Tell BB about the AA instance when it is created: class BB: def __init__(self, aa): self.aa = aa def method(self): if self.aa.testflag: 2.

Seems that you're looking for a logging package (hint: there's one in
the standard lib).

A general solution would be a combination of
1/ a Singleton or Monostate (for storing application-wide settings) and
2/ a method decorator managing additionnal responsabilities according to
the values of 1.
There are examples of Singleton/Borg/Monostate/whatnot in the Python
cookbook and elsewhere - as usual, google is your friend - and a Q&D
example of decorator doing this kind of jobs in the decorator library

Re: member variables in python
I see that.But here in my case the testflags is computed inside the member function something like class AA: def __init__(self): self.test_flag = 0 # initialize def methods(self, value): save_value = _munge(value) self.test_flag = save_value Now basically I want use this self.test_flag in another class .. Basically I wanted to know if there is a better way than what i did before..not necessarly a member variable way ..just looking for a more eligant way if there is any.. -- http://mail.python.org/mailman/listinfo/python-list

What you did below isn't global. It's scope is limited to the module containing the class. If you got something that's used by multiple classes in the module, then module-scope seems like the logical choice. > eg: > > test-flag = 0 > > class AA: >def __init__(...): > > def methos(self,...): >global test-flag >test-flag = xx > > instead of something like above ..how do i put it i terms of member > variables?

Re: member variables in python
ok I reason I was going with globals is that i use this variable in another class something like this along with above testflag = 0 class AA: def __init__(...): def methos(self,...): global testflag testflag = xx class BB: def __init__(...): def method2(..): if testflag: print "do this" is there a better way to access this if we go with what you mentioned in another class ..

hi how do I write this better with member variables rather than global as you see below. eg: test-flag = 0 class AA: def __init__(...): def methos(self,...): global test-flag test-flag = xx instead of something like above ..how do i put it i terms of member variables? -- http://mail.python.org/mailman/listinfo/python-list
