I'm trying to use the intersect tool, with one of my inputs being from a get parameter as text. As I don't have an advanced licence I have to iterate through the list to run the intersect on each item in the list.

However, there is something about the input into the intersect analysis it doesnt like. I get the error message:

Traceback (most recent call last): File "\DRBS-NAS01\ueec\GIS\100 MT testing\BufferTest\Scripts\Intersection batch.py", line 37, in arcpy.Intersect_analysis(Des4, DirectAndIndirect + "\test2", "ALL") File "c:\program files (x86)\arcgis\desktop10.7\arcpy\arcpy\analysis.py", line 334, in Intersect raise e ExecuteError: Failed to execute. Parameters are not valid. ERROR 000732: Input Features: Dataset SOBLayer #;'\DRBS-NAS01\ueec\GIS\100 MT testing\BufferTest\Data\Designations\Ancient_Woodland_England.shp' # does not exist or is not supported Failed to execute (Intersect).

    import arcpy
    import os
    ## Working folders
    WorkingDir = os.getcwd()    ## To go up more directories: os.getcwd() 
    os.path.dirname(os.getcwd());  os.chdir(os.path.dirname(os.getcwd()))
    DesDir = WorkingDir + "\\Data\\Designations"
    OutputDir = WorkingDir + "\\Data\\Outputs"
    Interim = OutputDir + "\\Interim"
    DirectAndIndirect = OutputDir + "\\DirectAndIndirect"
    if not os.path.exists(DirectAndIndirect):
    SiteOptions = arcpy.GetParameterAsText(0)
    SiteOptionsBuffers = arcpy.GetParameterAsText(1)
    DesList1 = arcpy.GetParameterAsText(2)
    DesList2 = DesList1.split(';')
    DesBufferList = arcpy.GetParameterAsText(3)
    arcpy.MakeFeatureLayer_management(SiteOptionsBuffers, "SOBLayer")
    query = '"IndImpBuff" = {}'.format(DesBufferList)
    arcpy.SelectLayerByAttribute_management("SOBLayer","NEW_SELECTION", query)
    Des4 = ["SOBLayer"]
    for Des1 in DesList2:
        Des2 = os.path.basename(Des1)
        arcpy.Intersect_analysis(Des4, DirectAndIndirect + "\\test2", "ALL")

Could someone suggest what the problem with the Intersect input is please?

    Try creating variables for the inputs of the intersect and use print statements to see if they're what you expect. Or, since this is being run as a script tool, use AddMessage.

    You can use arcpy.Exists to check if the datasets exist.

Thanks for the comments. It's led me to a solution. The AddMessage was showing that in the DesList2 it was listing the dataset as:

u"'\DRBS-NAS01\ueec\GIS\100 MT testing\BufferTest\Data\Designations\Ancient_Woodland_England.shp'"

A bit of digging, and for reasons I dont understand, changing my loop as follows got it working:

for Des1 in DesList2:
    Des2 = os.path.basename(Des1)
    Des6 = Des1[1:-1].encode()
    arcpy.Intersect_analysis(Des4, DirectAndIndirect + "\\test2", "ALL")
