Chapter 01 Not defined error

[bhatz829-zz]

df = df_all_dates.join(df[['adj_close']], how='left')
.fillna(method='ffill')
.asfreq('M')

This is the line with the error. It says df is not defined.

Hi! You also need to run the code from the How to do it... section, it will execute without errors then :)
