Conventions

In this book, you will find a number of text styles 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: "After we have our map, we can use add_layer to add our stations_item to the preceding map1."

A block of code is set as follows:

    for fc in fcs: 
      fields = arcpy.ListFields(os.path.join(input_ds, fc)) 
      field_names = [field.name for field in fields] 
      for k, v in field_domains.iteritems(): 
      if k in field_names: 
        arcpy.AssignDomainToField_management(fc, k, v)

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

  npm install -g json 

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Double-click on Add ArcGIS Server."

Warnings or important notes appear like this.

Tips and tricks appear like this.
