time.time() is returning a float in either case. The difference you are
seeing is purely related to how you are printing it; executing a "print"
statement as opposed to the interactive interpreter printing a value.
Python 2.5.1 (r251:54863, Feb 6 2009, 19:02:12)
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import time
>>> print time.time()
and further notice:
>>> x = time.time()
Keep in mind that while a float may have a large apparent precision,
there's no promise that the actual value returned by the OS has that much
precision. You should be fine if all you're looking for is ms, but I
wouldn't count on much more than that.
