How to open a txt file and use to print what I want

Question

I made the following code:

def caixaAlta(texto):
    return texto.upper()

def ultimosNomes(nomeInteiro):
    lista = nomeInteiro.split(' ')
    if lista[-1].lower() == 'junior' or lista[-1].lower()=='sobrinho' \
       or lista[-1].lower()=='neto' or lista[-1].lower()=='filho':
        return caixaAlta(lista[-2])+" "+caixaAlta(lista[-1])
    else:
        return caixaAlta(lista[-1])

def primeirosNomes(nomeInteiro):
    lista = nomeInteiro.split(' ')
    nome=''
    if lista[-1].lower() == 'junior' or lista[-1].lower()=='sobrinho' \
     or lista[-1].lower()=='neto' or lista[-1].lower()=='filho':
        for i in range(len(lista)-2):
            nome = nome + inicial(lista[i])
    else:
        for i in range(len(lista)-1):
            nome = nome + inicial(lista[i])
    return nome

def inicial(nome):
    for i in nome:
        if nome=='da' or nome=='do' or nome=='de' \
           or nome=='das' or nome=='dos' or nome=='e':
            nome=nome.replace(i,".d")
            return nome.lower()+' '

        else:
            return nome[0].upper()

def referencia(nomeInteiro):
    return ultimosNomes(nomeInteiro)+','+primeirosNomes(nomeInteiro)


print(referencia(input('Digite nome do autor: ')))

His exit will be the following:

> Digite nome do autor: Joao Joca da Silva  <- o nome eu digito
> SILVA,JJ.da <- isso que imprime

This way I did I create names and it prints the way I want, but how do I use only names of a txt file and it print the same way?

Answer 1

Try So:

Create a file called.txt file with the names you want, so do it:

import  codecs
wordList = codecs.open('Arquivo.txt' , 'r').readlines()
for w in wordlist:
    print(referencia(w[:-1]))

Pythonism:

Practically all languages have conventions and python is no different, it would be interesting if you read python encoding style guide, to quote an example, rather than using camelcase (minhaVariavel), use snakecase (minha_variavel)

In python you don’t need that lot of ifs to see if something is on a list, in the first sequence of ifs of your code, instead of doing:

if lista[-1].lower() == 'junior' or lista[-1].lower()=='sobrinho' \
   or lista[-1].lower()=='neto' or lista[-1].lower()=='filho':
    return caixaAlta(lista[-2])+" "+caixaAlta(lista[-1])
else:
    return caixaAlta(lista[-1])

You can do

if lista[-1].lower() in ['junior', 'sobrinho', 'neto', 'filho']

Note that you can also read this list of a text file, in the same way that was done to read the input file of the names.

Observing.
This is just a way to read a python txt file, I chose randomly (pq had already answered something with codecs) but there are other ways to do this.
