I've been trying to dissolve streams, using orders programatically and I came across this VB script. The reason is that if I use ArcGIS dissolve, it merges the confluence of the same orders. I would appreciate if someone with the know-how can give some hints on how to implement this VB script using python.

Stream Order Dissolve VB Script

I think i also faced the same problem. example is , having a stream with order 1,2,3,4.when two streams with order 2 end at the begining of order 3 node, if you dissolve the streams using the order field , the two streams join together to form one single order 2 stream instead of 2 streams. – zaid Jan 22 at 8:02

Are you suggesting that all segments of the same order are a multipart polyline? If so use the MultipartToSinglePart tool. Apologies if this is not the case.
