SimpleProfiler

A simpler profiler for Python functions.

Description

It works as a function decorator and writes out simple stats on standard output when the program terminates.

Usage

Import profile from SimpleProfiler and use it to decorate the functions that you want to profile/time.

Example

test.py:

from SimpleProfiler import profile

ITERATIONS = 100000

@profile
def doSomething():
	for _ in range(ITERATIONS):
		pass

@profile
def doMath(x):
	sum = 0
	for i in range(ITERATIONS):
		sum += x * x * i
	return sum

def notProfiled(x, y):
	sum = 0
	for _ in range(ITERATIONS):
		sum += x * y
	return sum

	
if __name__ == "__main__":
	for _ in range(10):
		doSomething()
		notProfiled(123, 456)
		notProfiled(321, 0)
		doMath(3)
		doMath(7**7)
		doSomething()
		doMath(666)

Output:

          name      calls         total_time       average_time
          ----      -----         ----------       ------------
   doSomething         20             0.2290             0.0115
        doMath         30             2.7212             0.0907

PS: Change range to xrange in the test with Python < 3.0.
