How to run a number of functions by parsing a list in python?

I have a class that returns a pandas.DataFrame with a number of columns. I'd like to plot these columns individually. One way to do it is by 

lst=[result.df.open, result.df.close] 
for i in lst: i.plot()

however I'd like to do something like 

lst=['open', 'close']
for i in lst: result.df.i.plot()

but this doesn't work because I'm parsing strings. I'm wondering if there's a way to do this? maybe through the use of {} curly brackets but I'm not sure?

In addition to the other answers. If you want to dynamically perform “df.i” when i is a string, you should use getattr(df, i)

foo.bar is equivalent to getattr(foo, ‘bar’)

Supposing df is the pandas dataframe and lst is the list of string corresponding to the columns you would like to plot:

lst=['open', 'close']
for i in lst: 
    df[i].plot()
