I thought there was a way to do this easily with parameterDependencies, but can't get that to work. But below is another way: class Tool(object):     def __init__(self):         """Define the tool (tool name is the name of the class)."""         self.label = "Tool"         self.description = ""         self.canRunInBackground = False     def getParameterInfo(self):         """Define parameter definitions"""         in_feature = arcpy.Parameter(            displayName = "Feature with States",            name = "in_feature",            datatype = "Feature Layer",            parameterType = "Required",            direction = "Input")         stateField = arcpy.Parameter(            displayName = "Field with State Names",            name = "stateField",            datatype = "Field",            parameterType = "Required",            direction = "Input")         stateField.parameterDependencies = [in_feature.name]         stateName = arcpy.Parameter(            displayName = "Select one State",            name = "stateName",            datatype = "GPString",            parameterType = "Required",            direction = "Input")         stateName.filter.type = "ValueList"         stateName.filter.list = []         return [in_feature, stateField, stateName]     def updateParameters(self, parameters):         """Modify the values and properties of parameters before internal         validation is performed.  This method is called whenever a parameter         has been changed."""         if parameters[1].value:             with arcpy.da.SearchCursor(parameters[0].valueAsText, parameters[1].valueAsText) as rows:                 parameters[2].filter.list = sorted(list(set([row[0] for row in rows])))         else:             parameters[2].filter.list = []         return ...

ArcGIS wraps parameters with spaces in them in single quotes when passing multivalue parameters. If I run the following script as a toolbox script tool and pass it "a b c" and  "abc" as the first parameter, I get the below output import arcpy SAGIS_Input = arcpy.GetParameterAsText(0) SAGIS_model_new = SAGIS_Input.split(";") SAGIS_Count = len(SAGIS_model_new) for model in SAGIS_model_new:   arcpy.AddMessage(model) Notice the single quotes around the values 'a b c'? You need to strip them off with something like: for model in SAGIS_model_new:   model = model.strip("'") ... View more

To wrap things up, there doesn't seem to be a way of doing this in arcpy (ArcGIS Idea - Add 'AlreadyInitalized' to arcpy.CheckExtension function. ). So I use a try: except: clause in a context manager to do this now: class SAExtension(object):     def __init__(self):         self.name = 'Spatial'         from arcpy.sa import Int         try:             Int(1)         except:             self.checkedout = False         else:             self.checkedout = True     def __enter__(self):         if arcpy.CheckExtension(self.name) == "Available":             arcpy.CheckOutExtension(self.name)         else:             raise ValueError("%s license isn't available" % self.name)     def __exit__(self, *args):         if not self.checkedout:             arcpy.CheckInExtension(self.name) with SAExtension:     #do some raster analysis ...

You've got your find string and replacement string in the wrong order. Try: arcpy.CalculateField_management("lyrsdePipeInsp", "Photo1", r'Replace( [Photo1],"M:", "\\vancouver.root.local")',"VB") Or: arcpy.CalculateField_management("lyrsdePipeInsp", "Photo1", r"!Photo1!.replace('M:', r'\\vancouver.root.local')", "PYTHON_9.3") ...

Use a Workspace datatype - DEWorkspace​ You can limit the Workspace types allowed with a parameter filter. Something like: def getParameterInfo(self):     param0 = arcpy.Parameter(         displayName="Input GDB",         name="in_gdb",         datatype="DEWorkspace​",         parameterType="Required",         direction="Input")     param0.filter.type = "Workspace​"     param0.filter.list = ["Local Database"]     return [param0, other params etc...] ...
