Help python by taking only the last data from the list

Question

I have a website and I need a name separation system:last name with list, the data is in a txt and I normally import the data is for example: maria:Carla Joao:lima wanted to be able to separate as follows when this print in data it would leave in different lists since the data are each in a line ['maria','Carla'] and ['Joao,'file'], and also separate as follows by variables, name = names[0]when giving a print in name would show ['Joao'] ['maria'],the first part of the code at the time ta so, it is only separating the first name:surname from the list also would like to solve this:

    arquivo=raw_input("Digite o nome do arquivo para separar: ")
    ler=open(arquivo)
    with ler as f:
     for line in f:
       nome, sobrenome = line.split(":")

Answer 1

You can create an object with the attributes name and surname

class Objeto(object):
    def __init__(self):
        self.nome = ''
        self.sobrenome = ''

after this you will need to work with arrays, the idea is for each row within your foreach mount a new object with the filled attributes and add them to this array, with some changes your code would look like this:

arquivo=raw_input("Digite o nome do arquivo para separar: ")
    ler=open(arquivo)
    nomes = []
    with ler as f:
        for line in f:
            obj = Objeto()
            obj.nome, obj.sobrenome = line.split(":")
            nomes.append(obj)

Now you have all the names within your array nomes

To access the items you can test:

for item in nomes:
    print('nome: ' + item.nome + ' , Sobrenome: ' + item.sobrenome)

You can convert this list to json, for this you will need to create the following method (Object for Dict):

def para_dict(obj):
    if hasattr(obj, '__dict__'):
        obj = obj.__dict__
    if isinstance(obj, dict):
        return { k:para_dict(v) for k,v in obj.items() }
    elif isinstance(obj, list) or isinstance(obj, tuple):
        return [para_dict(e) for e in obj]
    else:
        return obj

Now it is possible to make the conversion to json

import json
jsonstr = json.dumps(para_dict(nomes))
