JSON Manipulation Python

import json

x= {
      "BTC" : {
        "price": 5000
      },
      "ETH" : {
        "price": 1000
      }
    }

# convert into JSON:
y = json.dumps(x)
# create a simple JSON array


# change the JSON string into a JSON object
json_object = json.loads(y)

# print the keys and values
for key in json_object:
    value = json_object[key]
    print("The key and value are ({}) = ({})".format(key, value))

btc_obj = json_object['BTC']
print(btc_obj["price"])
print(type(obj))
print(obj.items())
#print(json_object['ETH]["price"])
