I have a list of dictionaries like the following and I want to get for a list the ages of the animals of each owner, for example, the animals of ana have on average x years ... However I am not getting the ages of the animals related to their owners, someone can give a help ?

lista1 =[
{'Idade': '8','Especie': 'Gato', 'Nome do Animal': 'Felix'},
{'Idade': '57','Especie': 'Tartaruga','Nome do Animal': 'Michelangelo'},
{'Idade': '12','Especie': 'Cao', 'Nome do Animal': 'Rantanplian'},
{'Idade': '2','Especie': 'Peixe', 'Nome do Animal': 'Nemo'},
{'Idade': '45','Especie': 'Tartaruga','Nome do Animal': 'Leonardo'},
{'Idade': '9','Especie': 'Cao', 'Nome do Animal': 'Milo'},
{'Idade': '57','Especie': 'Tartaruga','Nome do Animal': 'Raphael'},
{'Idade': '4','Especie': 'Peixe', 'Nome do Animal': 'Dory'}]

lista2 =[
{'Nome do Dono ': 'Ana','Nome do Animal': 'Michelangelo'},
{'Nome do Dono ': 'Eva','Nome do Animal': 'Dory'},
{'Nome do Dono ': 'Ada','Nome do Animal': 'Rantanplan'},
{'Nome do Dono ': 'Ana','Nome do Animal': 'Leonardo'},
{'Nome do Dono ': 'Eva','Nome do Animal': 'Felix'},
{'Nome do Dono ': 'Ana','Nome do Animal': 'Raphael'},
{'Nome do Dono ': 'Eva','Nome do Animal': 'Nemo'}]`

The problem is that I can’t use input’s or anything like that and the code has to work for some list that I put on top of it is just an example. What I have to get ( in this example) is :

[{'Ana':'53','Eva':'5','Ada':'12'}]

But first I need to put the ages of each owner’s animals on a list and then average that’s what I’m not getting. And as far as space is concerned, thank you.

In Lista2 the first courses Nome do Dono has space, this can disturb the time of consultation.

Try using this code snippet

item = int(input("Numero da pessoa: "))

animal = lista2[item-1]['Nome do Animal']

for x in range(len(lista1)):
    if animal in lista1[x]['Nome do Animal']:
        print "Idade:", lista1[x]['Idade']
        print "Especie:", lista1[x]['Especie']
        print "Nome:", lista1[x]['Nome do Animal']
        print "Dono:", lista2[item]['Nome do Dono']
