1) After the following code executes, what elements will be members of set3?
set1 = set([\'d\', \'e\', \'f\'])
set2 = set([\'a\', \'b\', \'c\', \'d\', \'e\'])
set3 = set2.difference(set1)
print(set3)

2) Write a statement that prints average score of Ethan.  
scores = {\'Kylie\':[88, 92, 100], \'Peter\':[95, 74, 81],
\'James\': [72, 88, 91], \'Ethan\':[70, 75, 78]}

3) Identify at least five errors in the following code segment and re-write in correct form:
Import rand
main def ()
/* comments: guessing the throw of a die*/
y = random.uniform(1,6)
x = input(int(‘Enter a number from 1 to 6’))
if y = x
print(Sorry you have guessed wrong. Please try again)

    else if y != x
    print(‘You have guessed correctly”)

main()

4) Convert the following to a while-loop construct. You need not use all the defined variables.
def main ():
sum = 0
number_1 = input(“Enter a number”)
number_2 = input(“Enter a number”)
number_3 = input(“Enter a number”)
sum = number_1+number_2+number_3
print(sum)
main()

Solution

1.

set1 = set([\'d\', \'e\', \'f\']) // Set contains def
set2 = set([\'a\', \'b\', \'c\', \'d\', \'e\']) // Set contains abcde
set3 = set2.difference(set1)

// set3 contains, the strings of set2 which not in set1.
print(set3) // It prints abc

Output :

abc
