We want to calculate cheapest route to deliver data in a network infrastructure where data transfer cost varies between devices. Create an application that calculates cheapest route between chosen devices in this network. Application should accept following command line arguments:

• path to file with network specification
• ID of source device
• ID of target device For example: script.py network.txt 10 89 Input file with network specification will define each connection in new line using format: You can safely assume that transfer cost between 2 devices is same in both directions. Application should write an output to stdout in format:

-> -> -> ... -> -> --- Example For input file in.txt with content: 0 30 1 0 70 4 0 10 8 0 10 9 1 90 4 1 40 7 2 50 3 2 40 5 2 90 6 2 100 8 4 100 7 4 70 8 4 50 9 5 100 6 6 70 7 7 10 9 and command line arguments "in.txt 2 7" application should print following output: 2 -> 8 -> 0 -> 9 -> 7--
