Check if pandas column contains all elements from a list

Question

I have a df like this:

frame = pd.DataFrame({\'a\' : [\'a,b,c\', \'a,c,f\', \'b,d,f\',\'a,z,c\']})

And a list of items:

let         


        

Answer 1

frame.iloc[[x for x in range(len(frame)) if set(letters).issubset(frame.iloc[x,0])]]

output:

        a
 0  a,b,c
 1  a,c,f
 3  a,z,c

timeit

%%timeit
#hermes
frame.iloc[[x for x in range(len(frame)) if set(letters).issubset(frame.iloc[x,0])]]

output

300 µs ± 32.9 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
