Chrome log: Nested dictionary in python

Question

I’m figuring out how to access to this nested dictionary(it’s a log from chrome)

How Do I access to these keys or at least the ‘method’ and ‘params’ ?
I tried message[method] to get ‘Network.responseReceived’ value but it return an error

def new_file_log(self):
# Chrome log
logs = self.driver.get_log("performance")
    for log in logs:
        message = log["message"]
        if 'Network.responseReceived' in message:
            print(f"{message}")
            # print(f"message['method']")

Error:
print(f"{message[‘method’]}")

TypeError: string indices must be integers

The ‘{message}’ value is what I attached below:

{'message': {'method': 'Network.responseReceived', 'params': {
'frameId': '7592BBC26C81063AFE730881A0DCC64A',

EDIT 1 :
Every String starts with:

[{'level': 'INFO', 'message': '{"message": {'method': ....
logs = json.loads(self.driver.get_log("performance")) # TypeError: the JSON object must be str, bytes or bytearray, not list

or

print(f"{log['message'].keys()}") # AttributeError: 'str' object has no attribute 'keys'

print(f"{log.keys()}") #  dict_keys(['level', 'message', 'timestamp'])

EDIT 2:
I’ve found this solution. I don’t know if it’s the best

    def new_file_log(self):
    logs = self.driver.get_log("performance")

    for log in logs:
        message = json.loads(log["message"])["message"]
        if "Network.responseReceived" == message["method"]:
            print(f"{message['method']}")
            print(f"{message['params']}")
            print(f"{message['params']['response']['url']}")

            print(' ')

Answer 1

This is in json format (very similar syntax to python data types), you should try:

logs = json.loads(self.driver.get_log("performance"))

Answer 2

Just Reproduce your code here. Can you try something like this.?

with open('stack.json') as stack:
    st =  json.load(stack)
    out=  st.get('message')['method']
    if 'Network.responseReceived' in out:
        print(f"{message}")

Just using dummy json to give you a hint
Stack.json

{
    "message": {
        "method": "Network.responseReceived",
        "params": {
        }
}

}
