Everything is an object, including functions, lambdas, and generators:
g = (i for i in [])
def f(): pass
type(g).__mro__ # (generator, object)
type(f).__mro__ # (function, object)
type(lambda:0).__mro__ # (function, object)
Generators have no __dict__
but functions do!
def count(f):
def w():
w.calls += 1
return f()
# let's store an attribute in the function!
w.calls = 0
return w
@count
def f():
return 'hello'
f()
f()
f.calls
# 2
