I'll caution you that an edit session is only required in certain circumstances, and this is probably not one of them. Can you remove anything to do with an edit session and change your calculate field statement to: arcpy.CalculateField_management(WMeter, "WarrantyDate", 'DateAdd("yyyy",20,[InstallDate] )', "VB", "")‍‍ I assume it's getting hung up on the escaped double-quote inside the statement, but not 100% sure. ...

Please format your code for readability: /blogs/dan_patterson/2016/08/14/script-formatting  I assume your code is failing at: for fc in fcList:‍‍‍ Try printing fcList to see if it's empty. I suspect it's because your path isn't a raw string (backslashes in paths are bad). Try: arcpy.env.workspace = r"C:\EsriTraining\Python10_0\Data\SanJuan.gdb"‍‍‍ If none of this helps, please format your code and indicate where the error occurs. edit: this line is surely wrong: arcpy.Buffer()‍ ...

In Python, you would find the Point Geometry you moved, then cycle through the Polygon objects, checking if the polygon contains the point (using one of the polygon methods, like contains or not disjoint). The JS API would have similar objects/methods, but I'm not particularly familiar with it. ... View more

Your feature dataset has a set CRS, and all feature classes within it must share that same CRS. An overview of working with feature datasets—Help | ArcGIS for Desktop  I should ask: are you saving the reprojected feature class within the feature dataset? You would have to save it outside the feature dataset, which has the other CRS already set. ... View more

My guess is that you're looking to set a definition query, which creates a filtered view of your data. The features that meet the query criteria are shown on the map and table, but all the features remain in the feature class. Alternatively, you may want to change the layer symbology to only display the relevant points, keeping everything in the attribute table, but only displaying the features you want. You will not be able to delete a geographic feature and keep the table record, however. edit: reading through your link, it appears it may be possible, but my opinion is that it's a hacky way to organize your data. ...

Without specifically coding each requirement, you could look into running Minimum Bounding Geometry (RECTANGLE_BY_AREA) to create a rectangle for each feature, and select those meeting some threshold (e.g. 99% of area). The more rectangular the feature, the closer it will match the minimum rectangle. ... View more

If I understand correctly, you can load your data into a list and select those that return 'true': l = [4.035, 4.066, 3.604, 3.576,  4.593, 2.690, 2.960, 4.59] def compare(val_1, val_2, cur):     diff = abs(val_2 - val_1)     thresh = cur * 0.2     diff_minus_thresh = diff - thresh     if diff_minus_thresh > 0:         sel = True     else:         sel = False     return (l[i], diff, thresh, diff_minus_thresh, sel) print('COMPARE BACKWARD') for i in range(1, len(l)):     print(compare(l[i-1], l[i], l[i]))     print('COMPARE FORWARD') for i in range(0, len(l)-1):     print(compare(l[i], l[i+1], l[i])) COMPARE BACKWARD (4.066, 0.030999999999999694, 0.8132, -0.7822000000000003, False) (3.604, 0.46199999999999974, 0.7208000000000001, -0.25880000000000036, False) (3.576, 0.028000000000000025, 0.7152000000000001, -0.6872, False) (4.593, 1.017, 0.9186000000000001, 0.09839999999999982, True) (2.69, 1.903, 0.538, 1.365, True) (2.96, 0.27, 0.592, -0.32199999999999995, False) (4.59, 1.63, 0.918, 0.7119999999999999, True) COMPARE FORWARD (4.035, 0.030999999999999694, 0.807, -0.7760000000000004, False) (4.066, 0.46199999999999974, 0.8132, -0.3512000000000003, False) (3.604, 0.028000000000000025, 0.7208000000000001, -0.6928000000000001, False) (3.576, 1.017, 0.7152000000000001, 0.30179999999999985, True) (4.593, 1.903, 0.9186000000000001, 0.9843999999999999, True) (2.69, 0.27, 0.538, -0.268, False) (2.96, 1.63, 0.592, 1.0379999999999998, True) ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...
