POPython- The Word Game "Ghost", File I/O, and List question
text
Body
copied!<p>I want to create computer for the word-game <a href="http://en.wikipedia.org/wiki/Ghost_%28game%29" rel="nofollow">Ghost</a>. However, I'm having problems thinking of a good way to deal with accessing the huge word list. Here's my current implementation (which doesn't work):</p> <pre><code>import os, random, sys, math, string def main(): #Contains a huge wordlist-- opened up for reading dictionary = open("wordlist.txt", "r") wordlist = [] win= 0 turn= 0 firstrun = 0 word = "" #while nobody has won the game while win==0: if turn == 0: #get first letter from input foo = raw_input("Choose a letter: ")[0] word+=foo print "**Current word**: "+ word #Computer's turn turn = 1 if turn == 1: #During the first run the program gets all definitively #winning words (words that have odd-number lengths) #from the "dictionary" file and puts them in a list if firstrun== 0: for line in dictionary: #if the line in the dictionary starts with the current #word and has an odd-number of letters if str(line).startswith(word) and len(line)%2 == 0: wordlist.append(line[0: len(line)-1]) print "first run complete... size = "+str(len(wordlist)) firstrun = 1 else: #This is run after the second computer move for line in wordlist: #THIS DOES NOT WORK-- THIS IS THE PROBLEM. #I want it to remove from the list every single #word that does not conform to the current limitations #of the "word" variable. if not line.startswith(word): wordlist.remove(line) print "removal complete... size = "+str(len(wordlist)) turn = 0 if __name__ == "__main__": main() </code></pre> <p>I have demarcated the problem area in the code. I have no idea why it doesn't work. What should happen: Imagine the list is populated with all words that start with 'a.' The user then picks the letter 'b.' The target word then must have the starting letters 'ab.' What should happen is that all 'a' words that are in the list that are not directly followed with a 'b' should be removed. </p> <p>I also would appreciate it if somebody could let me know a more efficient way of doing this then making a huge initial list. </p>
