mxd = arcpy.mapping.MapDocument("CURRENT")
df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0]
lyr = arcpy.mapping.ListLayers(mxd, "Cities", df)[0]

# Use the SelectLayerByAttribute tool to select New York and 
#  zoom to the selection
arcpy.SelectLayerByAttribute_management(lyr, "NEW_SELECTION", 
                                        "CITY_NAME = 'New York'")
df.zoomToSelectedFeatures()

# Export the map to a .jpg

# Clear the selection and refresh the active view
arcpy.SelectLayerByAttribute_management(lyr, "CLEAR_SELECTION")
