Re: Loop through attributes in a layer and zoom to selected feature

Thanks Dan, it's really good, but what i need is a button to loop through attributes, manually edit something (like insert in attribute table a 1 for error and 0 for no error) and loop to the next? Is this possible? This is what I have so far, but how to stop the loop after each for statement and restart in python the place I left the loop? import arcpy import os import arcpy mxd = arcpy.mapping.MapDocument("CURRENT") df = arcpy.mapping.ListDataFrames(mxd, "")[0] SelLayer = arcpy.mapping.ListLayers(mxd, "Aenderung_MToS_6417341", df)[0] for row in arcpy.SearchCursor(SelLayer):     df.extent = row.SHAPE.extent #Set the dataframe extent to the extent of the feature     df.scale = df.scale * 1.07 #Optionally give the shape a bit of padding around the edges     arcpy.RefreshActiveView()     #Put in your export here ...

Re: Rename layer with unsupported signs in a mxd via python?

This: import arcpy import os mxd = arcpy.mapping.MapDocument("CURRENT") for lyr in arcpy.mapping.ListLayers(mxd):     if lyr.supports("DATASOURCE"):         arcpy.AddMessage("Layer: " + lyr.name + "  Source: " + lyr.dataSource) for lyr in arcpy.mapping.ListLayers(mxd):     lyrname = str(lyr.name)     print lyrname     lyrname_replaced = lyrname.replace(" ","_")     lyr.name = lyrname_replaced     arcpy.AddMessage(lyrname_replaced) arcpy.RefreshTOC() leads to this error: File "R:\Karto\zGIS\Python\RenameLayerinMxd.py", line 16, in <module>     lyrname = str(lyr.name) UnicodeEncodeError: 'ascii' codec can't encode character u'\xe4' in position 3: ordinal not in range(128) Any ideas? ...

Multiclip only selected features in two for loops?
