Conventions

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, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Using Windows Explorer, create a folder named c:\gdb."

A block of code is set as follows:

import arcpy
import os
import datetime
sgdb_path = "c:/gdb/web"
sgdb_name = "Web_Bestaurants.gdb"
arcpy.CreateFileGDB_management(sgdb_path, sgdb_name)
sfc_source = "c:/gdb/Bestaurants_new.gdb/Food_and_Drinks"
sfc_dest = sgdb_path + "/" + sgdb_name + "/Restaurants"
#Copy features
arcpy.CopyFeatures_management (sfc_source, sfc_dest)
sfield_rating = "RATING"
sfield_desc = "DESCRIPTION"
arcpy.DeleteField_management(sfc_dest, sfield_rating)
arcpy.DeleteField_management(sfc_dest, sfield_desc)
input ("Web Bestaurants geodatabase created successfully, press any key to continue.")

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

import arcpy
import os
import datetime
sgdb_path = "c:/gdb/web"
sgdb_name = "Web_Bestaurants.gdb"
todaydate = str(datetime.date.today().year) + str(datetime.date.today().month) + str(datetime.date.today().day)
os.rename (sgdb_path + "/" + sgdb_name , sgdb_path + "/" + "Web_Bestaurants" + todaydate + ".gdb")

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: "In the Type drop-down list, select Point Features to create the feature class with point geometry."

Note

Warnings or important notes appear in a box like this.
