[Python] Why do I receive - AttributeError: 'str' object has no attribute 'items' [closed]

My Code:

def API_Gather():

# Build list of Owned Stock Symbols
self.ticker_List = []

# Open the data file to find individual symbols owned (self.filePath4)
with open(self.filePath4, "r") as f:
self.data = json.load(f)
f.close()

# Parse data to gather Owned Ticker Symbols
for x in self.data:
data_symbol = x["Symbol"]
if data_symbol not in self.ticker_List: self.ticker_List.append(data_symbol)
else:
next
next
my_url = self.API_url
my_headers = self.API_headers

for ticker in self.ticker_List:
my_querystring = {"symbols":ticker}
# Create the API response
response = requests.request("GET", url=my_url, headers=my_headers, params=my_querystring)

# Create the API Data in json format
data = json.loads(response.content)

# Bypass header detail
results = data['quoteResponse']['result']
self.Symbol = results[0]["symbol"]
self.Name = results[0]["displayName"]

Note: my_url and my_headers are exact. If run in test code work fine:
