In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.
Code words in text are shown as follows: "We can include other contexts through the use of the include
directive".
A block of code is set as follows:
def nn_movie(movie_likeness, reviews, uid, mid): likes = movie_likeness[mid].argsort() # reverse the sorting so that most alike are in # beginning likes = likes[::-1] # returns the rating for the most similar movie available for ell in likes: if reviews[u,ell] > 0: return reviews[u,ell]
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
def nn_movie(movie_likeness, reviews, uid, mid):
likes = movie_likeness[mid].argsort()
# reverse the sorting so that most alike are in
# beginning
likes = likes[::-1]
# returns the rating for the most similar movie available
for ell in likes:
if reviews[u,ell] > 0:
return reviews[u,ell]
New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "clicking on the Next button moves you to the next screen".
