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: To check each of the versions and the latest one of them we use aws s3api list-object-versions --bucket version-demo-mlpractice to which S3 provides the list-object-versions API, as shown here."

A block of code is set as follows:

 "Versions": [
{
"ETag":
"\"b6690f56ca22c410a2782512d24cdc97\"",
"Size": 10,
"StorageClass": "STANDARD",
"Key": "version-doc.txt",
"VersionId":
"70wbLG6BMBEQhCXmwsriDgQoXafFmgGi",
"IsLatest": true,
"LastModified": "2020-11-07T15:57:05+00:00",
"Owner": {
"DisplayName": "baba",
"ID": "XXXXXXXXXXXX"
}
} ]

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

[default]
exten => s,1,Dial(Zap/1|30)
exten => s,2,Voicemail(u100)
exten => s,102,Voicemail(b100)
exten => i,1,Voicemail(s0)

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

$  aws s3 ls s3://version-demo-mlpractice/
$  echo "Version-2">version-doc.txt

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. Here is an example: "Select System info from the Administration panel."
