Pros
Pro Sometimes simple is best
For short scripts, a heavyweight IDE just gets in the way. It's also easier for beginners to understand.
Pro Written in pure Python/tkinter
You can dig in and change how it works.
Pro Included in standard Python distributions
You probably already have it.
Pro Debugger
It has one.
Pro Simple set up
Once dependencies like maven are installed it is up and running in minutes with one simple command.
Pro Easy horizontal scaling
Ninja is stateless by design. This makes horizontal scaling very easy and just a matter of adding servers.
Cons
Con No Tabbing for Files or Shell instances
Idle's Interactive Python Shell and the Python Text Editor are separate window applications. Many would expect them to be unified together within a single window. To create a python program file, or module, the user first opens Idle (It's Interactive Shell), then the user goes to [File] and [New File] to open the Idle Text Editor. Plus, every time a new python file is opened, a new instance of Idle runs separately. So, there are no tabbed modules. That's clumsy approach that adds the complexity of juggling around many Idle instances.
Con Little user choice in organization
Since most of the code and folder structure are automatically generated, this leaves little room to the developer on how they will organize their project.
