Assignment #005c More Functions (Total Marks 12)

Objectives:

• Understand the structure for creating and defining a function
• Use return statements to control the flow of information from the function to the calling block
• Make use of input parameters to control the flow of information from the calling block to the function

4 Tasks 2 Problems

Task 1

Create a function that converts the price of Bitcoin into Canadian Dollars .
The function will require 2 input parameters:
float: amount of currency being converted

return: float value in Canadian Dollars
You will make use of a local variable called "currBTC"
currBTC shows that the conversion is 1 btc = 45000 cad

Sample assertions:

assert btcTocad(1) == 45000
(2 points)

Task 2

Create a function that determines the largest number in a list of values and returns it.
1 input parameter:
list: the numbers to be checked for the largest value

return: float value of the largest number

Sample assertions:
assert largest([3,10,3]) == 10
(2 points)

Task 3

Create a function that determines the length of a hypotenuse given the lengths of 2 shorter sides
2 input parameters
float: the length of one side of a right triangle
float: the length of the other side of a right triangle

return: float value for the length of the hypotenuse

Sample assertions:
assert hypotenuse(6,8) == 10
(2 points)

Task 4

Create a function that determines the area of a circle if given the radius
1 input parameter
float: radius

return: float area for the circle

note: Area of a circle is given by A = pi*(square of the radius)
You may want to use the math module to complete this problem

Problem 1

Create a function that converts from degrees F to degrees C or vice versa, depending on which initial unit is given 2 input parameters:
float: the number of degrees
string: the unit that you currently have: may be 'C' of 'F'

return: float the number of degrees of the other unit

Sample assertions:
assert convertTemp(10,'C') == 50
assert converTemp(32,'F') == 0
(2 points)

Problem 2

Create a function that determines if a triangle is scalene, right or obtuse.
3 input parameters:
float: one side
float: another side
float: 3rd side

return: 0 : triangle does not exist 1 : if the triangle is scalene 2 : if the triangle is right 3 : if the triangle is obtuse

Sample assertions:
assert hypotenuse(12,5,13) == 2
assert hypotenuse(5,3,3) == 1
assert triangle(5,15,12) == 3
assert triangle(1,1,4) == 0
(2 points)
