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

In a document using Python, I did however the file get all together type like this:

AMANDAJULIANAVANESSAPATRICIA

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()

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

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

Or use only the write function by adding line breaks with join :

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

Official documentation of writelines :

writelines (lines) : 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.
