How to specify values in JSON key

Question

I have a JSON and I want to access the keys in "rates". This is the aforementioned JSON:

currency = '''
{
  "rates": {
    "CNY": 7.6588,
    "BGN": 1.9558,
    "USD": 1.114
  },
  "base": "EUR",
  "date": "2019-07-24"
}
'''

qwe = json.loads(currency)

When i try

for x in qwe['rates']:
    print(x)

I get the values CNY, BGN, USD without the keys.

But also when I try print(qwe['rates']) I get {'CNY': 7.6588, 'BGN': 1.9558, 'USD': 1.114}

My idea is to specify the keys for each value

`I get the values CNY, BGN, USD without the keys.` those ARE the keys. ;) E.g. key is 'CNY', value is '7.6588'. You can do `for key, value in qwe['rates'].items():` to get both key and value at once. — h4z3, Jul 25 '19 at 14:31
"I get the values CNY, BGN, USD without the keys." Um, those *are* the keys. But the difference here is that a dictionary iterator only provides the keys, not key/value pairs. `print` treats `qwe['rates']` as a *string*, not an iterator. — chepner, Jul 25 '19 at 14:31

qwe = json.loads(currency)
for key, value in qwe['rates'].items():
    # do something with 'key' here

To access the value you have to print qwe['rates'][x]

for x in qwe['rates']:
  print(qwe['rates'][x])

Output

7.6588
1.9558
1.114

You should use the .items() dict method:

for key, value in qwe['rates'].items():
    print(key, value)
