Always describe the error and, if possible, send the
error text. Python error messages may seem cryptic to
a beginner but they are actually very informative once
you get used to them!

But I'll take a guess...

def readBook(book)
   import os
   if os.path.exists(filename):
   store = open(filename,'r')

The lines under the if statement should be indented.
It may just be email messing things up but since the
rest were OK I'm guessing that this is the error.
Like this:

def readBook(book):
    import os
    if os.path.exists(filename):
       store = open(filename,'r')
       for line in store:
          name = line.rstrip()
          entry = store.next().rstrip()
          book[name] = entry
       store.close()


Remember that indentation(spacing) is all important
in Python, its how python knows how much or how
little to do as a result of the if test or inside the for loop.
