Python - Inheritance -

i'm not understanding online documentation how make inheritance work.

i have here:

import maya.cmds cmds   class riglegs():     def __init__(self, *args):         self.riglegs()      def riglegs(self):         self.items["side"] = "left"         self.lik = cmds.duplicate(self.ljoints["hip"], n = self.getname("hip_ik"))         in self.lik:             newname = i[0].replace("_jnt", "_ik")             cmds.rename(i, newname) 

but it's complaining there no self.items - have inherit class far large post here. can me figure out how that? i've researched online , nothing makes sense.

the other class in different file altogether.

to inherit class do:

class riglegs(base_class_name): 

an example:

class base_class():     items = [1,2,3]  class pie(base_class):     def __init__(self):         print (self.items)  instance = pie() 

you can read more in python documentation

with imports:

file (apples.py)

class base():     items = [1,3,4] 

file (main_file.py)

import apples  class pie(apples.base):     def __init__(self):         self.pies()      def pies(self):         print(self.items)  instance =  pie()
