Hangman Game Program Error

gulshan212

Hello this is Gulshan Negi
Well, I am making a Hangman Game in Python but it shows some error at the time of its execution.

Here is my source code:

import random
def select_word():
words_in_computer_memory = ['magazine','stars','computer','python','organisation']
word = random.choice(words_in_computer_memory)
return word
def is_gussed(word, guessed_letter_list):
count=0
for letters in word:
if letters in guessed_letter_list:
count+=1
if count==len(word):
return True
else:
return False
def guessed_word(word, guessed_letter_list):
string=""
for key in word:
if key in guessed_letter_list:
string+=key
else:
string+="_ "
return string
def available_letters(guessed_letter_list):

string=""
count=0
s='abcdefghijklmnopqrstuvwxyz'
for letter in s:
    if letter in guessed_letter_list:
        count+=1
    else:
        string+=letter
return string

def hangman_game(word):
length=len(word)
print('''------------------WELCOME TO HANGMAN GAME---------------------------
O

''')
print("The word you have to guess is of ",length, "letters long.")
chances=2*len(word)
i=0:
guessed_letter_list=[]
while (chances!=0):

    if word!=guessed_word(word, guessed_letter_list):
        print("You Got", chances, "Chances.")
        print("Letters you can enter should be from these ",available_letters(guessed_letter_list))
        guess=input("ENTER A LETTER ")
        print('\n'*50)

        guessInLowerCase = guess[0].lower()      
        if guessInLowerCase  in guessed_letter_list:
            print("SORRY! YOU HAVE GUSSED THIS LETTER ALREADY! ",guessed_word(word, guessed_letter_list))
        elif guessInLowerCase not in word: 
            print(" SORRY! THE LETTER IS NOT IN WORD",guessed_word(word, guessed_letter_list))
            chances-=1
        else:
            guessed_letter_list.append(guessInLowerCase)
            print("NICE YOU GUSESSED THE RIGHT LETTER! ",guessed_word(word, guessed_letter_list))

    elif word==guessed_word(word, guessed_letter_list):
        print("YOU WON!")
        break

else:
    print('''
    ********************************************

YOU LOSS!!
O
/|\
/ \
******************************************''')
print('The word was',word,)

word = select_word()
hangman_game(word)

I also check and took reference from here, can anyone give their suggestion on this.
Thanks
