Problems with Randomized Guessing Game - python-3.x

Question

this is my first post here so bear with me. I decided to take an online coding course to help me learn the basics of Python, up until now it's been great. Difficult, but manageable. Well, it appears I've hit a wall. I am trying to write a program that randomly generates a word from a wordlist.txt file then allow the user to guess letters in said word with a set amount of guesses.
'''
import random
def pick_word_from_file():
file = open("wordlist.txt", 'r')
words = file.readlines()
file.close()
word = random.choice(words).strip("\n")
return word
word = pick_word_from_file()
hidden_word = len(word)
num_of_guesses = 5
print('Welcome to Guess a Letter!')
print('Your word has {} letters.'.format(hidden_word))
print('You have {} guesses left!'.format(num_of_guesses))
new_word = []
for i in range(hidden_word):
new_word.append('_')
print(new_word)
while num_of_guesses > 0:
guess = input('Take a guess!')
if guess in word:
num_of_guesses = num_of_guesses - 1
pass
else:
num_of_guesses = num_of_guesses - 1
print('Oof! looks like that letter is not in the word!')
if num_of_guesses == 0:
Print('All out of guesses!')
'''
What I am currently struggling with is replacing the hashed out letter of the randomized word with the correct guess. Every time is a guess is correct it should output that letter in the correct space for the word.

Answer 1

My approach to this problem is storing the indices of each character in a dictionary like this.
>>> word = 'python'
>>> word_loc = {}
>>> for idx, char in enumerate(word):
... word_loc[char] = word_loc.get(char, []) + [idx]
...
>>> word_loc
{'p': [0], 'y': [1], 't': [2], 'h': [3], 'o': [4], 'n': [5]}
Next, update each index accordingly when the guess is correct.
>>> while True:
... guess = input('Take a guess!\n')
... if len(guess) != 1:
... print('Invalid guess!')
... elif guess in word:
... print('correct guess!')
... for idx in word_loc[guess]:
... new_word[idx] = guess
... print(new_word)
... if ''.join(new_word) == word:
... print('Congratulations! You've guessed the word correctly!')
... break
... else:
... num_of_guesses -= 1
... print('Incorrect guess! Remaining attempts = {}'.format(num_of_guesses))
... if num_of_guesses == 0:
... print('You failed to guess the word! Aborting program!')
... break
...
Take a guess!
s
Incorrect guess! Remaining attempts = 4
Take a guess!
r
Incorrect guess! Remaining attempts = 3
Take a guess!
p
correct guess!
['p', '_', '_', '_', '_', '_']
Take a guess!
y
correct guess!
['p', 'y', '_', '_', '_', '_']
Take a guess!
c
Incorrect guess! Remaining attempts = 2
Take a guess!
h
correct guess!
['p', 'y', '_', 'h', '_', '_']
Take a guess!
n
correct guess!
['p', 'y', '_', 'h', '_', 'n']
Take a guess!
s
Incorrect guess! Remaining attempts = 1
Take a guess!
a
Incorrect guess! Remaining attempts = 0
You failed to guess the word! Aborting program!
