Problem comparing strings and string being broken in two python rows

I was creating a game that scrambles words, and the user has 6 attempts to guess what the word is. I'll put the code here:

import random

def main():
    while True:
        input('Presisone enter para sortear uma nova palavra.')
        palavra_oculta, dica = EscolhePalavra()
        palavra_embaralhada = EmbaralhaPalavra(palavra_oculta)
        palavra_embaralhada = palavra_embaralhada.lower()
        palavra_oculta = palavra_oculta.lower()
        tentativas = 6
        while tentativas != 0:
            print('\nA palavra embaralhada é: %s'%palavra_embaralhada)
            print('A dica é: %s'%dica)
            print('Você ainda tem %d tentativas.'%tentativas)
            palpite = input('Digite seu palpite: ')
            if palpite == palavra_oculta:
                print('Parabéns, você acertou!!!')
                break
            else:
                print('Ainda nao, tente novamente!')
                tentativas -= 1
        if tentativas == 0:
            print('Você perdeu! a palavra correta era %s.'%palavra_oculta)
        else:
            print('Parabéns, você acertou a palavra!!!')

def EscolhePalavra(): #Essa função está funcionando normalmente, a usei em outro jogo.
    lista_arquivos = {'Animais.txt' : 'Animal', 'Frutas.txt' : 'Fruta',
                      'Objetos.txt' : 'Objeto', 'Pessoas.txt' : 'Pesssoa',
                      'Profissões.txt' : 'Profissão'}
    arquivo_escolhido = random.choice(list(lista_arquivos.keys()))
    palavra = random.choice(open(arquivo_escolhido).readlines())
    dica = lista_arquivos[arquivo_escolhido]
    return(palavra, dica)

def EmbaralhaPalavra(palavra):
    palavra = list(palavra)
    random.shuffle(palavra)
    palavra = ''.join(palavra)
    return palavra

if __name__ == '__main__':
    main()

Let's face the problems: First, with the word scrambled. For some reason I still do not know which one, by giving print to palavra_embaralhada , most of the time it gets broken into two lines. I have already tried to give a print on a separate line in the code, but the problem persists.

The second is that the comparison between the string written by the user stored in the variable palpite , and the palavra_oculta almost always goes wrong. I was only able to hit once. As much as I type the correct word, the program considers it to be two different strings . What I have to do?

First, with the word scrambled. For some reason that has not yet I know which, when giving a print in word_embarse, most of the times it gets broken in two lines. I've already tried to print it on a line in the code, but the problem persists.

The problem occurs in the EmbaralhaPalavra function, assuming that the palavra_oculta variable has the Bar value, when using list , the value returned is a list containing ['B', 'a', 'r', '\n'] , and when doing the random.shuffle , the following happens (may vary) : ['a', 'B', '\n', 'r'] , ie the reason for line break , is due to new line a> that is created using list . To correct this, you will need to remove the new line before doing the shuffle. One way to do this is to use the rstrip method, there are also other ways.
```
def EmbaralhaPalavra(palavra):
   palavra = palavra.rstrip()
   palavra = list(palavra)
   random.shuffle(palavra)
   palavra = ''.join(palavra)
   return palavra
```

The second is that the comparison between the string written by the user stored in the guess variable, and the search_word almost always exits wrong. I only managed to hit it once. As much as I type the word, the program considers it to be two strings many different. What do I have to do?

Same problem . Now in the EscolhePalavra function, in the line where you open the file and read the lines:
```
palavra = random.choice(open(arquivo_escolhido).readlines())
```
readlines() returns everything, including new lines, when comparing: if palpite == palavra_oculta.. , is compared: Bar with Bar\n . To resolve this, you can use the same solution that was used in the first problem, or use the str.splitlines() instead of readlines() , this will eliminate line breaks .
```
def EscolhePalavra(): 
   lista_arquivos = {'Animais.txt' : 'Animal', 
                     'Frutas.txt' : 'Fruta',
                     'Objetos.txt' : 'Objeto', 
                     'Pessoas.txt' : 'Pesssoa',
                     'Profissões.txt' : 'Profissão'}
   arquivo_escolhido = random.choice(list(lista_arquivos.keys()))
   linhas = open(arquivo_escolhido).read().splitlines()
   palavra = random.choice(linhas)
   dica = lista_arquivos[arquivo_escolhido]
   return(palavra, dica)
```
The comparison of strings in Python is case-sensitive , which can affect the result of the game, of the variable palavra_oculta with the value of the variable palpite , which may contain uppercase letters, also use the lower() method in palpite .
