decorators question

[king kikapu]

At first, i am coming from another (language) programming world (C#
mainly) and i hope you understand my wonders.

Ok then, you tell me that the interpreter always execute the code in a
module...If there are only def declarations in the module and no code
to invoke them it does not execute anything. It must have a body (a
call to a(some) method(s)) so it can execute something, right ??

In Soni's example (Soni thanks for the code), it indeed prints "called
foo" but if i remove the @foo statement,
as i see right now in the debugger, it does not execute anything.

I recap: if i put only functions declarations on a .py file, like
these:
def A(): print "a"
def B(): print "b"
def C(): print "c"

and run the program, nothing happens, nothing executed. I have to put a
statment like print A() or b() to cause code execution.

But if i simple declare a decorator for one function, like the one that
Soni gave me, then it caused the deco function to execute. Why is that
??
