Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "scikit-learn provides the SVC class, which is a very efficient implementation that can be used in most cases."

A block of code is set as follows:

from sklearn.svm import SVC
from sklearn.model_selection import cross_val_score

svc = SVC(kernel='linear')
print(cross_val_score(svc, X, Y, scoring='accuracy', cv=10).mean())
0.93191356542617032

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this:
