I am trying to write a decorator that times an instance method and
writes the results to a class member variable. For example:
def timeMethod(func):
def wrapper(self, *args, **keyArgs):
t1 = time.time()
res = func(self, *args, **keyArgs)
duration = time.time() - t1

I have a class (A, for instance) that possesses a boolean (A.b, for
instance) that is liable to change over an instance's lifetime.
Many of the methods of this class (A.foo, for instance) should not
execute as long as this boolean is false, but should instead raise an
exception.

Hello,
I have a decorator problem and hope someone is able to help me out/
assist me. Thanks in advance.
Suppose:
### Begin some_library_module ###
def some_decorator(some_method):
def inner(an_arg, *args, **kwargs):
return some_method(an_arg, *args, **kwargs)
return inner

Short answer: this makes no sense.
Absolutely right, took me a while to figure that out though :-)
Lesson learned (again): If it really seems impossible to do something in
Python, it is likely the proposed solution is flawed.

If you are using Python 2.5, you can use functools.update_wrapper to
simplify your life. For instance
from functools import update_wrapper # requires Python 2.5
def trace(func):
def wrapper(*args,**kw):
print 'calling %s with args %s' % (func.__name__,args)
return func(*args,*

I just discovered decorators. Very cool. My question is that I can't
figure out how to make a decorator not be restricted to a function so it
would also work on a method.
Here's my code:
def g(expr):
def rpt(func):
def wrapper(t):
for ii in range(expr):

Check the Python Wiki. For the decorators in particular I wrote a
module that
you may find useful. See

thx to all
now I understand how it works and why it should be done in this way
so it's possible to write more than only one declarator

Yes, I think this does what you want:

def actual_timelogger(function):
def wrapper(*a,**kw):
logfile.write("
