Determines whether a number is prime

	def test_prime(x):
	if x <2:
	print False
	elif x == 2:
	print True
	# maybe i'm being lazy but i couldn't think of a way to make 2 return as prime w/o doing this.
	else:
	for i in range(2,x-1):
	y = x%i

I'm having problems with the second tier if statement on tier 32

	from random import randint

	board = []

	for x in range(0, 5):
	board.append(["O"] * 5)

	def print_board(board):
	for row in board:
	print " ".join(row)

INSTRUCTIONS Write a for loop to go through the characters of the string s and print them. However! If a character is an 'A' or an 'a', print a capital 'X' instead. Note: You'll want to follow the thing you're printing with a comma (,) to prevent your output from including newlines. Check the Hint for more! Hint You can use the same for syntax, …

	s = "A bird in the hand..."

	# Add your for loop
	for x in s:
	if x == "A" or x == "a":
	print "X",
	else:
	print x,

The prompt: 2. Modifying each element in a list in a function This exercise shows how to modify each element in a list. It is useful to do so in a function as you can easily put in a list of any length and get the same functionality. As you can see, len(n) is the length of the list. Create a function called myFun that takes a single argument x (…

	n = [3,5,7]

	def myFun(x):
	z = []
	for i in x:
	z.append(i*2)
	print z

	myFun(n)

I'm not sure why this works, particularly line 8. I guess expected to need another for loop to run through stock.

	prices = {"banana" : 4, "apple" : 2, "orange" : 1.5, "pear" : 3}
	stock = {"banana":6, "apple": 0, "orange": 32, "pear" : 15}


	for z in prices:
	print z
	print "prices: "+ str(prices[z])
	print "stock: "+ str(stock[z])
	print
	print

I get this error: Traceback (most recent call last): File "python", line 9, in <module> File "python", line 7, in get_min NameError: global name 'balance' is not defined Oops, try again. Did you create a function called get_min? from the messageboard it seems other folks got it to work w/ similar code.

	def hotel_cost(nights):
	return nights * 140

	bill = hotel_cost(5)

	def get_min(balance, rate):
	return balance * rate

	print get_min(bill,.02)

Why does the first one work, but the second doesn't?

	pyg = 'ay'

	original = raw_input('Enter a word:')

	if len(original) > 0 and original.isalpha():
	word = original.lower()
	first = word[0]
	if first == "a" or "e" or "i" or "o" or "u":
	print "vowel"
	else:
