i was creating a simple guessing game where in the guess is matched to the original string and completes the word.
Encountering 2 errors.
1. When wrong guess is made, the else condition is not called and python returns an error.
Traceback (most recent call last):
File "C:/Users/PycharmProjects/Study2.py", line 12, in <module>
if w.index(x):
ValueError: 'b' is not in list
2. The first letter is not replaced in the guessed word inspite of guessing correctly.

print("=====Hangman =====\nGuess the letters to fill the blanks")

w = ["o", "r", "a", "n", "g", "e"]
b = ["_", "_", "_", "_", "_", "_"]
wrong = 0

while b != w and wrong <=6:
    print(b)
    x = input("Enter your guess:  ")
    if w.index(x):
        i = w.index(x)
        b[i] = x
    else:
        wrong += 1

if wrong == 6:
    print("Your are out of guesses")

Python string method index() determines if string str occurs in string or in a substring of string if starting index beg and ending index end are given. This method is same as find(), but raises an exception if sub is not found

Hi @deanhystad,
Thank you for the reply. Find() is not a list attribute. I am using a list of strings to enter guesses. As just a string, I was unable to replace a position in the string.

Answer is the same though. When the guess is not in the list index throws an exception.

There is no reason the word can't be a string. The word doesn't change. Here's a "Wheel of Fortune" version of Hangman. It matches multiple positions if a letter occurs in the word more than once.

import random

def find_all(letter, word):
    """Return array of indices where letter appears in word"""
    return [i for i, x in enumerate(word) if x == letter]

def hangman(word):
    """Play a game of hangman"""
    # Initialize to empty board
    word = word.upper()
    count = len(word)
    letters = ['_']*count
    remaining = count
    misses = 0

    # Begin play.  Play continues until player guesses the word or runs out of misses
    while remaining > 0 and misses < 6:
        """Draw the letters and remaining misses.  Get letter guess"""
        print(' '.join(letters))
        letter = input(f'Misses = {misses}.  Enter letter: ').upper()

        """Find all matches"""
        matches = find_all(letter, word)
        if len(matches) == 0:
            misses += 1  # No match
        else:
            for i in matches:
                letters[i] = letter # Replace blanks with letter
            remaining -= len(matches)

    # Did they win?
    if remaining == 0:
          print('Congratulations!')
    print(f'The word was "{word}"\n')
        

# Allow for multiple plays
words = ['Orangatan', 'Hippopotomus', 'Giraffe', 'Cheetah', 'Chimpanzee']
random.shuffle(words)

# Play until out of words or the player wants to quit.
first = True
for word in words:
    if not first:
        if input('Would you like to play again? ').upper()[0] != 'Y':
              break
    first = False
    hangman(word)

@deanhystad thanks for code. I m still understanding the functions and parameters in it. its pretty awesome. i was having trouble using strings.

as for my code, i removed index function from the if condition and rewrote the code. its working now. Both errors are addressed.

print("=====Hangman =====\nGuess the letters to fill the blanks")
w = ["f", "l", "a", "m", "e", "s"]
b = ["_", "_", "_", "_", "_", "_"]
wrong = 0

while b != w and wrong <6:
    print(b)
    x = input("Enter your guess:  ")
    if x in w:
        i = w.index(x)
        b[i] = x
    else:
        wrong += 1
        print("Wrong guesses : " + str(wrong))
        if wrong == 6:
            print("Your are out of guesses")
if b == w:
    print(b)
    print("\n You Win !!")

Output:
=====Hangman =====

Very nice!

I have made hangman with little more interactive and can play over and over.

hi @deanhystad

i have basically taken apart the wheel of fortune HANGMAN code you sent. Since i am just stating off in python it took me a while. But i learnt quite a few things which is uniquely interesting about python, specially list comprehension.
And i have understood that strings cannot be re-assigned as per index. Even in the code the string is converted into a list(array) and dealt with therein. while strings have a great many functions, it is not possible to reassign a character in the string by index.
Please let me know if you think otherwise.

Error:
Traceback (most recent call last):
  File "C:/Study/App1_1/Study2.py", line 15, in <module>
    b[i] = x
TypeError: 'str' object does not support item assignment

@Shahmadhur13 thank you for the code. i must say you have maintained most of the operation as a string.
it is quite interactive.
you have put in a lot of effort for the code. During my lessons i read somewhere its best to keep code to minimum. while your code internal logic is approx 30 lines. The code sent by @deanhystad is only 10 lines.
i am not counting the interactive menu code. if i understand correctly you have used all the string functions to create this program, which is why it is long. but in assigning the index you have used a list(array). so if you start using the letters and words as array elements from the beginning, you could save a lot of code lines.

this is just my observation. each persons logic is unique.
let me know what you think.

Yes sir, you're right.
I know I have far more code lines than actually needed.
For me, right now is to get things done with whatever I have learned till now. "enumerate" function i didn't learn till i see above post. Enumerate function only can trim my code line by approximately 10 lines.
I will focus on optimization of python code once i completely learn all basic functions.
Thank you for your advice. I will surely keep this in mind.

Added a piece to Shahmadhur13's code. Replace the data[] part with

file = 'words_alpha.txt'
data = []
count = 0
with open(file,'r') as words:
    for word in words:
        data.append(word.replace('\n', ''))

and using the link to the text file below you will have a list of words counting 370,104 words.
