Is it possible only to declare a variable without assigning any value in Python?

Question

Is it possible to declare a variable in Python, like so?:

var

so that it initialized to None? It seems like Python allows this, but as soon

Answer 1

You can trick an interpreter with this ugly oneliner if None: var = None It do nothing else but adding a variable var to local variable dictionary, not initializing it. Interpreter will throw the UnboundLocalError exception if you try to use this variable in a function afterwards. This would works for very ancient python versions too. Not simple, nor beautiful, but don't expect much from python.
