That's why I suggest calculate the Z-coordinates at the 2D intersection point. If it's the same for both line, then they intersect 3D. ... View more

Ah, so it was. I thought you meant comma-delimited string. You can't make a list any other way  ... View more

I suppose you could test if the lines intersect in 2D. If so, find the XY coordinates where they intersect. Calculate the Z coordinate at those locations. See if they're the same. If the lines don't intersect in 2D, they don't intersect in 3D. ... View more

Question 1: change one of the z coordinates so that the lines clearly do not intersect along the z-axis, but still would intersect along the xy plane, to check. Question 2: you go through a lot of work to create a feature class called 'homeadd', and then insert into a different feature class, 'polyline1add'. Is that intentional?  ... View more

The output of MakeFeatureLayer is a feature layer, not a file, so don't include the path. Then, the input to SelectLayerByAttribute is a feature layer, so again, no file path. arcpy.MakeFeatureLayer_management(os.path.join(ruta,"Vias_Join_p"), "Vias_Join_p_lyr") arcpy.SelectLayerByAttribute_management("Vias_Join_p_lyr" , "NEW_SELECTION","descripcio = descripcio_1 AND nam = nam_1 AND  na2 = na2_1 AND acc = acc_1 AND rst = rst_1 AND typ = typ_1 AND hct = hct_1 AND wtc = wtc_1 AND loc = loc_1 AND ltn = ltn_1 AND mes = mes_1 AND tuc = tuc_1 AND txt = txt_1 AND subtipo = subtipo_1")‍‍‍‍ ...

I'll try to steer you toward creating a new field and populating it by an ID that you can use to either merge together or leave alone, then use Dissolve to make your new feature class. Selections are very slow through Arcpy. An alternative would be to loop through your features using an UpdateCursor and use the Polyline union method to make your new geometries (one feature at a time), but this would be quite a bit more complicated. ...

I'd probably go a step farther and put everything into a dictionary. Assumes all your numbers are 5 digits: vals = ['CC12345', 'CAL12345', 'CC12346', 'CAL12341', 'CC12349', 'CC12348'] vals_dict = {} for val in vals: vals_dict[val[:-5]] = max(val[-5:], vals_dict.get(val[:-5], 0)) print(vals_dict) {'CC': '12349', 'CAL': '12345'}‍‍‍‍‍‍‍ ...

Extract the numerical part of the code first, otherwise '+' means concatenate, and you can't concatenate string and int. vals = ['CC12345', 'CC12346', 'CC12349', 'CC12348'] print(max(vals)) max_int = int(max(vals)[2:]) print(max_int) max_int += 1 print(max_int) new_code = 'CC' + str(max_int) print(new_code) CC12349 12349 12350 CC12350‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

This type of problem, where you need to keep track of key/value pairs (county/map #), is best organized in a dictionary, where for each key (county) you increment the value (map #). See: 5. Data Structures — Python 2.7.15 documentation  Here's an example, not using the field calculator (sorry). In the field calculator, counter_dict should be global, and instead of appending to output_list, you'd return the value counter_dict[county]: county_list = ['Marin', 'Napa', 'Napa', 'Marin', 'Marin', 'Napa', 'Marin', 'Marin', 'Napa', 'Napa', 'Napa', 'Napa', 'Marin', 'Napa', 'Marin', 'Napa', 'Marin', 'Marin', 'Napa', 'Marin'] counter_dict = {} output_list = [] for county in county_list:     counter_dict[county] = counter_dict.get(county, 0) + 1     output_list.append([county, counter_dict[county]]) output_list = [['Marin', 1], ['Napa', 1], ['Napa', 2], ['Marin', 2], ['Marin', 3], ['Napa', 3], ['Marin', 4], ['Marin', 5], ['Napa', 4], ['Napa', 5], ['Napa', 6], ['Napa', 7], ['Marin', 6], ['Napa', 8], ['Marin', 7], ['Napa', 9], ['Marin', 8], ['Marin', 9], ['Napa', 10], ['Marin', 10]]‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...
