Hello, Jeff Hardy ).
1)
It is a good reference. But the methods must be defined in advance (class
A). If I write ttt ('i') without defining it in the class A, I get an
error. Use __getattr__ in class A does not work.
class A(object):
def salutation(self, accusative):
# code
def farewell(self, greeting, accusative):
# code
......................
salutation("world")
farewell("goodbye", "world")
ttt('yy')
name 'ttt' is not defined.
2)
A good option would be:
import sys
class Foo(object):
def __getattr__(self, t):
print 'use __getattr__ - ', t
return type(t, (object,), {})
def funct1(self): pass
def funct2(self): pass
sys.modules[__name__] = Foo()
ttt('yy')
name 'ttt' is not defined.
__getattr__ not work (((.
