How can I time a method of a class in python using Timeit

[silverburgh.meryl]

Hi,

I am using timeit to time a global function like this

t = timeit.Timer("timeTest()","from __main__ import timeTest")
result = t.timeit();


But how can i use timeit to time a function in a class?
class FetchUrlThread(threading.Thread):
def aFunction(self):
# do something ....

def run(self):
# how can I time how long does aFunction() take here?
aFunction();

Thank you.

How about this:

class Dog(object):
def run(self):
result = 10 * 20 + 3

import timeit

t = timeit.Timer("d.run()", "from __main__ import Dog; d = Dog()")
print t.timeit()

How about this:

class Dog(object):
def run(self):
result = 10 * 20 + 3

import timeit

t = timeit.Timer("d.run()", "from __main__ import Dog; d = Dog()")
print t.timeit()

Actually, you could do this:

class Dog(object):
def aFunction(self):
result = 20 + 2
def run(self):
#do stuff
aFunction()
#do other stuff
import timeit

t = timeit.Timer("d.aFunction()", "from __main__ import Dog; d =
Dog()")
print t.timeit()


It doesn't matter if you call aFunction() directly if all you want to
do is time aFunction().

class Dog(object):
def aFunction(self):
result = 20 + 2
def run(self):
#do stuff
aFunction()
#do other stuff
import timeit

t = timeit.Timer("d.aFunction()", "from __main__ import Dog; d =
Dog()")
print t.timeit()


Since you only want to time aFunction(), you can call it directly.

Thanks for all the idea.

Can 't = timeit.Timer()' run inside a thread?
And I have multiple threads running this 't = timeit.Time()' function?

__main__ is a thread isn't it? However, timeit() runs in it's own
scope, so you need to import anything you need into that scope using
the setup parameter for the Timer() constructor.

Are you seeing an error like this:

Exception in thread Thread-1:
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/2.4//lib/
python2.4/threading.py", line 442, in __bootstrap
self.run()
File "test1.py", line 34, in run
print t.timeit()
File "/Library/Frameworks/Python.framework/Versions/2.4//lib/
python2.4/timeit.py", line 161, in timeit
timing = self.inner(it, self.timer)
File "<timeit-src>", line 3, in inner
TypeError: __init__() takes exactly 2 arguments (1 given)


That was produced by this code:

----------
import time
import timeit
import threading


t = timeit.Timer("inst.f()", "from __main__ import Dog; inst=Dog()")
print t

class Dog(threading.Thread):

def __init__(self, id):
self.id = id
threading.Thread.__init__(self)

def f(self):
result = 20 + 3

def run(self):
print t
print t.timeit()


d = Dog("d")
d.start()
--------------

I can't explain that error. This works:

--------------
import time
import timeit
import threading


t = timeit.Timer("inst.f()", "from __main__ import Dog; inst=Dog()")

class Dog(threading.Thread):

def f(self):
result = 20 + 3

def run(self):
print t.timeit()

d = Dog()
d.start()
