Why is my data from IEX Cloud API Token not going through?

Question

On Jupyter Notebook:

Whenever, I run this code it says N/A for the Number of Shares to Buy section. I followed this tutorial on youtube: https://www.youtube.com/watch?v=xfzGZB4HhEE&t=5656s. Any suggestions on what I should change. I have spent days looking at the code and can't find a solution.

from secrets import IEX_CLOUD_API_TOKEN

symbol='AAPL'
api_url = f'https://sandbox.iexapis.com/stable/stock/{symbol}/quote?token={IEX_CLOUD_API_TOKEN}'
data = requests.get(api_url).json()
data

data['latestPrice']
data['marketCap']

my_columns = ['Ticker', 'Price','Market Capitalization', 'Number Of Shares to Buy']
final_dataframe = pd.DataFrame(columns = my_columns)
final_dataframe

final_dataframe = final_dataframe.append(
                                        pd.Series(['AAPL', 
                                                   data['latestPrice'], 
                                                   data['marketCap'], 
                                                   'N/A'], 
                                                  index = my_columns), 
                                        ignore_index = True)
final_dataframe

final_dataframe = pd.DataFrame(columns = my_columns)
for symbol in stocks['Ticker']:
    api_url = f'https://sandbox.iexapis.com/stable/stock/{symbol}/quote?token={IEX_CLOUD_API_TOKEN}'
    data = requests.get(api_url).json()
    final_dataframe = final_dataframe.append(
                                        pd.Series([symbol, 
                                                   data['latestPrice'], 
                                                   data['marketCap'], 
                                                   'N/A'], 
                                                  index = my_columns), 
                                        ignore_index = True)

final_dataframe

def chunks(lst, n):
    """Yield successive n-sized chunks from lst."""
    for i in range(0, len(lst), n):
        yield lst[i:i + n]

symbol_groups = list(chunks(stocks['Ticker'], 100))
symbol_strings = []
for i in range(0, len(symbol_groups)):
    symbol_strings.append(','.join(symbol_groups[i]))
#     print(symbol_strings[i])
