Acceessing attribute from diffrent classes &diffrent modules

GTAPy

Hello Python Dev.
i am new to python ...i would like to know more about how to access attribute values within different classes, different modules ....Assum we have the following

[HTML]Module 1
Class A (self):
def AX (self):
x = 'somestring'
return x

Module 2
Class B( self, ....):
def AY (self, .....):
[here i want to use x value
from AX method in module 1][/HTML]

the question is, how to inherit the x value from module 1 and use it in module 2 in AY method, assuming that __init__ is already defined for each class and being used by other methods too.....

any help is appreciated ....

Thanks !

the question is, how to inherit the x value from module 1 and use it in module 2 in AY method

I think this is what you're asking...
module1.py

Expand|Select|Wrap|Line Numbers

 
class A (self): 

    def AX (self):

        x = 'somestring'

        return x

module2.py

Expand|Select|Wrap|Line Numbers

 
import module1
 
class B( self, ....):

    def AY (self, .....):

        inst_ClassA = module1.A()

        # inst_ClassA is now an instance of the class A from module1

        retval = inst_ClassA.AX()

        # The previous command invokes the class's method AX() 

        print retval

But like you said, this is assuming the __init__ functions are defined properly

Thanks for the Reply,

but what it should be define in __Init__ , i mean what's the proper __init__ definition to do this ?

Thanks

Well honestly for something so simple you don't need init functions. Modifying the previous code like this will perform the illustrated task:
Module1:

Expand|Select|Wrap|Line Numbers

 
class A:

    def AX (self):

        x = 'somestring'

        return x

Module2:

Expand|Select|Wrap|Line Numbers

 
import module1
 
class B:

    def AY (self):

        inst_ClassA = module1.A()

        # inst_ClassA is now an instance of the class A from module1

        retval = inst_ClassA.AX()

        # The previous command invokes the class's method AX() 

        print retval
 
def main():

    inst_ClassB = B()
 
    inst_ClassB.AY()
 
if __name__ == '__main__':

    main()

Output:

Expand|Select|Wrap|Line Numbers

 
C:\Documents and Settings\Administrator\Desktop\pythtests>python module2.py

somestring
 
C:\Documents and Settings\Administrator\Desktop\pythtests>

If you are looking to do something more advanced with classes then refer to the following tolearn about the __init__ function etc.

Do you mean this?

Expand|Select|Wrap|Line Numbers

 class A:

    def foo(self):

        print "foo"
 
class B:

    def bar(self):

        print "bar"
 
b=B()

A.foo(b)

here's my problem :

i have 2 classes , with these instantiations

[PHP]Class A:
def __init__(self):
self.service = None
self.currentVerMap = None
self.map= None
self.Name1 = None
self.Name2 = None
.
.
.
etc

def AX (self, name):
self.somevalue = gold
return self.somevalue

Class B (wx.Frame) :
def __init__(self, parent, id=wx.ID_ANY, title='', pos=wx.DefaultPosition,
size=(700,650), style=wx.DEFAULT_FRAME_STYLE):

wx.Frame.__init__(self, parent, id, title, pos, size, style)

def __BY (self, somevalue):
all i need inside this method is getting
GOLD value from Class A, method AX and use it
inside BY method
[/PHP]

plz guys .......i appreciate any help to solve this !

Thanks,

In order to use a member of the A class, you must pass an instance to the BY function.
ie:
__BY(inst_class_a)

... However, from what you are saying it doesn't seem that you fully understand the purpose of a class... Classes shouldn't ever depend on one another unless you're talking about inheritance or implementation.

You need to further explain your problem because in its current state, it doesn't make any sense.
