Thanks for all the responses!

I just downloaded 4.13 from the website. So ok, it's Python 2. Fair enough. But I get a strange error which feels like a Python 3 error:

Say, I write the following script:

import calibre
print calibre.__version__

Then I call

calibre-debug script.py

and get an error:

Python function terminated unexpectedly: invalid syntax (script.py, line 2)
Traceback (most recent call last):
  File "/Applications/Optional/calibre.app/Contents/Resources/Python/lib/python2.7/site.py", line 187, in main
    return run_entry_point()
  File "/Applications/Optional/calibre.app/Contents/Resources/Python/lib/python2.7/site.py", line 121, in run_entry_point
    return getattr(pmod, func)()
  File "site-packages/calibre/debug.py", line 348, in main
  File "site-packages/calibre/debug.py", line 260, in run_script
  File "/Users/toki/devel/calibre/play/script.py", line 3
    print calibre.__version__
                ^
SyntaxError: invalid syntax

But a Python3 script like

import calibre
print(calibre.__version__)

works fine. Why's that?
