lists and list item matches (ghost wodgame)

[Baba]

Hi

query level: beginner

as part of a learning exercise i have written code that:

a) asks for a single letter input (assumption: only 1 letter wil be
entered)
b) adds that letter to list1 and then goes through list2 and checks:

1) if any item in list2 starts with list1 > if False: break
2) if list1 == any item in list2 > if True: break

c) start again until 2) is True

wordlist = ['hello', 'bye']
handlist = []
letter = raw_input('enter letter: ')
handlist.append(letter)
hand = "".join(handlist)
for item in wordlist:
if item.startswith(hand):
while item.startswith(hand):
if hand not in wordlist:
letter = raw_input('enter letter: ')
handlist.append(letter)
hand = "".join(handlist)
else: break
else: break
print 'you loose'

this code works but can it be optimised? i have the feeling that my
nesting of IF, WHILE and FOR statements is overkill?

Yes it is overkill. Especially the else:break from the while loop
makes it difficult to follow the logic. Also the program breaks down
if I use the following word list:

wordlist = ['hello', 'hamburger', 'bye']enter letter: h
enter letter: a
you loose

I am not going to post any spoilers but I wrote your program using one
while loop and one generator expression for a total of 5 lines. My
version might be a bit too advanced but you should still be able to do
it using only one while, one for and one if instead.
