 python在linux下优化得好些吗?
为什么windows的sys一直为0.00呢?

In [32]: timeit.Timer??
Type: classobj
String Form: timeit.Timer
Namespace: Interactive
File: f:\python24\lib\timeit.py
Source:
class Timer:
"""Class for timing execution speed of small code snippets.

The constructor takes a statement to be timed, an additional
statement used for setup, and a timer function. Both statements
default to 'pass'; the timer function is platform-dependent (see
module doc string).

To measure the execution time of the first statement, use the
timeit() method. The repeat() method is a convenience to call
timeit() multiple times and return a list of results.

The statements may contain newlines, as long as they don't contain
multi-line string literals.
