I need someone to write me a Python script

I need someone to write me a Python script that extracts all cross-points (nodes) and connecting streets (edges) from open street maps for a given city. The data needs to be such that one can find the shortest path from A to B (not part of the task). Ideally, the extracted data looks like: nodes = 12031 edges = { (1,2): ("Rue du Faubourg Poissonnière", "200m"), # Street segment, first direction (2,1): ("Rue du Faubourg Poissonnière", "200m"), # Second direction (2,3): ("Rue du Faubourg Poissonnière", "400m"), (3,2): ("Rue du Faubourg Poissonnière", "400m") (2,4): ("Rue de l'Échiquier", "30m") ## One street segment ### ... more segments } If the above does not make sense to you, then this isn't a task for yo
