- Importare file csv

Scusate sono alle primissime armi.
Sto leggendo un libro sul trading on line che spiega come utilizzare python per creare trading system.
Per prima cosa si dovrebbero importare i dati di uno strumento finanziario salvati su un file csv.
Ho provato a farlo ma mi indica l'errore che riporto qui sotto.
Potreste darmi una mano?
grazie
