Looping Through The Tickers in Our List of Stocks doesn't work

[mpquochung]

I got this error when running the code:

I have tried several things but doesn't work. Anyone help me pls!
P/S: this loop can only create 134 tickers, does this mean something happened with the 135th?

The sample code isn't ideal as the response to the batch request may have symbols missing. I think it's better to loop over the symbols in the response rather than the symbols in the request. Something like...

stocks = pd.read_csv('sp_500_stocks.csv')
all_symbols = stocks['Ticker']
step = 100

my_columns = [... whatever]
df = pd.DataFrame(columns=my_columns)

for i in range(0, len(all_symbols), step):
    symbols = all_symbols[i:i + step]
    symbols_text = ','.join(symbols)

    url = f'{base_url}/stable/whatever...'
    response = session.get(url)
    data = response.json()
    for symbol in data:
        quote = data[symbol]['quote']
        ... etc

(also note, the above code has a greatly simplified 'chunking' mechanism and achieves everything in a single loop)
