Lab 6: Functions

Points Possible: 100

Due: Thursday, October 10th

In this lab, we will write programs using functions.

Submission:

1. Submit a Python file for each of the programs.

Program 1: Calculate Discount

Write a function calculate_discount that takes as input 2 parameters: price, discount rate (in %), and return the discount.

Write a test program to read the price and discount rate values (using input statements outside the function) and display the discount by calling the calculate_discount function (invoke function) and printing the return value of the discount.

Save the program is discount.py and attach it to the Blackboard lab assignment.

Program 2: Divide By

Write 3 functions with the requirement as mentioned below:

• Write a function divBy5(num) that takes as input a number and returns True if the number is divisible by 5. It returns False otherwise.
• Write a function divBy6(num) that takes as input a number and returns True if the number is divisible by 6. It returns False otherwise.
• Write another function divBy5and6(num) that takes as input a number num and calls divBy5(num) and divBy6(num). The function returns True if the output/returned values from both divBy5(num) and divBy6(num) are True. It returns False otherwise.

Write a test program to read a number from the user (using an input statement outside the functions) and call the divBy5and6(num) function (invoke function) and printing the return value from the function.

Save the program is divideby.py and attach it to the Blackboard lab assignment.

Grading Rubric for each of the functions:

Grading	Points Possible
Appropriate docstring and comments	5
Input and output	5
Computation	10
Function invocation	5

TOTAL 25 points for each function
