I have a list and I wanted to write in another file

["AMANDA,"JULIANA","VANESSA","PATRICIA"]

In a document using Python, I managed however the file gets all together like this:

AMANDAJULIANAVANESSAPATRICIA

how could I fix this?

def ordem_txt(palavras):  
       arq = open(palavras, 'r')  
       texto = arq.read()  
       palavras = texto.replace("\n", " ").split(" ")  
       palavras.sort(reverse=False)  
       #print(palavras)  
       return palavras  

def write_txt(palavras, caminho):  
    arq = open(caminho, "w")  
    arq.writelines(palavras)  
    arq.close()
python python-3.x

  • Put your code in the question, please.

  • arq.writelines() does not add line separators, you have to add them to the list items yourself.

As commented, the function writelines does not add any separator between the values of the list, so if the intention would be to write a word per line, you need to manually add the character \n. For example:

arq.writelines(palavra + '\n' for palavra in palavras)

Or just use the function write adding line breaks with the join:

arq.write('\n'.join(palavras))

Official documentation of writelines:

writelines(): Write a list of Lines to the stream. Line separators are not Added, so it is usual for each of the Lines provided to have a line separator at the end.
