Python Functions Assignment

Objectives

• You will learn to define functions
• You will learn to call functions with input parameters
• You will learn to test the data returned by functions

• HTTLACS: Ch 5 - More Functions

Directions

Create a file name "functionsPractice.py". In your file, complete the following exercises:

1. compare(a, b)
   • Define a compare(a, b) function that returns 1 if a > b, 0 if a == b, and -1 if a < b
   • Test your compare function with 3 different function calls. Make sure each gives you the expected result:
     • compare(5, 4)
     • compare(7, 7)
     • compare(2, 3)
2. hypotenuse(a, b)
   • Define a hypotenuse(a, b) function that returns the length of the hypotenuse of a right triangle given the lengths of legs a and b
   • Test your hypotenuse function with the following function calls. Make sure each gives you the expected result:
     • hypotenuse(3, 4)
     • hypotenuse(12, 5)
     • hypotenuse(7, 24)
3. f2c(t)
   • Define a function named f2c(t) that converts the temperature parameter t from Fahrenheit to Celsius and returns it.
   • If you don't remember the formula to convert, then look for it online!
   • Create your own function calls that test the function
4. c2f(t)
   • Define a function named c2f(t) that converts the temperature parameter t from Celsius to Fahrenheit and returns it.
   • If you don't remember the formula to convert, then look for it online!
   • Create your own function calls that test the function
