ok .... forget about python for a minute.

write down the steps you need to follow to solve the problem in plain 
english.

1) Get the list of hashes from a website
2) Brute force the hashes using a dictionary

But 2 needs a dictionary:

1) Load a dictionary
2) Get the list of hashes from a website
3) Brute force the hashes using a dictionary

So you need a function to load the dictionary (from a local file?), a 
function to get the list of hashes, a function to try and brute force a 
hash using the dictionary, and some logic to tie it all together.

global data: list of words, list of hashes

load_dictionary ( file )
	read the words from the file

get_hashes( url )
	read the hashes from the url

brute_force()
	do every hash in hashes
		do every word in words
			if md5( word ) is hash
				solved this hash!

load_dictionary( "dictionary file name" )
get_hashes( "http://www.website.tld/path/file.ext" )
brute_force()
