Why do i get an error? (Access the Dictionary data-type by way of its native index)

Question

dictionary = {
"fimble" :4,
"Jack" : 13,
"umbrella": 10,
"bottles": 2,
"pn": "Tgursday 11May17",
3:464
}

print(dictionary[3])

# You can still access the dictionary by it's native index
print(dictionary[dictionary[3]])

Answer 1

print(dictionary [dictionary [3]])
print(dictionary[464]) #Value of key 3 is 464
error #Coz there is no such key 464

Answer 2

Dictionary are not like lists. You can not access it values using index, but using keys.

Answer 3

The first print works because there is a key that is 3 in the dictionary.
