[Tutor] Algorithm

[kreglet]

Wayne,
 I appreciate your patience with me. I still can't get this to work:


from operator import itemgetter
class testwords:
	def __init__(self):
				self.lettercount={}
				self.inword=False
				self.mainword=""
				self.cmpword=""
				
def countletters(word):
	lc.lettercount = {}
	for letter in word:
		lc.lettercount[letter] =lc.lettercount.get(letter,0) + 1
	print sorted(lc.lettercount.iteritems(), key=itemgetter(1))

def comparewords(cmpword, mainword):
	for letter in cmpword:
		if mainword.get(letter):
			print letter, cmpword[letter], mainword[letter]
			if cmpword[letter] >mainword[letter]:
				lc.inword=False
			
		else:
		        if cmpword[letter] <=mainword[letter]:
				lc.inword=True


lc=testwords()

lc.mainword="batty"
lc.cmpword="bat"

countletters(lc.mainword)
mainword = lc.lettercount

countletters(lc.cmpword)
cmpword = lc.lettercount

comparewords(cmpword, mainword)

if lc.inword==True:
	print lc.cmpword + " IS in: " + lc.mainword
if lc.inword==False:
	print lc.cmpword + " IS NOT in: " + lc.mainword


This is confusing me:

lc.mainword="batty"
lc.cmpword="bat"


[('a', 1), ('y', 1), ('b', 1), ('t', 2)]
[('a', 1), ('b', 1), ('t', 1)]
a 1 1
b 1 1
t 1 2
bat IS in: batty

lc.mainword="batty"
lc.cmpword="byyt"

[('a', 1), ('y', 1), ('b', 1), ('t', 2)]
[('b', 1), ('t', 1), ('y', 2)]
y 2 1
b 1 1
t 1 2
byyt IS in: batty

if I put : 			if cmpword[letter] <=mainword[letter]:
				    lc.inword=True


on the same level as the else statement:
lc.mainword="batty"
lc.cmpword="bat"


[('a', 1), ('y', 1), ('b', 1), ('t', 2)]
[('a', 1), ('b', 1), ('t', 1)]
a 1 1
b 1 1
t 1 2
bat IS Not in: batty

Neither is: byyt

Isn't what comes after the else statment to catch if a letter is in the
cmpword that is not in the mainword?

lc.mainword="batty"
lc.cmpword="bst"

KeyError: 's'
