[sumo-user] Edge lenght

[Stefano N. <ste...@ho...>]

Dear Sumo Community,
I would like to ask how it is possible to retrieve the length of an edge through Python. Based on what I found here:
http://sumo.dlr.de/wiki/Tools/Sumolib
at the paragraph: "compute the average and median edge length in a plain xml edge file", I wrote the following code:
for edge in sumolib.output.parse('myNet.net.xml', ['edge']):
               if edge.id == myedgeid:
                              length = edge.length
But this solution is not working as the script is able to find effectively edge.id but that, through debugging I found that edge.length is an empty veriable. I looked a little through the internet but I got a little bit confused about the answer I found. How can I retrieve the length of a particular edge?

Thank you very much in advance
