Hangman Game in Python-3

Welcome to Code Review!

PEP-8

Since you're still new to python, it's a good idea to keep a window/tab open with PEP-8 loaded into it. It is mostly suggestions for coding style. Few things that can be picked up from the same:

• Comparisons to singletons like None should always be done with is or is not, never the equality operators.
• Comments should be complete sentences. The first word should be capitalized, unless it is an identifier that begins with a lower case letter (never alter the case of identifiers!).
• PEP 257 describes good docstring conventions. Note that most importantly, the """ that ends a multiline docstring should be on a line by itself:

Functions

As you've already raised this point, splitting the code into individual functions is always a good practice.

if __name__ block

Put the execution logic of your script inside the if __name__ == "__main__" block. Read more about the details on why on stack overflow.

f-string

Python 3.x also introduced literal string interpolation, or more commonly used term: f-string. Read more about it here (PEP-498).

Type hinting

When writing functions, you can also make use of type hinting to provide a more readable flow of your code to anyone. This helps removing the manual labour of having to backtrack variable types etc. More details can be found in PEP-484.

Game logic

The initialisation of presentation array can be simplified to:

presentation = ["_"] * len(answer)

For every guessed character from the user, you keep looping over the answer_list, irrespective of validating whether the guess is correct or not.

Before the loop over each character of the correct word, you have setup ind = 0 which is never really used.

Your global while loop relies on the condition completion == False (which should ideally be completion is False) but you break out before the loop/condition really has a chance to do so for you, making the variable useless.

Rewrite

from typing import List

MAX_ATTEMPTS: int = 5


def get_answer() -> str:
    return input("What's the word? ")


def correct_guess(char_count: int, guessed_word: List[str]):
    print(f"Your guess is correct, there was/were {char_count} matches in the word.")
    print(" ".join(guessed_word))


def game_win(guessed_word: List[str]) -> bool:
    return "_" in guessed_word


def game():
    answer = get_answer()
    correct_letters = set(answer)
    guessed_word = ["_"] * len(answer)
    incorrect = 0
    while True:
        if incorrect >= MAX_ATTEMPTS:
            print("You lost!")
            break
        attempt = input("Guess: ")
        if attempt not in correct_letters:
            incorrect += 1
            continue
        char_count = 0
        for index, char in enumerate(answer):
            if char == attempt:
                guessed_word[index] = char
                char_count += 1
        correct_guess(char_count, guessed_word)
        if game_win(guessed_word):
            print("Congrats, you got everything correct")
            break


if __name__ == "__main__":
    game()
