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: "The preceding code block scales the numerical columns: tenure
, MonthlyCharges
, and TotalCharges
."
A block of code is set as follows:
le = LabelEncoder()
for i in bin_cols:
churn_data[i] = le.fit_transform(churn_data[i])
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
project: customer_segmentation
registry: data/registry.db
provider: aws
online_store:
type: dynamodb
region: us-east-1
Any command-line input or output is written as follows:
$ docker build -t customer-segmentation .
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: "On the cluster home page, select the Properties tab and scroll down to Associated IAM roles."
