[GIS] ListRasters not recognizing raster files in python

arcgis-10.1arcpyerror-000732listraster

I have 2 rasters in my workspace, one in TIFF Format and the other in GRID format: "C:\ExampleFolder"

When I use the python script:

import arcpy
>>> rasl=arcpy.ListRasters("C:\ExampleFolder")
>>> print rasl
None

Python does not recognize my raster files. I'm attempting to use the script in this previous question:

Clip raster using shapefile into multiple rasters using ArcGIS Desktop?

I keep receiving error:
ERROR 000732: Input Rasters: Dataset does not exist or is not supported.

Any reason why Python does not recognize my raster?

Try explicitly defining the workspace:

import arcpy

arcpy.env.workspace = r'C:\path\to\your\ws'
rasl = arcpy.ListRasters()

The documentation shows that you cannot include the path of your workspace in the ListRaster function:

The workspace environment must be set first before using several of the List functions, including ListDatasets, ListFeatureClasses, ListFiles, ListRasters, ListTables, and ListWorkspaces.

arcpy.ListRasters ({wild_card}, {raster_type})

The errors you are encountering are a direct result of not inputting the correct number of parameters into the tool you are calling. Create Feature Dataset requires both out_dataset_path and out_name.

In addition to this there are some other issues with your code.

The help documentation for the Feature Class to Geodatabase tool states:

The inputs can include shapefiles, coverage feature classes, VPF feature classes, or geodatabase feature classes

You are attempting to input a feature dataset. Since you're choosing to loop through your feature classes I would think the input to this process would be a feature class.

Try this modified version of your code where a feature class in used in place of the feature dataset.

    dsList = arcpy.ListDatasets()
    print dsList
    for dsGEO in dsList:
        arcpy.CreateFeatureDataset_management(dsGEO, **out_name**)
        fcListGEO = arcpy.ListFeatureClasses(dsGEO)
        for fcGEO in fcListGEO:
            arcpy.FeatureClassToGeodatabase_conversion(fcGeo, **output_geodatabase**)

Pending the rest of your code is correct this will loop through each feature class inside of each feature dataset and add it to your geodatabase.

Your path names are invalid.

In place of:

env.workspace = "C:\Users\srchang\Desktop\outputshp"

try using:

env.workspace = r"C:\Users\srchang\Desktop\outputshp"

and do the same for outTimes.save()
