how to get lot size of stocks with original stock name, instead of some other symbol...

for example- It is returing "banknifty" with its lot size.. but the original stock symbol is "NIFTY BANK"
is their any way to filter this out?

@kishoretarun As of now this code won't support that feature. You can try this code to find "NIFTY BANK".

If you want stock name in nsetool library change these lines in get_fno_lot_sizes method.

(underlying_code, _,  name) = [x.strip() for x in line.split(',')[0:3]]
res_dict[underlying_code] = int(name)

Save this in stock.py file and run python stock.py.
