Question

I have a specific question regarding the usage of profiler. I am new to python programming
I am trying to profile a function which I want to invoke as a class method, something like this

import profile

class Class:
    def doSomething():
        do here ..

    def callMethod():
        self.doSomething()

instead of this I want to use

    profile.run(self.doSomething())

but the profile.run expects the string inside it and I get error

TypeError: exec: arg 1 must be a string, file, or code object

Can somebody please help?

Thank you

Fixed!!!

Instead of profile, I used cProfile module that as per the python docs has much lesser overhead

Ref : http://docs.python.org/library/profile.html#introduction-to-the-profilers

with cProfiler, one can actually pass the local and global params using the runctx module
so for the same problem, I did the following:

import cProfile
cProfile.runctx('self.doSomething()',globals(),locals())

and it worked 🙂

also, if you have more params to pass you can like

import cProfile
cProfile.runctx('self.doSomething(x,y,z)',globals(),locals())

Thanks for all help
