Class into a timeit function

I have to make a class with a couple of methods in it but at the end I have to measure 5 times of duration.

I was thinking about this code but I don't know if it's possible to add class into a timeit.timeit statement.

class MyExcercise(Thread):
    def run():
        i = 0
        while i <= 10000000:
            i+=1

if __name__ == "__main__":
    import timeit

    for _ in range(5):
        a = timeit.timeit(MyExcercise(??????), number=1)
        print(f'Time a is to: {a: .3f} second(s)')

How can I make this code ready to use with class? (for now it's only error)

Later I have to multiply a thread and a number of processes but for now, how can I deal with it?

Edit:

Code works without class (but I have to do this with class).

def run():
    i = 0
    while i <= 10000000:
        i+=1

if __name__ == "__main__":
    import timeit

    for _ in range(5):
        a = timeit.timeit(run, number=1)
        print(f'Time a is to: {a: .3f} second(s)')


Time a is to:  0.238 second(s)
Time a is to:  0.247 second(s)
Time a is to:  0.260 second(s)
Time a is to:  0.248 second(s)
Time a is to:  0.250 second(s)

Edit 2:

Yes, my task is to measure my process with one thread, then with 4 threads, next in 4 processors in my computer.

Solution

  • You can pass globals() as global parameter in the timeit method.

    import timeit


class MyExercise():
    def run(__self__):
        i = 0
        while i <= 10000000:
            i += 1


if __name__ == "__main__":
    for _ in range(5):
        a = timeit.timeit("MyExercise().run()", globals=globals(), number=1)
        print(f'Time a is to: {a: .3f} second(s)')

    Output:

    Time a is to:  0.387 second(s)
Time a is to:  0.383 second(s)
Time a is to:  0.382 second(s)
Time a is to:  0.381 second(s)
Time a is to:  0.382 second(s)
