Hi Robert,

for displaying strings with variable content, string formatting is a 
real boon. See <http://docs.python.org/lib/typesseq-strings.html> for 
details.

But here is a bit to give you the idea:

 >>> def silly_example():
	name = raw_input('What is your name?\n')
	if name[0].isalpha():
		if name[0].lower() in ('aeiou'):
			char_type = 'a vowel'
		else:
			char_type = 'a consonant'
	else:
		char_type = "something other than a letter"
	print "Hello, %s. Your name begins with %s." %(name, char_type)

	
 >>> silly_example()
What is your name?
Brian
Hello, Brian. Your name begins with a consonant.
 >>> silly_example()
What is your name?
Alberto
Hello, Alberto. Your name begins with a vowel.
 >>> silly_example()
What is your name?
42
Hello, 42. Your name begins with something other than a letter.
 >>>


See if you can get somewhere with these ideas. If you get stuck, post 
some code, and someone will be glad to help more.

Best,
