1 A program is being developed to show the average daily temperature and add up the
costs of buying ice cream.
• It displays each temperature stored in an array of temperatures.
• It adds up all the ice cream costs entered by the user, until the user enters 0.
• It then calculates a discount. When the total cost is over 100.00, the discount is
10%. Otherwise, the discount is 5%.
Open file Q01.py
Amend the lines at the bottom of the code to give the:
• name of a constant used in the program
• name of an array used in the program
• line number of an initialisation of a variable with a real number
• line numbers for a selection construct
• line numbers for a repetition construct
• line numbers for an iteration construct
• line number for an instruction that outputs information to the screen.
Do not add any additional functionality.

2 A program is written for an exercise routine. It displays the names of warm-up
exercises, stored in an array. The user enters a number. That number of exercises is
selected randomly from the array and displayed.
Open file Q02.py
Amend the code to:
• fix the syntax error on original line 4
import randum
• fix the syntax error on original line 16
for exercise in exerciseTable
• complete original line 20 to generate a random number between 0 and 4
index = random.
• complete original line 8 to make the exercise names be string data types
exerciseTable = [ "squats", "planks", pushups,
"lunges", "burpees"]
• fix the IndexError on original line 21
name = exerciseTable[index + 1]
• fix the NameError on original line 22
print (naime)
fix the logic error on original line 19 that causes one less exercise to be printed
•
than is asked for
for count in range (numExercises - 1):
• use white space to improve the readability of the code.
Do not change the functionality of the given lines of code.
Do not add any additional functionality.
