Import time

Print (Time.time ()) printing timestamp from UNIX release time
Print (Time.ctime ()) printing Current time
Print (Time.ctime (Time.time () -86400)) prints the current time minus one day

Time_obj = Time.gmtime ()
Print (Time_obj.tm_year,time_obj.tm_mon) Specifies that only the printed date

Print ("{a}-{b}". Format (A=time_obj.tm_year,b=time_obj.tm_mon))
Print (Time.localtime ()) printing Current time

Convert Time to Timestamp
Print (Time.mktime (time_obj))
Tm2= time.strptime ("2016-12-13", "%y-%m-%d")
Print (Time.mktime (TM2))

Time.sleep (3) pause for three seconds
Print ("111111111")

Specify format printing
TM = Time.strftime ("%y%m%d%h:%m:%s", Time.gmtime ())
TM1 = Time.strftime ("%y%m%d%h:%m:%s", Time.localtime ())
Tm2= time.strptime ("2016-12-13", "%y-%m-%d")
Print (Time.mktime (TM2))

Import datetime

Print (Datetime.date.today ()) printing results 2016-12-13
Print (Datetime.date.fromtimestamp (Time.time ()))

Print Current time
Current_time = Datetime.datetime.now ()
Print (Current_time)
Print (Current_time.timetuple ())

Print (Datetime.datetime.now () + Datetime.timedelta (days=-1)) prints the current time minus one day or one extra day
Print (Datetime.datetime.now () + Datetime.timedelta (hours=10)) minus one hour

Specify a date to print
A= Datetime.datetime.now ()
Print (A.replace (2016,12,10))

Specify format printing
Print (Datetime.datetime.strptime ("2016-12-13 19:23", "%y-%m-%d%h:%m"))

Judging size
Current_time = Datetime.datetime.now ()
t = current_time.replace (2015,5)
Print (current_time>t)

Import logging

Simple printing

Logging.basicconfig (filename= ' Example.log ', level=logging.info, defining file and INFO levels
format= '% (asctime) s% (message) s ', datefmt= '%y-%m-%d%i:%s%p ') print Date
Logging.debug (' This message shouid go to then log file ')
Logging.info (' S should this ')
Logging.warning (' and this too ')

Complex
Import logging

Logger = Logging.getlogger (' test-log ') defines the module name or user name
Logger.setlevel (logging.info) set Local level

ch = logging. Streamhandler ()
Ch.setlevel (logging. DEBUG) set global level

FH = logging. Filehandler ("Access.log") Append file name
Fh.setlevel (logging. WARNING) level
Fh_err = logging. Filehandler ("Error.log") file
Fh_err.setlevel (logging. ERROR) level

Formatter = logging. Formatter ('% (asctime) s-% (filename) s-% (levelname) s-% (message) s ') time format
Formatter_for_file = logging. Formatter ('% (asctime) s-% (levelname) s-% (message) s ') time format

Ch.setformatter (Formatter) specify format
Fh.setformatter (formatter_for_file) Specify format
Fh_err.setformatter (Formatter) specify format

Logger.addhandler (CH) Registration
Logger.addhandler (FH) Registration
Logger.addhandler (fh_err) registration

Set Print content
Logger.debug (' Debug message ')
Logger.info (' info message ')
Logger.warn (' Warn message ')
Logger.error (' Error message ')
Logger.critical (' critical message ')
