#Step 2

import random
word_list = ["aardvark", "baboon", "camel"]
chosen_word = random.choice(word_list)

#Testing code
print(f'Pssst, the solution is {chosen_word}.')

#TODO-1: - Create an empty List called display.
#For each letter in the chosen_word, add a "_" to 'display'.
#So if the chosen_word was "apple", display should be ["_", "_", "_", "_", "_"] with 5 "_" representing each letter to guess.

guess = input("Guess a letter: ").lower()

display = []
for i in range(0,len(chosen_word)):
    display.append("_")

#TODO-2: - Loop through each position in the chosen_word;
#If the letter at that position matches 'guess' then reveal that letter in the display at that position.
#e.g. If the user guessed "p" and the chosen word was "apple", then display should be ["_", "p", "p", "_", "_"].
for letter in chosen_word:
    for i in range(0,len(chosen_word)):
        if letter == guess:
            display[i] = guess

#TODO-3: - Print 'display' and you should see the guessed letter in the correct position and every other letter replace with "_".
#Hint - Don't worry about getting the user to guess the next letter. We'll tackle that in step 3.
print(display)

#

need help with TODO-2 plz

#

i want to replace the correct enrty in the display list with the letter of the chosen_word if the letter == guess

#

but i keep getting this

#

but i only want the 'a' to be in the 2nd entry of the list

#

how do i do this??

Okay, so why are you using 2 for loops for iterating over your word once? Letter will not be changed in your inner for lop and overwrite your entire list.

#

!d enumerate

stuck rockBOT Jul 4, 2024, 1:14 PM

#

enumerate


enumerate(iterable, start=0)```
Return an enumerate object. *iterable* must be a sequence, an [iterator](https://docs.python.org/3/glossary.html#term-iterator), or some other object which supports iteration. The [`__next__()`](https://docs.python.org/3/library/stdtypes.html#iterator.__next__) method of the iterator returned by [`enumerate()`](https://docs.python.org/3/library/functions.html#enumerate) returns a tuple containing a count (from *start* which defaults to 0) and the values obtained from iterating over *iterable*.

```py
>>> seasons = ['Spring', 'Summer', 'Fall', 'Winter']
>>> list(enumerate(seasons))
[(0, 'Spring'), (1, 'Summer'), (2, 'Fall'), (3, 'Winter')]
>>> list(enumerate(seasons, start=1))
[(1, 'Spring'), (2, 'Summer'), (3, 'Fall'), (4, 'Winter')]
```  Equivalent to...

This might be useful for you here

well i kinda want to go through each entry of the 'chosen_word'

#

so 0 is the 1st entry

#

and so if its equal to the guess

#

then display[0] would be replaced with the letter

#

thats my aim

mint garnet Jul 4, 2024, 1:16 PM

#

Yeah I understand what your code is supposed to do, but I'm saying you don't need to use 2 separate for loops when one would be enough.

rose aspen Jul 4, 2024, 1:16 PM

#

ok

mint garnet Jul 4, 2024, 1:17 PM

#

That is also the origin of your error, since once the letter == guess is True for the letter from your outer for loop, your inner for loop will overwrite your entire display list with guess

yh ok

#

so how can i do what i want to do

mint garnet Jul 4, 2024, 1:19 PM

#

Well I could give you a working solution if you want, but for your learning I think it would be better if you figured it out yourself.
Try removing your inner for loop, and maybe look into enumerate it might make this easier for you

#

||py for i, letter in enumerate(chosen_word): if letter == guess: display[i] = guess||
Here's a solution, but try to figure it out yourself first ^^

is there another way instead of using enumerate

#

using simpler lingo

mint garnet Jul 4, 2024, 1:19 PM

#

Yeah

rose aspen Jul 4, 2024, 1:20 PM

#

could u give me a hint for that plz

mint garnet Jul 4, 2024, 1:20 PM

#

Just iterate over your word extracting a letter using its index

rose aspen Jul 4, 2024, 1:20 PM

#

ok

mint garnet Jul 4, 2024, 1:20 PM

#

Then you can use the index variable to assign the respective position in display

rose aspen Jul 4, 2024, 1:20 PM

#

mint garnet Just iterate over your word extracting a letter using its index

would i need to use the range function?

mint garnet Jul 4, 2024, 1:21 PM

#

Yes

rose aspen Jul 4, 2024, 1:21 PM

#

ok

rose aspen Jul 4, 2024, 1:22 PM

#

mint garnet Yes

for letter in range(0,len(chosen_word)):

#

like this?

mint garnet Jul 4, 2024, 1:22 PM

#

Looks good 👍

rose aspen Jul 4, 2024, 1:22 PM

#

ok

#

think i got an idea

mint garnet Jul 4, 2024, 1:23 PM

#

for letter in range(len(chosen_word)):```
This would be also valid, since 0 is implied by range if you don't specify a start value

rose aspen Jul 4, 2024, 1:23 PM

#

do i need to convert my chosen_word into a list with all its characters?

mint garnet Jul 4, 2024, 1:23 PM

#

But your's is also valid

#

No you can index a string directly, just like you would a list

rose aspen Jul 4, 2024, 1:23 PM

#

oh

#

i never knew

#

amazing

dull oasis Jul 4, 2024, 1:24 PM

a string is kinda a type of an array

character array

!e

string = "test"
print(string[2])```
