Project 1: Some Really Random Things Solution

In this project, you provide four Python functions that solve particular problems as outlined below. The problem-solving aspects of these are the same as the exercises at the ends of the labs so far. The only difference is that instead of typing your code in the web browser and executing it with shift-enter, you will type the code in your text editor application, save it to a file ending incalled random_functions.py, and execute it in the terminal application by typing "python ./<filenamerandom_functions.py" without quotes. All of your functions should be in a single file called "<your_idl1.py" without quotes. Jim's file would, for example, be called 930112267l1.py. Notice that after your id number is the lower-case letter 'L', as in labthat single file1.







Write a function that takes as a parameter a positive integer h and prints an isosceles triangle of asterisks. Your function must be called print_isosceles(h), and must not return a value. For example, print_isosceles(5) should print



*




***




*****




*******




*********




Write a function that takes as parameters three integers and computes and returns the median of the three. That is, for the three provided integers, return such that ≤ ≤ . Your function must be called median_of_three(a,b,c), and must not print anything to screen. For example, median_of_three(7, -3, 0) should return 0.



One way to define a circle is by the coordinates of the upper left hand corner of the smallest square that contains the circle, and providing the width of that square, which is equivalent to the diameter of the circle. Assume that coordinate 0,0 is the upper-left hand corner of the universe, and our coordinate system is relative to that point so that x coordinates increase to the right and y coordinates increase down.



Provide a function that takes as parameters origin_x and origin_y representing the coordinates of the upper left hand corner origin of the circle's bounding square rectangle, the diameter of the circle, and the x and y coordinates of a point somewhere in the same coordinate system. Your function should return True if the point is inside of the circle, and False otherwise. Your function must be called point_is_in_circle(origin_x,

























origin_y, diameter, x, y), and must not print anything to the screen. For example,




point_is_in_circle(5, 15, 100, 52, 61) should return True.




To use a function that is provided by Python, but not in the __main__ namespace, we use the import keyword. The statement



from random import randint




imports the function randint from the random library for use in your program. Typically (and in this project), we place all import lines at the top of the file, at the left margin.

The randint function takes two parameters and and returns an integer between and , inclusive so ≤ ≤ . Using the randint function, write a function that simulates a Pokéstop by returning items (represented as these exact strings) with the following probabilities:







'Poke Ball'
40%
'Great Ball'
22%
'Razz Berry'
12%
'Potion'
12%
'Super Potion'
7%
'Hyper Potion'
4%
'Revive'
2%
'Egg'
1%



Your function must be called pokestop(), and must not print anything to the screen. For example,




pokestop() should return the string 'Razz Berry' around 12 out of every 100 calls.




10% Bonus Opportunity




Successful, well-presented implementations of the above functions will receive full credit. For a bonus, replace the test invocations of your function with a loop that implements a menu system. Each time the loop runs, it should prompt the user with the choices of functions, and numbers or letters to select each. Upon selection of a function, the loop should prompt the user for the values of each parameter (if any are needed) and then call the specified function with the provided parameters, print any returned results, and cycle to the menu again. The last option on the menu should be to exit the program. If the user selects that option, change the value of the control variable in your while loop so that it is False. This will terminate the loop and your program will exit.







SUBMISSION EXPECTATIONS






















random_functions.py: A single Python file containing your four implementations and optionally the while-loop driven menu system. The four functions must be called




print_isosceles(h),




median_of_three(a,b,c),




point_is_in_circle(origin_x, origin_y, diameter, x, y), and pokestop().




Each function should either return a value or print to screen as specified, but never both.
