Better way to log method calls in Python?

Question

We can code out some sort of logging decorator to echo function/method calls like the following:

def log(fn):
    ...

@log
def foo():
    ...

class Foo(obj

I'm not sure what your use case is for this, but generally, I would think more about what exactly is the problem that you're trying to solve.

That said, here's an example that might do what you want but without a decorator:

#!/usr/bin/env python
import inspect


class Foo(object):

    def foo(self):
        pass

    def bar(self, a, b):
        pass

    def foobar(self, x, y, z):
        pass

    def __getattribute__(self, name):
        returned = object.__getattribute__(self, name)
        if inspect.isfunction(returned) or inspect.ismethod(returned):
            print 'called ', returned.__name__
        return returned


if __name__ == '__main__':
    a = Foo()
    a.foo()
    a.bar(1, 2)
    a.foobar(1, 2, 3)

Output:

called  foo
called  bar
called  foobar
