Better way to log method calls in Python?
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
This might be overkill, but there is a trace function facility that will inform you of a great deal of activity within your program:
import sys
def trace(frame, event, arg):
if event == "call":
filename = frame.f_code.co_filename
if filename == "path/to/myfile.py":
lineno = frame.f_lineno
# Here I'm printing the file and line number,
# but you can examine the frame, locals, etc too.
print "%s @ %s" % (filename, lineno)
return trace
sys.settrace(trace)
call_my_function()
sys.settrace(None)
