This prints the id() of the local (to the function w()) HMMM variable

while this prints the id() of the global HMMM variable. Python assumes that
a variable is local to a function if there is an assignment to that
variable anywhere inside that function.
If you want to change the variable (Python-lingo "rebind the name") HMMM
declare it as global in the function:
def w(fn):
global HMMM
# ...
HMMM = fn
# ...
Otherwise I've no idea what you are trying to do here...
