![]() ![]() ![]() But there’s no reason why we can’t supply our own dict instead! So if we have something like this: class objectview(object): not built-in) objects in Python by default have a magic _dict_ attribute that holds all per-instance attributes of the object. However, there’s a better way, taking advantage of Python’s dynamic features. for saving in JSON format), you need to write the boilerplate export code as well. Writing the code to parse the dictionary and populate a Python object is not hard to do, but it’s boring boilerplate code that you have to write for each variant of the data structure, update when your data structure changes, and if you want to get the data back into dictionary (eg. Print "Person %s appears in %d episodes %" % (person.name, ![]() Something like this would be much nicer: for person in starfleet: This works, but bracketing and quoting those field names is tedious and looks ugly. Print "Person %s appears in %d episodes" % (person, 'characters': Īnd you have a following piece of code: for person in starfleet: For example, let’s say you have the following data structures: starfleet = [ Sometimes, though, it can be awkward using the dictionary syntax for setting and getting the items. Python’s dictionaries are great for creating ad-hoc structures of arbitrary number of items. ![]()
