SyntaxError: Missing parentheses in call to 'print'. Did you mean print(allLines[5])?

[hopezh]

I got the following error following the simple demo code as shown on GitHub for the GH_CPython component. May I ask why this error is related to the print function which I didn't use at all?

Traceback (most recent call last):
  File "C:\GH_CPython\PythonFileWritten_2.py", line 36, in <module>
    import Grasshopper as gh
  File "C:\GH_CPython\Grasshopper.py", line 99
    print allLines[5]
                 ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print(allLines[5])?

The code is here:
