Hi Emanuele,

I'm getting this error with this piece of code:
"ValueError: num must be 1 <= num <= 25, not 0"

for i, col in enumerate(quantitative_columns):
a = df[col]
print(col, pandas.isnull(a).sum())
plt.subplot(5,5,i)
if col in to_log:
a = np.log(a)
plt.hist(a[pandas.notnull(a)], bins=30, label=col)
plt.legend()
print(len(quantitative_columns))
