    Note the formatting in Exercise 15:

    1. Run pydoc file and scroll down until you see the read() command (method/function)...

    This is not accidental; the command you need is right there:

    python -m pydoc file
                  # ^ note argument

    read is a method on file objects. Use:

    python -m pydoc file
    

    to get the documentation for file objects. Note that this is exactly what the book told you to do, but it appears you left of the file argument.

    Alternatively, ask for just the method:

    python -m pydoc file.read
    

    The official documentation, however, is far richer and useful. See the documentation on File Objects for example.
