Hi, I'm Alex. I created this Python blog to show people the latest games and code I'm working on, along with explanations and examples for anyone looking to learn more about Python, CGI / server-side programming, or just internet game development in general. Let me know what you think, and thanks for visiting!

Sept 1, 2012 : hangman_game.py

Here's a breakdown of how the hangman_game.py source code works, in 6 easy steps...

Test if a new game should be initiated. If so, choose a new mystery word and initialize the game variables...

form = cgi.FieldStorage() mystery_word = form.getvalue('mystery_word') if len(mystery_word) < 4: import urllib2 website = 'http://alexspy.com' website = 'http://www.ssa.gov/oact/babynames/decades/names2000s.html' f = urllib2.urlopen(website) str1 = f.read(); f.close() def f(x): return x.isalpha() and not x.isupper() and len(x)>=4 and len(x)<=10 list1 = filter(f, re.findall(r"\S+",str1) + re.findall('(?msi)>(.*?)<',str1)) import random, math mystery_word = list1[random.randint(0,len(list1)-1)] mystery_display = ['-' for i in range(len(mystery_word))] wrong_guesses = 0 all_letters_guessed = '' guess_letter = ''

If not, then import the current game info and store as local variables...

else: mystery_word = form.getvalue('mystery_word') mystery_display = form.getvalue('mystery_display') wrong_guesses = int(form.getvalue('wrong_guesses')) all_letters_guessed = form.getvalue('all_letters_guessed') if all_letters_guessed == None: all_letters_guessed = '' guess_letter = form.getvalue('guess_letter') if guess_letter == None: guess_letter = '' mystery_display = list(mystery_display)

Check if the entered letter occurs in the mystery word, if so then update the mystery display to reveal the guessed letter, if not then increase the guess counter...

if len(guess_letter)==1: good_job = 0 guess_lower = guess_letter.lower() if guess_lower in mystery_word: good_job += 1 position = [m.start() for m in re.finditer(guess_lower,mystery_word)] for i in range(len(position)): mystery_display.pop(position[i]) mystery_display.insert(position[i],guess_lower) guess_upper = guess_letter.upper() if guess_upper in mystery_word: good_job += 1 position = [m.start() for m in re.finditer(guess_upper,mystery_word)] for i in range(len(position)): mystery_display.pop(position[i]) mystery_display.insert(position[i],guess_upper) if not good_job: wrong_guesses += 1 all_letters_guessed += guess_letter

Check if the game is over, if so, update comments accordingly...

if mystery_word == ''.join(mystery_display): comments = 'Congratulations... You Win!!!' elif wrong_guesses >= 6: comments = 'Your hangman is hung. You lose!! (The word was "' + mystery_word + '")' else: comments = ' '

Generate the hangman ASCII art based on how many incorrect guesses have been entered this game...

def store_hangman(incorrect_letters): g = len(incorrect_letters) body_parts = ["O","|","/","\\","'","'"] body_parts = body_parts[:g] + [" " for i in range(6-g)] return body_parts body_parts = store_hangman(all_letters_guessed)

Print the hangman display to HTML, and all essential game info as hidden CGI input...

print "Content-type:text/html\r\n\r\n" print '<html><body>' print '<h2 style="font-family:courier; font-size:16px; text-align:left;">' print " _____ <BR/>" print " | | <BR/>" print " | " + body_parts[0] + " " print mystery_display + " <BR/>" print " | " + body_parts[4] + body_parts[1] + body_parts[5] + "<BR/>" print " | " + body_parts[2] + " " + body_parts[3] + "<BR/>" print " | <BR/>" print " --- <BR/>" print ' Letters guessed: ' + all_letters_guessed print '<BR/>' print '<table><td width="330">' print '<form action="/cgi-bin/hangman_game_bluehost.py" method="post">' print 'Guess a letter: <input type="text" name="guess_letter" size="2" maxlength="2">' print '<input type="hidden" name="mystery_word" value="' + mystery_word + '" />' print '<input type="hidden" name="mystery_display" value="' + mystery_display + '" />' print '<input type="hidden" name="wrong_guesses" value="' + str(wrong_guesses) + '" />' print '<input type="hidden" name="all_letters_guessed" value="' + all_letters_guessed + '" />' print '<input type="submit" value="Enter" /> </form>' print '</TD><TD>' print '<form action="/cgi-bin/hangman_game_bluehost.py" method="post">' print '<input type="hidden" name="mystery_word" value=" " />' print '<input type="submit" value="New Game" /> </form>' print '</TD></table>' print comments print '</h2>' print '</body></html>'
