What is shown on screen after you execute the program below? What is the value of res, res_p, res_r, and res_pr?

def ave(a, b):

result = (a + b) / 2

def ave_p(a, b):

result = (a + b) / 2

print("p", result)

def ave_r(a, b):

result = (a + b) / 2

return result

def ave_pr(a, b):

result = (a + b) / 2

print("pr", result)

return result

res = ave(1, 2)

res_p = ave_p(1, 2)

res_r = ave_r(1, 2)

res_pr = ave_pr(1, 2)

What’s wrong with this code? How can you fix it?

def calc(n1, n2):

answer = n1 + (n1 * n2)

print(answer)

num = int(input("Enter the second number: "))

result = calc(2, num)

print("The result is:", result)

Evaluate the following method calls given the assignment s = "Computing is FUN!" Think about the input and output of each method. You’re not expected to know all methods for all types: if you haven’t seen some of these before, your best guess based on the name will probably be right!

(a) s.isupper() (b) s.upper() (c) s.endswith("FUN!") (d) s.count('i') (e) s.strip('!') (f) s.replace('i', '!') (g) s.split() (h) s.isdigit()
