datetime type conversion

1. Convert time to datetime

1）datetime.datetime.fromtimestamp( tm )

2）datetime.datetime.utcfromtimestamp( tm )

 

二、datetime->time

1）dt01.timestamp()

2）dt01.timetuple()

 

Demo:

from time import time

from datetime import datetime

 

time01 = time()

print ( " Before conversion: " , time01)

print ( " After conversion: " , datetime.fromtimestamp(time01))

 

dt01 = datetime.today()

print ( " Before conversion: " , dt01)

print ( " Convert to timestamp: " , dt01.timestamp())

print ( " Tuple into time: " , dt01.timestamp())

 

Results of the:

C: \ python \ python.exe C: /python/demo/file3.py

Before conversion: 1519892355.5060892

After conversion: 2018-03-01 16:19:15.506089

Before conversion: 2018-03-01 16:19:15.506089

Converted to timestamp: 1519892355.506089
