newbie questions about objects properties...

[slowbullet]

Hi everyone,
Still confused between objects and properties..

When I run this:

from datetime import date
from datetime import time
from datetime import datetime

  
today = datetime.now()
f = today.time()
print f

print datetime.time(datetime.now())
 

Questions: When I'm running f = today.time() does this mean I'm calling the time method from the object "today" ? Or am I calling the time method from the datetime module and use today variable as "data input" ?

Why datetime.time(datetime.now()) is equivalent ? what is the "datetime.time()" ? a method straight from the datetime module ?

How should I code ? Do I need initialise objects by assigning a variable or can I call them straight like in the print datetime.time example ?


Also on the same lines..

import os 
print os.name;

Why above I can't do the below instead ? (this to understand properties...)

import os 
a = os.name
print a.name
