These tiny, simple files are derived from Zed Shaw's free online book _Learn Python the Hard Way_. These files accompany Zed's exercises 18 and 19, in which he introduces functions. I wrote a quiz for students to test themselves - see the URL at the top of each file here.

def myname():
	print 'Mindy'
	print 'McAdams'

def anyname(a, b):
	print a
	print b

myname()

anyname('Mindy', 'McAdams')

a = 5
b = 3
c = 2

def multiply(x, y):
	num1 = x * y
	num2 = num1 * x
	print num2

multiply(c, a)

multiply(b, c)

subtotal = raw_input("What is the total before tax and tip? ")
subtotal = int(subtotal) # convert string to integer

mytax = 0.09 # meals tax in Florida is 9%, in many cities 

mytip = 0.2  # assuming a 20% tip 

def restaurant_calc(base, tax, tip):
	sub1 = base * tax
	sub2 = base * tip
	total = base + sub1 + sub2
	print "$%.2f" % total
	# The format string  %.2f  gives you exactly 2 decimal places

restaurant_calc(subtotal, mytax, mytip)
