Which is the correct setting for ArcPy workspace?
(Note: arcpy.env.workspace is the correct form.) If you set an environment but are not seeing the effect on subsequent tools, check the spelling and case. The scratchGDB and scratchFolder environments are read-only environments that provide a geodatabase and folder location that are guaranteed to exist.
How to find the current workspace in ArcGIS?
The logic for generating the output name is as follows: If the scratch workspace environment is set, the autogenerated output path will be the scratch workspace. If the scratch workspace environment is not set, the current workspace environment is examined. If current workspace is set, the autogenerated output will be the current workspace.
How to use listfeatureclasses ( ) in ArcPy?
Thank you for any help or advice that can be provided. Your first example will certainly not work. arcpy.ListFeatureClasses () takes 3 optional arguments and the workspace isn’t part of them, it must be defined beforehand, see the Help page of the function for the exact syntax. Resetting the current workspace isn’t such a big deal.
How is the current workspace set in ArcCatalog?
In ArcCatalog, the Scratch Workspace and Current Workspace environments are not set by default. When using the tool dialog box, output dataset names are autogenerated using the current and scratch workspace settings. The logic for generating the output name is as follows:
What should the environment settings be in ArcGIS?
Settings such as an area of interest, the spatial reference of the output dataset, and the cell size of a new raster dataset can all be specified with geoprocessing environments. A script can be executed in several ways. It can be run as a script tool in an ArcGIS application.
How is the output name autogenerated in ArcGIS?
When using the tool dialog box, output dataset names are autogenerated using the current and scratch workspace settings. The logic for generating the output name is as follows: If the scratch workspace environment is set, the autogenerated output path will be the scratch workspace.
What happens if current workspace is not set in ArcGIS Pro?
If the current workspace is set, the autogenerated output will be the current workspace. If neither the Scratch Workspace nor the Current Workspace environment is set, the autogenerated output path will be the workspace of one of the inputs. In this case, certain restrictions apply.
What happens if the scratch workspace is not set?
If the Scratch Workspace environment is set, the autogenerated output path will be the scratch workspace. If the Scratch Workspace environment is not set, the current workspace environment is examined. If the current workspace is set, the autogenerated output will be the current workspace.
Can a python script be run from an ArcGIS application?
It can be run as a script tool in an ArcGIS application. It can also be run from another script or by itself from the Python window. When a script is run inside a tool from an ArcGIS application or from another geoprocessing script, the environment settings used by the calling application or script are passed to it.
Where do I find the environment class in Python?
Environments can be accessed as read/write properties from the environment class. Spelling and case matter when setting properties in Python. Assigning a value to arcpy.env.Workspace is not the same as setting arcpy.env.workspace. (Note: arcpy.env.workspace is the correct form.)
What happens if neither scratch or current workspace is set?
If neither the scratch or current workspace is set, the autogenerated output path will be the workspace of one of the inputs. In this case, certain restrictions apply. For example, if the workspace is a coverage workspace and the output is a new feature class, the output will be a shapefile to the directory above the coverage workspace.
How are parameters set in a Python toolbox?
Almost all tools have parameters and you set their values on the tool dialog box or within a script. When the tool is executed, the parameter values are sent to your tool’s source code. Your tool reads these values and proceeds with its work.
Where do I find the parameters in ArcGIS Pro?
To access script tool properties, right-click the tool, click Properties, and click the Parameters tab. To add a new parameter, click the first empty cell under the Label column and type the name of the parameter. This is the name that will be displayed on the tool dialog box and can contain spaces.
What does parameterdependencies do in Python toolbox?
For a derived output parameter, parameterDependencies is set to the input parameter that will be modified by the tool. For input parameters, parameterDependencies contains the name of other parameters used by the data type.
