Brackets Builder has worked best for me "right out of the box". However, I run into the same problem as you (when wanting to perform console inputs) in both Brackets AND Sublime, but NOT in SciTE.

A good clean work around inside Brackets, for when you need to test programs with console inputs, is to load the extension "Open project in terminal", which will allow you to open a terminal right from your current project folder and run your python script. This allowed me to run your case from Brackets with very little hassle, and of course, it works great in a real terminal.

To make this approach even easier, I've asked the developers on GitHub, thru a raised issue, if they can add support for more terminal programs in Windows, such as ConEmu, and if they could allow intial command line arguments to be loaded, which would make this type of work that you want to do even more seamless and fast. I'll update my post once I see any improvements or alternatives to all the above points.
