topic Re: Is there a way to use Python to select between two different line layers (specifically, lines that are connected to each other) AND specify which attributes I want to select by? in Python Questions https://community.esri.com/t5/python-questions/is-there-a-way-to-use-python-to-select-between-two/m-p/627899#M48909 <HTML><HEAD></HEAD><BODY><P>Thanks for taking a look at my question, Joshua. The different pressure classification levels are 1, 2, 5, 6, 7, and 8. These are the same classes in both the service line layer and the main line layer. I essentially need to find all the service lines that don't match the main lines regarding pressure classification. I'll try to gather some samples later this afternoon. </P></BODY></HTML> Thu, 20 Jul 2017 13:29:15 GMT MichaelHeing 2017-07-20T13:29:15Z Is there a way to use Python to select between two different line layers (specifically, lines that are connected to each other) AND specify which attributes I want to select by? https://community.esri.com/t5/python-questions/is-there-a-way-to-use-python-to-select-between-two/m-p/627896#M48906 <HTML><HEAD></HEAD><BODY><P>I have two line layers in a gas distribution gdb&nbsp;and I want to select all of the <EM>class 6 </EM>lines that are connected to a <EM>class 5 main </EM>line, <EM>class 2 </EM>lines are connected to a main line that is NOT<EM> class 2</EM>, etc. Specifically, it is the 'connected to' aspect of this that I cannot figure out. </P></BODY></HTML> Wed, 19 Jul 2017 13:08:56 GMT https://community.esri.com/t5/python-questions/is-there-a-way-to-use-python-to-select-between-two/m-p/627896#M48906 MichaelHeing 2017-07-19T13:08:56Z Re: Is there a way to use Python to select between two different line layers (specifically, lines that are connected to each other) AND specify which attributes I want to select by? https://community.esri.com/t5/python-questions/is-there-a-way-to-use-python-to-select-between-two/m-p/627897#M48907 <HTML><HEAD></HEAD><BODY><P>I believe the easiest way to approach this would be to create a dictionary with keys of all the points which represent connections between pipes, and a value that is a list of all the&nbsp;pipe classes which connect at that point. Then for each line, check the points that touch the line for the class value matching your criteria for that selection.&nbsp;</P></BODY></HTML> Wed, 19 Jul 2017 19:18:04 GMT https://community.esri.com/t5/python-questions/is-there-a-way-to-use-python-to-select-between-two/m-p/627897#M48907 ClintonDow1 2017-07-19T19:18:04Z Re: Is there a way to use Python to select between two different line layers (specifically, lines that are connected to each other) AND specify which attributes I want to select by? https://community.esri.com/t5/python-questions/is-there-a-way-to-use-python-to-select-between-two/m-p/627898#M48908 <HTML><HEAD></HEAD><BODY><P>It would be helpful if you could provide some more information, maybe even a sample dataset.&nbsp; It is the "etc." part that makes me hesitate because what I suggest will likely vary if there are 3 conditions or 30 conditions.</P></BODY></HTML> Wed, 19 Jul 2017 19:28:23 GMT https://community.esri.com/t5/python-questions/is-there-a-way-to-use-python-to-select-between-two/m-p/627898#M48908 JoshuaBixby 2017-07-19T19:28:23Z Re: Is there a way to use Python to select between two different line layers (specifically, lines that are connected to each other) AND specify which attributes I want to select by? https://community.esri.com/t5/python-questions/is-there-a-way-to-use-python-to-select-between-two/m-p/627899#M48909 <HTML><HEAD></HEAD><BODY><P>Thanks for taking a look at my question, Joshua.
