I can't do anything with python dict?

Im really stuck with a little problem that I have.

diccionario_antiguos = {}
            
    data = open('Currency_price.json')
    for i in data:
        diccionario_antiguos = i

Currency_price.json is a file which contains a dictionary like this:

{"Dolar": ["80,25", "86,25"], "Euro": ["96,59", "97,04"]}

With the key being the currency and the value a list with its prices.

My problem is that after I pass all the info to diccionario_antiguos, I can't manipulate anything inside it.

if i do for instance:

print(diccionario_antiguos.get('Dolar')

I get 'str' object has no attribute 'get'

If I do

print(diccionario_antiguos['Dolar']

I get string indices must be integers

And then I said "Oh, I should have tu use integers", so I did:

print(diccionario_antiguos[0])

No Exception there, but I get [] (when I printed the whole dictionary and I KNOW the data IS there).

I don't know what's happening, because if I apply this methods with any dictionary, they'll work, even if the key is a String.

Any solutions? Thank you!
