the arguments are similar to aspect oriented programming (so you could google that).
sometimes you want to do a similar thing in various places in your code. the classic example is logging when a method is called. rather than adding logging statements to every method, you can use a decorator - you place the logging code in one place (the decorator definition) and then add the decorator to each method you want to log. in addition to the aspect oriented approach (or at least extending it from how it is used in other languages), decorators can take advantage of the way python is structured to make fundamental changes to how methods work. so in python decorators can also do things like define static and class methods. so they provide a unified approach to what, in other languages, tend to be unrelated ideas. andrew Johny wrote: > Hi, > Can anyone explain to me what are decorators for?
