why and when we should do it?

[Su Wei]

hi,everybody,Sorry to bother you. 
i hvae seen some code like this before:

class BusinessBO :
    dev __init__(slef):
        #write you own code here
    dev businessMethod :
        #write you own code here
pass

why and when we should add the keyword "pass" ?

and some time i have seen

class SomeObject(Object) :
      #some code

why and when we should inherit Object?

thanks in advanced.

原来在我的记忆深处，
还残留着宁静而又幸福的瞬间。
