Skill set for this LAB:

• Understand and implement the Program Development Cycle
• Use Simple Functions
• Use Top-Down Design
• Use variables and assignment statements
• Use input and print functions
• Use basic arithmetic operations
• Save, run and submit programs

• Python Programming Practice

  In all programs:

  • You MUST use Top-Down Design
  • Each subtask MUST be a separate function
  • You MUST have function MAIN in your program.
  • You have to show me the program output BEFORE you PRINT the source file.

  See EXAMPLES BELOW BEFORE you start to write your programs

  • Modification of Program 3 Chpater 3 p. 114
  • Different Version of the program above
  • Question 8 from Chapter 3 p. 115
  • Question 1 from Chapter 3 p. 114

  Problem 1 (45 points): Write a Python program that promts the user to enter one number that indicates the radius of the circle. The program will calculate and print the diameter (2*radius) , circumference (2*pi*radius) and area (pi*radius*radius) of the circle. Use the value 3.14159 for PI. Write separate function for each task. Main function will be responsible for reading the input value and using functions your wrote to calculate diameter, circumference, and area of the circle.

  Problem 2 (40 points): Modification of program 6 on page 115. Write a function which calculates BODY MASS INDEX(BMI) of the person using the formula in the book on page 115 in the programming exercise 6. This function has two formal parameters, weight and height, and prints the BMI index. Write a Python program that prompts the user to enter weight and height of three different people and calculates BODY MASS INDEX(BMI) for each person using the function you wrote.

  Problem 3 (10 points) Modification of Program 7 p.115. Write a function that has two formal parameters, grams and rate, and prints the number of calories. Write a program that calculates calories from fat and calories from carbs for two people, based on the number of the fat grams and carb grams each person provided.

  Problem 4 (5 points) : See example In the Spotlight: future_value.py on pp. 62-63. Write a function that calculates the amount of money you have to deposit today in order to receive specific future value, taking in account annual interest rate and number of years money will appreciate. Write main function that reads required input and uses the function to calculate the amount of money you have to deposit today. Use the formula on p.62
