python source benchmark

[seung-won hwang]

Hello,

I'm trying to benchmark python source with clock() function, but
my code below returns negative value. I am not sure if my code is
wrong or clock() is not suitable for getting CPU time... Any comment
would help me a lot. Thanks.



My code:
  scl=time.clock()
	...
  fcl=time.clock()
  print "Execution Time: =", fcl-scl

Reference:
clock () 
Return the current CPU time as a floating point number expressed in
seconds. The precision, and in fact the very definition of the meaning of
``CPU time'', depends on that of the C function of the same name, but in
any case, this is the function to use for benchmarking Python or timing
algorithms
