Attribute annotation results in "invalid syntax" error in Python2.7?

Question

The following code

class base:
    var: int

doesn't seem to work with python2.7 and gives this error:

    var: int
       ^
SyntaxError: invalid syntax

It seems I need python3.6 or later to use attribute annotations. I am wondering how I can achieve similar functionality for python2.7?

Answer 1

I think what you are actually trying to do is typing hint in python, which is only available after python3.5 (https://docs.python.org/3/library/typing.html), so it's not possible in python2.7.

You probably should just use comments for this.
