In computing details matter, and in communication odd personal habits 
distract from the actual message. Please reconsider your use of an "l" as a 
replacement for "I".

At least as important are the specifics of the "error". Did Python print a a 
"traceback"? This gives detailed information about the error and where in 
the code it occurs. You should always provide it (cut and paste, don't 
paraphrase).

There are bigger differences between Python 2 and Python 3 than between 
Python 3.1 and Python 3.5. An example written for Python 3.1 is more likely 
to run with Python 3.5 than 2.7. Therefore I recommend that you work through 
the book using the 3.5 interpreter.
