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…
Problem D. Durdle Game Using the function from the previous problem, write a function durdle_game(target) which takes in as an argument a single string that will be the target to guess, and lets the user attempt to guess the target word. Each time the user makes a guess, the function will print out the result of the previous function to tell the user how close they are. If the user guesses correctly, then the game is over. Have the function return the number of guesses that it took the user to get the correct answer. Examples (text in bold is returned, text in red is user input.): >>> durdle_game('trick') Welcome to Durdle! Enter a guess:touch GBBGB Enter a guess:trash GGBBB Enter a guess:truck GGBGG Enter a guess:trick GGGGG Congratulations, you got it in 4 guesses! 4 >>> durdle_game('stoop') Welcome to Durdle! Enter a guess:chart BBBBY Enter a guess:tones YYBBY Enter a guess:togas YYBBY Enter a guess:tofus YYBBY Enter a guess:stock GGGBB…

Which statement of the following is the most appropriate? Group of answer choices One good method for specifying what a function is supposed to do is to provide a precondition and postcondition for the function. One good method for specifying what a function is supposed to do is to provide a precondition and postcondition for the function. These form a contract between the programmer who uses the function and the programmer who writes the function. Using the assert function to check preconditions can significantly reduce debugging time, and the assertion-checking can later be turned off if program speed is a consideration.

***in python only*** use turtle function Define the concentricCircles function such that: It draws a series of concentric circles, where the first parameter specifies the radius of the outermost circle, and the second parameter specifies the number of circles to draw. The third and fourth parameters specify an outer color and an other color, respectively. The outer color is used for the largest (i.e., outermost) circle, and then every other circle out to the edge alternates between that color and the 'other' color. The difference between the radii of subsequent circles is always the same, and this difference is also equal to the radius of the smallest circle. Put another way: the distance between the inside and outside of each ring is the same. Define concentricCircles with 4 parameters Use def to define concentricCircles with 4 parameters Use any kind of loop Within the definition of concentricCircles with 4 parameters, use any kind of loop in at least one place.

For each function, describe what it actually does when called with a string argument. If it does not correctly check for lowercase letters, give an example argument that produces incorrect results, and describe why the result is incorrect. # 1 def any_lowercase1(s): for c in s: if c.islower(): return True else: return False # 2 def any_lowercase2(s): for c in s: if 'c'.islower(): return 'True' else: return 'False' # 3 def any_lowercase3(s): for c in s: flag = c.islower() return flag # 4 def any_lowercase4(s): flag = False for c in s: flag = flag or c.islower() return flag # 5 def any_lowercase5(s): for c in s: if not c.islower(): return False return True The code and its output must be explained technically whenever asked. The explanation can be provided before or after the code, or in the form of code comments within…
Explain how inline functions differ from normal functions when called in the background.
Complete the following TODO by defining a function called add_func(). Define a function called add_func() that takes two arguments. The function should adds the two arguments together using + and return the output. For example, if the input values for the arguments are 1 and 2, then 3 should be returned. Likewise, if the input arguments are "good" and " day", then "good day" should be returned. # TODO print(f"add_func output for 1 + 2: {add_func(1, 2)}") print(f"add_func output for good + day: {add_func('good',' day')}") todo_check([ (add_func(1,2) == 3,'add_func() did not return 3 when using input values 1 and 2.'), (add_func('good',' day') == "good day",'add_func() did not return "good day" when using input values "good" and " day"') ])
List all cases when inline functions have the opposite effect.
