Declaring and Defining the function

A set of statements, which performs a particular task is called a function. The program gains modularity by using function. The application is quite easy to understand, read, and edit when they are created with functions. The developer/programmer creates a function and uses main() to call the function. Once the function gets executed, the control is transferred to the main program.

Problem Statement: The mathematician Conway imagined a game, called game of life, which considered cells that are susceptible to reproduce, disappear, or survive when they obey certain rules. These cells are represented by elements on a grid of squares, where a grid has an arbitrary size. Thus, each cell (except those on the boundaries of the grid) is surrounded by eight squares that contain other cells. The rules are stated as follows: 1. Survival: Each cell that has two or three adjacent cells survives until the next generation.2. Death: Each cell that has at least four adjacent cells disappears (or dies) by overpopulation. Also, each cell that has at most one adjacent cell dies by isolation.3. Birth: Each empty square (i.e., dead cell) that is adjacent to exactly three cells gives birthto a new cell for the next generation.It is worth noting that all births and deaths occur at the same time during a generation. Write a program that simulates this game and displays all successive…

Python only** define the following function: 1. This function must add a task to a checklist, setting its initial value to False. It will accept two parameters: the checklist object to add to, and the task name to add. In addition to adding the task, it must return the (now modified) checklist object that it was given. There is one issue, however: a task cannot be added to a checklist if the name requested is already being used by another task in that checklist. In that case, this function must print a specific message and must return None Define addTask with 2 parameters Use def to define addTask with 2 parameters Use a return statement Within the definition of addTask with 2 parameters, use return _ in at least one place. Do not use any kind of loop Within the definition of addTask with 2 parameters, do not use any kind of loop.

If the returned value is equal to the given input value then it is an armstrong number.
