I usually point out my decorator module
(http://www.phyast.pitt.edu/~micheles/python/decorator.zip) to simplify
decorator usage. In this case you would use it as follows:
from decorator import decorator
@decorator # convert logFunctionCalls into a decorator
def logFunctionCalls(function, *args, *
Fantastic, thanks Leif and Paul, My problem is that i thought the
decorator worked at the function runtime, not when the function gets
created.

Your code doesn't work because decorators are run at function creation
time, not at function run time. Try this instead:
from itertools import count
def logFunctionCalls(function):
Compare this to your original:
def logFunctionCalls(function):
ec = FunctionCounter()
def decoratedFunction(*args,**kwargs):
print "Entering function:", function.__name__, ec.next()
function(*args,**kwargs)
return decoratedFunction
@logFunctionCalls
def doWork():
p
Hi Can someone please help me understand this (i shouldn't have tried
to learn decorators and generators at the same time..).
Im trying to create a decorator that counts the number of times a
function is run. Somthing like:
def FunctionCounter():
n=0
while 1:
yield n
n=n+
