Problem 1

# median test grade of a class
classScores = [96,94,83,85,85,85,87,79,88,76,79,81,93,81,66,93,96,83,83,84,100,96,85,79,79,79,79,13,95,55]
n = len(classScores) # size of class
classScores.sort() # simple, default sorting algorithm
if n % 2 == 0:
    median = (classScores[int(n/2)-1]+classScores[int(n/2)])/2 # average the middle two elements
else:
    median = classScores[n//2] # n//2=(n-1)/2 here
print(f"The median score is {median}")

The median score is 83.5

Problem 2

# simple game using random numbers
# does not use global variables, but passes in guessCount every time it is called
import random
num = random.randint(1,1000)
def userGuess(guessCount): # guessCount will be initialized at 0 at the end
    try:
        guess = int(input("Enter a guess between 1 and 1000!"))
        validate(guess,guessCount) # use the guess and pass in guessCount to see if user input is right
    except ValueError: # when an integer is not entered
        print("Please try again.")
        userGuess(guessCount) # try it again
def validate(guess, guessCount): # arguments of user's guess and guessCount
    guessCount += 1 # add one to the guessCount no matter what
    if guess > num: # cases and recursion if the guess is not right
        print("Too high.")
        userGuess(guessCount)
    elif guess < num:
        print("Too low.")
        userGuess(guessCount)
    else:
        print("Correct! Good job!")
        print(f"You guessed {guessCount} times.") # print out how many guesses the user made
print("I'm thinking of a number between 1 and 1000. Can you guess it?")
userGuess(0)

I'm thinking of a number between 1 and 1000. Can you guess it?
