I'm too tired to try and explain, hopefully some else will. But I think
that is what you were trying to do.
Don't worry decorators are easy as once it clicks.
If it doesn't execute on function call, I don't get what the use is? I
thought if I did this, it would print out "I am decorator" ( but it
only does it on function declaration )
def dec(f):
print "I am decorator!", f
return f
@dec
def fn(x): return x
( And if it doesn't, then the logThisMethodCall() will not be logging
every time it is called, just once on declaration ?: )
