Lesson 3 - newbie exercise

Read the code in each section and do the following -

1. Add comments to explain the code
2. Suggest test data to test the code
3. Make the suggested changes.

The answers will only say what the code does and how to make the suggested change.

def convertCurrancy(amount, rate):
	return amount * rate

Suggested change - Write a new function called poundsToDollar(amount) which will convert pounds to dollars. It should use the convertCurrancy(amount, rate) to perform the calulation.

def poundsToDollar(amount):
	return convertCurrancy(amount, 1.5)

for i in range(10, 20)
	# hint - % is called modulus and will return the remainder of division. 
	# see related links for more help!
	if (i % 2) == 0:
		print i, " is even"
	else:
		print i, " is odd"
		

Suggested changes - create a new function called oddEven(start, end). Add the above code to that function and call the function with at least 2 sets of test data.

def oddEven(start, end):
	for i in range(start, end)
		# hint - % is called modulus and will return the remainder of division. 
		# see related links for more help!
		if (i % 2) == 0:
			print i, " is even"
		else:
			print i, " is odd"

oddEven (5, 10)
oddEven (8, 16)

def x(z,y):
	if z > y: return z
	else: return y

Suggested changes - Change the names to make it more readable. Copy the changed version and produce it's opposite. Then test it by combining the two functions together as much as possible

def max(z,y):
	if z > y: return z
	else: return y
	
def min(z,y):
	if z < y: return z
	else: return y
	
print max ( min ( 12, 18), min (8, 19))
