I am trying to write a script in the Tool Validator so that the user can choose one of three options in the first parameter, and based on the user's choice, the other 3 parameters are either enabled or disabled.  However, I cannot seem to get it to work properly.  Nothing happens in the tool when I change the first parameter.  My other 3 parameters are feature sets.  The "Add Records Interactively" part is greyed out while the "Use records from" is enabled in all of them.  My script is below: class ToolValidator:   """Class for validating a tool's parameter values and controlling   the behavior of the tool's dialog."""   def __init__(self):     """Setup arcpy and the list of tool parameters."""     import arcpy     self.params = arcpy.GetParameterInfo()     print self.params   def initializeParameters(self):     self.params[1].category = "Feature Types"     self.params[2].category = "Feature Types"     self.params[3].category = "Feature Types"                 """Refine the properties of a tool's parameters.  This method is     called when the tool is opened."""     return   def updateParameters(self):     if self.params[0].altered:       if self.params[0].value == "Point":         self.params[1].enabled = 1         self.params[2].enabled = 0         self.params[3].enabled = 0       elif self.params[0].value == "Line":         self.params[1].enabled = 0         self.params[2].enabled = 1         self.params[3].enabled = 0       elif self.params[0].value == "Polygon":         self.params[1].enabled = 0         self.params[2].enabled = 0         self.params[3].enabled = 1       """Modify the values and properties of parameters before internal     validation is performed.  This method is called whenever a parmater     has been changed."""     return   def updateMessages(self):     """Modify the messages created by internal validation for each tool     parameter.  This method is called after internal validation."""     return What am I doing wrong?  I'm completely stumped!

Not quite sure how to phrase this question succinctly...  I have a really long code that is working just fine until it gets to a certain point where I am trying to format some list output.  The elements of the list will then be used to populate a table in an Access database.  I've split the list part of the code out and run it in PythonWin and it works.  However, when I run the entire code through the toolbox as a script tool I get this error: 'unicode' object is not callable on this line: finalList = [elt[0] + " (" + elt[1] + ")" if type(elt) == list and elt[0] == "ETSc" else str(elt) for elt in outlist] Is the problem running it through a script tool?  And how would I fix it?  I can't post the entire code as it is over 300 lines but am posting the relevant part below: #Get ETSc tables # obstable = "L:\\Projects\\IFWapplications\\ETSc\\ETSc.mdb\\tblObservation" LUtable = "L:\\IFW-Data\\ETSc.gdb\\tblSpatialLU" SpTab = "L:\\Projects\\IFWapplications\\ETSc\\ETSc.mdb\\tblSpecies" #Create empty lists ObsIDList = [] SpeciesList = [] ImpactList = [] outlist = [] finalList = [] #Use Cursor to determine if there is an ETSc record # try:     HabCur = arcpy.SearchCursor(ProjectSF)     for row in HabCur:         VerId = row.getValue("ERVerID")         ImpactList.append(VerId)         habval = row.getValue("HABTYPE")         if row.HABTYPE == "ETSc":             EtscList = []             outetsclist = []             EtscList.append(habval)             FID = row.getValue("FEATID")             fld = "ShapeID"             whereclause = fld + "=" + "'" + FID + "'"             LUCur = arcpy.SearchCursor(LUtable, whereclause)             for row in LUCur:                 obsnum = row.getValue("ObsID")                 ObsIDList.append(obsnum)             del LUCur, row             for obs in ObsIDList:                 scr = arcpy.SearchCursor(obstable)                 for row in scr:                     if row.getValue("ObsID") == obs:                         sp = row.getValue("Species")                         SpeciesList.append(sp)                 del scr, row             for species in SpeciesList:                 spcur = arcpy.SearchCursor(SpTab)                 for row in spcur:                     if row.getValue("SciName") == sp:                         CommonName = row.getValue("CommonName")                 del spcur, row                 EtscList.append(CommonName)                 for element in EtscList:                     if element not in outetsclist:                         outetsclist.append(element)             ImpactList.append(outetsclist)         else:             ImpactList.append(habval)     #get a list with unique values     for I in ImpactList:         if I not in outlist:             outlist.append(I)     arcpy.AddMessage(str(outlist))                #format elements in list     finalList = [elt[0] + " (" + elt[1] + ")" if type(elt) == list and elt[0] == "ETSc" else str(elt) for elt in outlist] ...

Could somebody please tell me what is going wrong with this program?  I keep getting an ERROR 999999 for the line with the cursor.  But I've checked my syntax, spelling, capitalization, etc. and I can't figure out why it won't work!!  I am trying to loop through a list of feature classes, intersect each of them with a buffer polygon, and then join the tables for the resulting intersect layer with the buffer polygon table.  Then I need to set the "PERCENTAGE" field in each one to the bufferarea/habitat area * 100.  Since it is looping through the list of feature classes, I have to use variable names for the fields.  Is this what is clogging it up? I have been struggling with this for a week!!!! Hopefully this will keep the indentation, but here is the part of the program that is choking on the update cursor: IntersectLyr = arcpy.MakeFeatureLayer_management(BufferPoly, "buffpolylyr") fcList = arcpy.ListFeatureClasses("selfts_*", "Polygon") for fc in fcList:     desc = arcpy.Describe(fc)     outFC = desc.baseName.strip("selfts_") + "_Intersect"     in_features = [IntersectLyr, fc]     #Perform Intersect between bufferpoly and selected features in each habitat feature class     arcpy.Intersect_analysis(in_features, outFC)     arcpy.AddField_management(outFC, "PERCENTAGE", "Double")     des = arcpy.Describe(outFC)     outFClyr = des.baseName + "lyr"     arcpy.MakeFeatureLayer_management(outFC, outFClyr)     arcpy.AddMessage("The Intersect Layer is: " + str(outFClyr))     arcpy.AddJoin_management(outFClyr, "FID_ProjectRadius", IntersectLyr, "OBJECTID")     fldList = arcpy.ListFields(outFClyr, "*.PERCENTAGE")     for fld in fldList:         percentfld = fld.name         arcpy.AddMessage(fld.name)     fldList2 = arcpy.ListFields(outFClyr, "*.Shape_Area")     for fld in fldList2:         if fld.name == "ProjectRadius.Shape_Area":             arcpy.AddMessage(fld.name)             buffareafld = fld.name         else:             arcpy.AddMessage(fld.name)             areafld = fld.name     cur = arcpy.UpdateCursor(Intersect)     for row in cur:         buffarea = row.getValue(buffareafld)         habarea = row.getValue(areafld)         row.percentfld = (buffarea/habarea)*100         cur.updateRow(row) del cur, row A multitude of thanks in advance to anyone who can help!!

I'm trying to write a subroutine for the first time and I'm getting very confused.  I'm trying to create a tool where users would interactively add a point to a feature class (using a feature set and appending it to the original feature class).  The tool uses the interactive feature input control.  So far I've gotten that part to work and to append the new feature to the original feature class.  Now I'm trying to add in some functionality so that if the user forgets to enter a project id for the point, an error message will be printed and then a subroutine is called so they can then enter the project id.  Here is my code: # Import arcpy module import arcpy from arcpy import env #Set workspace # env.workspace = "L:/Projects/HMAP/EnvironmentalReview.gdb" # Script arguments Feature_Set = arcpy.GetParameterAsText(0) if Feature_Set == '#' or not Feature_Set:     Feature_Set = "in_memory\\{C6359898-F410-49FF-96DD-0EB59C98516A}" # provide a default value if unspecified # Local variables: ##ProjectPoints = Feature_Set ##ProjectPoints__2_ = "ProjectPoints" #define subroutine if user forgot to enter a project identifier # def subroutine1():     cur = arcpy.UpdateCursor(Feature_Set)     for row in cur:         newVal = arcpy.GetParameterAsText(1)         idValue = row.setValue(newVal)         row.updateRow(row)     del cur, row     return #Check to make sure user entered a project identifier for point # cur = arcpy.SearchCursor(Feature_Set) for row in cur:     idValue = row.getValue("ProjectID")     if idValue == None:         arcpy.AddError("PLEASE ENTER A VALUE(S) FOR PROJECT ID")         subroutine1     else:         arcpy.Append_management(Feature_Set, "ProjectPoints", "TEST", "", "")  # Process: Append I know I'm doing something wrong as far as the subroutine is concerned.  When I run the tool, it allows me to click the mouse to add a point.  Then I hit "o.k" on the interactive input window to simulate someone forgetting to input the project id.  Then the rest of the script starts to run but I get an error stating that "the name Feature_Set is not defined".  I've tried reading all kinds of documentation on defining functions but I apparently still don't quite get it.  Can anyone help?

I have a rather unique problem.  Not sure if Python is the right way to solve it, but here goes: I have some satellite (radiotelemetry) location data that I am trying to analyze for movement patterns, etc.  I want to animate certain time periods.  However because of the way the data are downloaded, I have a date field for the date but for the time, I had to make a text field and convert the time into the following format: hh:mm am/pm I think I need a singe field to make the animation work the way I want (showing consecutive locations on a map).  I'm not overly familiar with the datetime functions in Python.  Is there a way to combine these two fields into a single datetime field?  Would it be somehow easier to do this with the field calculator?  Thanks for any suggestions.  Amy Meehan Wildlife Biologist Maine Dept.
