

12:10:30+08:00

0:00:00

Asia/beijing

The time is 12:10.
