Conventions used

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

Code in text: 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: “Now let us generate the augmented data by calling the noise, scale, and rotation augmentation functions, as follows.”

A block of code is set as follows:

# Train a linear regression model on the labeled data
regressor = LinearRegression()
regressor.fit(train_data, train_labels)

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

news_headline="Label the following news headline into 1 of the following categories: Business, Tech, Politics, Sport, Entertainment\n\n Headline 1: Trump is ready to contest in nov 2024 elections\nCategory:",
response = openai.Completion.create(
engine=model_deployment_name,
prompt= news_headline,
temperature=0,

Any command-line input or output is written as follows:

pip install keras

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Change System preferences | Security and privacy | General, and then select Open anyway.”
