The title is '... Hard Way'.  This is literally true. The author 'warns' 
beginners to not learn Python 3, which is easier to learn than Python 2, 
and works better in many ways.

Even worse, he warns people not to use Idle (or any other IDE) and use a 
plain text editor like Notepad++ and a terminal to edit and run 
programs.  This is definitely the Hard Way compared to edit and run with 
Idle.  I know from experience, because I started the way he recommends 
(editor and command prompt) and put off learning to use Idle.  What I 
fool I was.

Python will read any file as input: bytes are bytes.  Open non-text 
files in binary mode.  For example,

pic = open('image.jpg', 'rb')  # I believe this is the same in 2.x.

However, this is not useful unless you know the file layout and enjoy 
parsing it at the byte level.  Better to use a package that does that 
for you. For doing anything with images, you might use pillow, a 
friendly updated fork of PIL (Python Imaging Library), which works on 
2.6-7 and 3.2-4. I just did
C:\Programs\Python34>pip install pillow
(I have been meaning to do this anyway) and a few seconds later it is 
installed and 'import PIL' works.

For the docs, I had to go back to
https://pypi.python.org/pypi/Pillow/2.5.2
to find the reference to
http://pillow.readthedocs.org/en/latest/

In Idle I added 'pillow' to the help menu, linked to the url above, 
using the options dialog General tab, Additional Help Sources box.
