I suspect you were actually running Python 3.x in which case "print xxx" doesn't work because print has been mad into a function (requiring parentheses). When I start each on my Mac, this is the display I get:
Python 2.7: ssmain:~ jbarnhart$ python Python 2.7.10 (default, Feb 22 2019, 21:17:52) [GCC 4.2.1 Compatible Apple LLVM 10.0.1 (clang-1001.0.37.14)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> Python 3.7: ssmain:~ jbarnhart$ ssmain:~ jbarnhart$ python3 Python 3.7.2 (default, Feb 12 2019, 08:15:36) [Clang 10.0.0 (clang-1000.11.45.5)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> You should be able to tell the version by the startup message. If you are actually running Python 2 and the code fails, copy and paste the actual error message you get and we'll puzzle it out.
