The . append() is not working in my dictionary - Python

Question

Hello, my problem is this: I have a dictionary called People: pessoas = {} that allows me to register the name and age of the person. I made a input asking how many people the user would like to register: quantidade = int(input("Quantas pessoas serão cadastradas? ")).
After that he executes a for: for a in range(0, quantidade):.
So far so good... I ask the name and age of the person to after that I make a .append() in my dictionary and it returns me the following error:

AttributeError: 'dict' object has no attribute 'append'

I really don’t understand why the mistake. Can anyone explain?
The complete code:

pessoas = {}

quantidade = int(input("Quantas pessoas serão cadastradas? "))

for a in range(0, quantidade):
    nome = input(f"Digite o nome da pessoa {a + 1}: ")
    idade = input(f"Digite a idade de {nome}: ")
    pessoas.append(nome)
    pessoas.append(idade)

Python dictionaries do not have .append: they always keep a key and a value, and this is independent of the insertion order - Given the key (in this case, the "name"), it will always take the same time to return the corresponding value ("age"):

pessoas = {}

quantidade = int(input("Quantas pessoas serão cadastradas? "))

for a in range(0, quantidade):
    nome = input(f"Digite o nome da pessoa {a + 1}: ")
    idade = input(f"Digite a idade de {nome}: ")
    pessoas[nome] = idade

print(pessoas)

To learn, it’s important to do it this way. When creating more complex programs it is important that a data that can be repeated (the name), is not the key of the dictionary: the values that comes last go over-write the first ones - but this you take with time - for example, in this case it may be better to have a "list of dictionaries", in which each dictionary has the key "name" and "age" separated. But to get there, you need to understand dictionaries first.
