This is probably the most complicated language statement. It may have try, many except, finally and else blocks. As soon as all these parts have their own suits it was decided to use the idea of a scope for each of them.

The except scopes are for error handling which are usually not on the main path of a program execution. That is why they are on the right hand side. The else and finally blocks on the other hand are rather on the main line of execution so they are right under the try block. The except blocks have a dotted connection to the corresponding try block. This is done to emphasize the connection between them. If there are more except blocks, then they will be one after another on the right hand side.

There is not much more to say about the try statement. Obviously each element could have both leading and side comments and if so then the comments will be shown the very same way as for the other statements which use the scope shape graphics.
