  • Importare file csv
    Forum >> Principianti
    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







    import pandas as pd

    import numpy as np

    import matplotlib.pyplot as plt





    data = pd.read_csv("NSQ_dati.csv")
