Use print() function in both Python 2 and Python 3

[cclauss]

Legacy print statements are syntax errors in Python 3 but print() function works as expected n both Python 2 and Python 3.

Just slightly confused here. There is no python3 for Jython. The latest version of Jython is 2.7.1. It would surely be reasonable if there were to be python3 support for Jython, but I thought I had read somewhere that there wouldn't be.

Note that print() is a defined method in GhidraScript, so when you call it from a PythonScript, it's actually calling our defined Java method.

[cclauss]

Does that redirect happen even when from __future__ import print_function is used?

[ryanmkurtz]

I just tested this out and I was wrong, GhidraScript's print() method is not actually callable from our Jython environment, which was unexpected. And it looks like you don't need to import anything to use the built-in print() function...Jython 2.7.1 already knows about it somehow.

Try print("A", "B") on Jython with and without the import as discussed at jython/book#6 (comment)

[ryanmkurtz]

The import has no effect on print("A", "B") in our scripting environment. It's just prints ('A', 'B') in both cases.

Closing... With 125 days left until Python 2 end of life, it is clear that an upgrade is not possible.
