The first argument to exportreport must be an arcpy.mapping object. For example: mxd = arcpy.mapping.MapDocument('current') df = arcpy.mapping.ListDataFrames(mxd, 'Layers')[0] layer = arcpy.mapping.ListLayers(df, '2013pp')[0] arcpy.mapping.ExportReport(layer,"C:\reports\2013_Graffiti.rlf","C:\reports\2013_Graffiti_report.pdf") ...

Convert your .style files to .serverstyle using MakeServerStyleSet.exe, found in C:\Program Files (x86)\ArcGIS\Desktop10.1\bin\MakeServerStyleSet.exe ... View more

Are you using server or 64 bit geoprocessing? .style files are only supported on Desktop, you may need to switch to .serverstyle files. ... View more

The list functions don't return lists if your geoprocessor is set above 9.3. To make it run in 9.3 mode, do this: gp = arcgisscripting.create(9.3) This will ensure the same behavior of this script even in 10.0/10.1. Then, use this idiom: for shape in iter(shapes.next, None): Since it returns a geoprocessing list object and not a Python list in 9.3. ... View more

Map and Layer refer to Map and Layer objects, not files. Since Walk does not go into MXD files at 10.1, these filters aren't particularly useful. ... View more

If you have a pre-authored map, you could do something hacky like this: import os import arcpy.mapping # Crack open the map mxd = arcpy.mapping.MapDocument(my_mxd) data_frame = arcpy.mapping.ListDataFrames(mxd)[0] # Iterate over the feature classes for featureclass in feature_classes:     # Make a new geoprocessing layer     arcpy.management.MakeFeatureLayer(featureclass, 'temp_layer')     # Apply symbology to it     result = arcpy.management.ApplySymbologyFromLayer('temp_layer', r'c:\path\to\my\symbology\layer')     # getOutput(0) is an arcpy.mapping Layer object     layer_object = result.getOutput(0)     # Drop onto dataframe     arcpy.mapping.AddLayer(data_frame, layer_object)     # Set correct extent     data_frame.zoomToSelectedFeatures()     # Compute an output file name     out_file_name = r"c:\thumbnails\{basename}.png".format(basename=os.path.basename(featureclass))     # Export "thumbnail" of data frame     arcpy.mapping.ExportToPNG(mxd, out_file_name, data_frame, 128, 128)     # Pull the layer out of the data frame to make room for the next one     arcpy.mapping.RemoveLayer(data_frame, layer_object)     # Delete the GP layer     arcpy.management.Delete('temp_layer') Note you don't have to apply a symbology, you can just do     # Make a new geoprocessing layer     result = arcpy.management.MakeFeatureLayer(featureclass, 'temp_layer')     # getOutput(0) is an arcpy.mapping Layer object     layer_object = result.getOutput(0) if you don't mind it being auto-symbolized like it does in GP tools. ...

You put that part with the import and def in the code block and change the expression to remove_codes(!TEXTSTRING!) ... View more

You can use regular expressions to take out the control codes in one fell swoop. import re def remove_codes(code_string):     # Get rid of enclosed text, ie {\instruction;Text to keep}     replaced_sequences = re.sub(r"{\\[^;]+;([^}]*)}", r"\1", code_string)     # Get rid of standalone \font|22pt; like sequences     new_string = re.sub(r"\\[^;]+;", "", replaced_sequences)     return new_string And this gives us >>> remove_codes(r"\pt16.25;{\fArial|b0|i0|c0|p34;15.00m}") '15.00m' in the Python window ...

Indentation error. Putting the try: statement at that indent level implicitly takes you out of the class definition and just defines an onClick function not bound to anything. Make it look like this: import arcpy import pythonaddins import traceback class ButtonClass11(object):     """Implementation for test_addin.button (Button)"""     def __init__(self):         self.enabled = True         self.checked = False     def onClick(self):         try:             # Get the current map document and the first data frame.             mxd = arcpy.mapping.MapDocument('current')             df = arcpy.mapping.ListDataFrames(mxd)[0]             # Call the zoomToSelectedFeatures() method of the data frame class             df.zoomToSelectedFeatures()         except Exception as e:             traceback.print_exc() ...

You may also want to be aware that internally Dates are stored as double precision floats, which are notoriously flaky once you get into large degrees of precision. ... View more

Could you provide a (greatly) simplified version of your code here without all those extra library calls? You're using a lot of functions and have not provided any context, so I don't know if I can make any assessment of what's going on that can be accurate. ... View more

You'd probably want to implement a tool with the onLine method defined, not a simple button. So something like this: class MyTool(object):    def __init__(self):         self.shape = 'Line'    def onLine(self, line_object):         line_length = line_object.length         # do something with line_length ...
