Create a Function for me on Python 3.6.5

I need someone who is skilled in Python that can help me with a program that need to be able to give the best possible position to place WiFi Routers to get the best Network Coverage in a given building. This will be done with using Matrices in the function. If you read the Guide on the files I uploaded it will be easier to understand. As it explain exactly what is required in the program Below is the introduction to the problem. Introduction Who doesn't love wireless Internet? Millions of people rely on it for productivity and fun in countless cafes, railway stations and public areas of all sorts. For many institutions, ensuring wireless Internet access is now almost as important a feature of building facilities as the access to water and electricity. Typically, buildings are connected to the Internet using a fiber backbone. In order to provide wireless Internet access, wireless routers are placed around the building and connected using fiber cables to the backbone. The larger and more complex the building, the harder it is to pick router locations and decide how to lay down the connecting cables. Objective: Given a building floor plan, decide where to put wireless routers to maximize coverage and minimize cost. Building Floor Plans The building floor plans will be provided in text (.txt) files. Each character in these text files is either: a '.' - denoting a cell that requires wifi coverage a '#' - denoting a cell that is a wall a '-' - denoting a cell that is void (does not require wifi coverage) The [login to view URL] will describe the project in detail. Use the [login to view URL] file for the solution. Need it to be done on Monday 21/05/2018. Introduction Who doesn't love wireless Internet?
