I'll add that if you don't want to memorize the delimeters for each data type, you can always use the AddFieldDelimiters function: See the section in the Specifying a query in Python help page: http://pro.arcgis.com/en/pro-app/arcpy/get-started/specifying-a-query.htm#GUID-98106084-6ECE-4647-A50D-50EF0B46EC25 ...

It should work for getting the four extent values and adding a space between each. You can always check by printing out what is stored in the coords variable. ... View more

After you define your coords variable, try adding a print(coords) to uncover the problem. When I did this with some test data, print(coords) yielded a string: "row[0].extent.XMin&& row[0].extent.YMin&& row[0].extent.XMax&& row[0].extent.YMax" The way you are defining the coords variable it is not filling in any of the extent values. You may consider using the string format method to fill in the values for the coords variable: coords = ("{} {} {} {}".format(row[0].extent.XMin, row[0].extent.YMin, row[0].extent.XMax, row[0].extent.YMax)) For more info on the string format method, see: 6.1. string — Common string operations — Python 3.4.9 documentation  ...

Yes, the ToolValidator class is available in ArcMap. See: Customizing script tool behavior—Help | ArcGIS Desktop: http://desktop.arcgis.com/en/arcmap/10.4/analyze/creating-tools/customizing-script-tool-behavior.htm ... View more

You should be able to accomplish with with ToolValidator class. See: Customizing script tool behavior—Geoprocessing and Python | ArcGIS Desktop: http://pro.arcgis.com/en/pro-app/arcpy/geoprocessing_and_python/customizing-script-tool-behavior.htm. In particular, you can use the updateParameters method and the filter object (See: Filter—ArcPy classes | ArcGIS Desktop: http://pro.arcgis.com/en/pro-app/arcpy/classes/filter.htm). Here's a simple example from a script tool that has 2 parameters, the first is an input feature class, and the second is field name. This code derives a pick list of field names based on the input feature class. def updateParameters ( self ) :         """Modify the values and properties of parameters before internal         validation is performed. This method is called whenever a parameter         has been changed."""         # The first parameter in the tool [0] is the input feature class.         # The second parameter in the tool [1] is the derived list of field names.         string_filter = self . params [ 1 ] . filter         feature_class = self . params [ 0 ] . value         if feature_class :             string_filter . list = [ fld . name for fld in                                   arcpy . Describe ( feature_class ) . fields ]         # If the user hasn't changed the keyword value, set it to the         # default value (first value in the value list filter).         if not self . params [ 1 ] . altered :             self . params [ 1 ] . value = string_filter . list [ 0 ]         return ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ...
