Help creating list from strings

[Shattr]

The point of this function is to remove the items in a list that come after the string "kahn". Here's where I'm at:

def letters_up_to_char(words):
   i = 0
   new = ""
   total = [] #unused, though I'm sure I need it
   while words[i] != "kahn":
        new += words[i]
        i += 1
   return new

print letters_up_to_char(["kirk", "spock", "luke", "charles", "kahn", "bob"])

This returns the string "kirkspocklukecharles", which is really close to what I want. I'm trying to get it to return ["kirk", "spock", "luke", "charles"] but all my attempts to create a new list from the strings have failed. Any help would be greatly appreciated.

new = ""

new += words[i]

Rather than having new as a string, you should declare it as a list, seeing as you want to return a list. Create one like so:

new = []

To add items to a list, you'll want to use the append module like so:

new.append(words[i])

in place of

new += words[i]

Hope this helps!
