######################################################################################### #John Connor McLaughlin #Programming Assignment 3 #COP4531 #December 10, 2013 ######################################################################################### #INTRODUCTION# This python scripts are designed to be run using python3 #RUNNING THESE PROGRAMS# proj3.py: Run the program with python3 supplying a command line argument of the filename for the file containing the input, followed by Source Node and the k value for shortest reliable path i.e. python3 proj3.py input3.txt A 2 #EXPECTED INPUT# File containing list of edges to a graph in the format #comment line UD / D startVertex endVertex Weight startVertex endVertex Weight startVertex endVertex Weight startVertex endVertex Weight Each edge should be seperated by newline characters There should be no lines in the file with no characters on it There should be one comment line at the start of the file #EXPECTED OUTPUT# The program will output to a file out.txt. It will contain the shortest path from the source to each node It will contain the shortest reliable path results #Note Shortest Reliable Path doesn't work. Hopefully, this will be enough work that you give me some points.
