Fixed print statement for python3 compatibility

In my use case I had a virtual environment configured with python3 and some libraries and in Sublime I configured the project to work with the libraries and the executable from the virtual environment like this:

    "settings":
	{
		"python_interpreter_path": "/path/to/project/venv/bin/python",
		"python_package_paths": [
                    "/path/to/project/venv/lib/python3.3/",
                    "/path/to/project/venv/lib/python3.3/site-packages"
                ]
	}

When doing this the autocomplete function gives an error about the specific print statement I fixed here. When using parenthesis everything works fine!
