Dear list,
out of "Thinking in Python" I take the following code, which
"takes a word and a string of required letters, and that returns True if
the word uses all the required letters at least once".
def uses_all(word, required):
for letter in required:
if letter not in word:
return False
return True
Now, I want to feed this code a list of words. This is what I have so far:
def uses_all(required):
fin = open('words.txt')
for line in fin:
word = line.strip()
for letter in required:
if letter not in word:
# print "False!"
return False
print word
required = raw_input("what letters have to be used? ")
print required
uses_all(required)
The code runs, but does not print the words. All I get it the output of
the 'print required' command:
da...@ubuntu:~/Documents/Tools/Python/Code$ python downey_9.5.py
what letters have to be used? zhg
zhg
aa
z
da...@ubuntu:~/Documents/Tools/Python/Code$
I realise that my loop fails to execute beyond the first word in the
list ("aa"), but why?
Thanks in advance for your insights!
David
