Python 3 - 刽子手游戏 using.txt doc word bank

Question

Im trying to make a hangman using a word bank stored on a.txt document but I'm so confused and just going round in circles.

Can anyone point me in the right direction? My code so far is below. Cheers!

#Word list
from random import choice

word = with open("words.txt") as f:
    word_list = f.read().splitlines()

#title
print("Welcome to Hangman! You have 7 lives to guess.")

#word generator
hidden_word = random.sample(words,1)

if(hidden_word[0]):
    print("The length of the word is: " , len(hidden_word[0]))

#parameters
guesses=0
guessed = []
word = []

#Game
for x in range(len(hidden_word[0])):
    word.append(' * ')

while guesses < 7:
    guess = input("Please enter your next guess: ""\n")

    if(guess in hidden_word[0]):
        print("The letter is correct.")
        for index, letter in enumerate(hidden_word[0]):
            if letter == guess:
                word[index] = guess
        guessed.append(guess)

    else:
            print("That letter is incorrect.")
            guesses=guesses+1
            guessed.append(guess)

    print("Please enter your next guess:")
    print("So far, you have answered - %s"%''.join(word))
    print()

    if ''.join(word) == hidden_word[0]:
        break

#Game finish
if guesses==7:
    print("You lose. The word was:" , hidden_word[0])
else:
    print("Congratulations, you won!")

Here is a tested working bit of code. You'll find the main issues were with your import, an incorrect open statement, incorrect indexing of non-list variables... in many cases, you were indexing a string, which was clearly not what you wanted to be doing.

import random

# note: get in the habit now of putting your code in a function and not polluting the global scope
# we can test the code using a test word in the event that a stackoverflow contributor doesn't have a words.txt file at hand :P
def main(test_word = "banana"):
    # if there is no words.txt, we will use the test word
    try:
        with open("words.txt") as f:
            word_list = f.read().splitlines()
    except IOError:
        word_list = [test_word]

    # we use random.choice, as we have a list and we want a random word from that list
    # we also want to make sure we put the word and our guesses into the same case, so here I chose lower case
    hidden_word = random.choice(word_list).lower()

    print("Welcome to Hangman! You have 7 lives to guess.")
    print("The length of the word is: " , len(hidden_word))

    failures    = 0
    guessed     = []
    # python is cool, and you can get repeat characters in a list by multiplying!!
    word        = ['*'] * len(hidden_word)

    while failures < 7:
        print("The word is: %s" % ''.join(word))

        try:
            guess = input("Please enter your next guess: ""\n")[0].lower()
        except IndexError:
            # just hitting enter will allow us to break out of the program early
            break

        if guess in guessed:
            # ignore an already guessed letter
            continue
        elif guess in hidden_word:
            print("The letter is correct.")
            for index, letter in enumerate(hidden_word):
                if letter == guess:
                    word[index] = "%s" % guess
        else:
            print("That letter is incorrect.")
            failures += 1
        guessed.append(guess)

        if ''.join(word) == hidden_word:
            break

    if failures == 7:
        print("You lose. The word was:" , hidden_word)
    else:
        print("Indeed, the word is:", hidden_word)

if __name__ == "__main__":
    main()

Sample Usage

Welcome to Hangman! You have 7 lives to guess.
The length of the word is:  6
The word is: ******
Please enter your next guess: 
n
The letter is correct.
The word is: **n*n*
Please enter your next guess: 
b
The letter is correct.
The word is: b*n*n*
Please enter your next guess: 
a
The letter is correct.
Indeed, the word is: banana

Answer 2

Yes, the file importing was a bit of a sticking point for me. Definitely need to have another look at this.

Looking at your answers, it makes a lot of sense but a reread would be smart.

Answer 3

I think you have made some mistakes while importing random, and while you use with you should not declare it to a variable This should do it

import random

with open("words.txt") as f:
    word_list = f.read().splitlines()

#title
print("Welcome to Hangman! You have 7 lives to guess.")

#word generator
hidden_word = random.sample(word_list,1)

if(hidden_word[0]):
    print("The length of the word is: " , len(hidden_word[0]))

#parameters
guesses=0
guessed = []
word = []

#Game
for x in range(len(hidden_word[0])):
    word.append(' * ')

while guesses < 7:
    guess = input("Please enter your next guess: ""\n")

    if(guess in hidden_word[0]):
        print("The letter is correct.")
        for index, letter in enumerate(hidden_word[0]):
            if letter == guess:
                word[index] = guess
        guessed.append(guess)

    else:
            print("That letter is incorrect.")
            guesses=guesses+1
            guessed.append(guess)

    print("Please enter your next guess:")
    print("So far, you have answered - %s"%''.join(word))
    print()

    if ''.join(word) == hidden_word[0]:
        break

#Game finish
if guesses==7:
    print("You lose. The word was:" , hidden_word[0])
else:
    print("Congratulations, you won!")
