How to get 1st Buy (bid) and 1st (sell) ask price from depth

Hi Sir,

I am doing below code. Till "buy" I am getting it. But I want to retrieve 1st buy and 1st sell price from depth

Code -

symbol='NFO:ICICIBANK21DECFUT'
f2=quoteMethod1(symbol)

#print(f2)

current=f2['NFO:ICICIBANK21DECFUT']['depth']['buy']
print (current)




output -

[{'price': 731.05, 'quantity': 1375, 'orders': 1}, {'price': 731, 'quantity': 5500, 'orders': 4}, {'price': 730.95, 'quantity': 1375, 'orders': 1}, {'price': 730.9, 'quantity': 1375, 'orders': 1}, {'price': 730.85, 'quantity': 2750, 'orders': 2}]



Now how can I get 1st price like "731.05" ?????
