I'm not sure if this is the right place to put this question. If not, please let me know. I am trying to find the angle between adjacent lines in a single layer. I plan to accomplish this by subtracting the incidence angle of one line from that of its adjacent line. The lines come from polylines split at vertices, so the start coordinates of one line exactly match the end coordinates of another line. I have a field with the incidence angle for each line, a field with the begin xy of the line, and a field with the end xy of the line. I am trying to figure out how to have a script loop through the table, find the line whose beginningxy matches the endxy of the current line, and subtract the angles. I am not very familiar with Python so I would greatly appreciate guidance. Thanks!

Hello, I am working with a massive streets database, in which each street is broken into segments at each cross street. My work involves editing groupings of these streets at a time (for example, along "5th" from street A to street F) and while manual selection of those segments is certainly possible it is very tedious. I have been using Select by Attributes as well as the find option. I was thinking a program that selected only the segments of "5th" between Street A and Street F would be fantastic, although I don't know if anything similar to this exists or if it would be relatively straightforward to write. Does anyone have any suggestions for automating/speeding this process?
