Return dataframe subset based on a list of boolean values

Question

I\'m trying to slice a dataframe based on list of values, how would I go about this?

Say I have an expression or a list l = [0,1,0,0,1,1,0,0,0,1]

Answer 1

Convert the list to a boolean array and then use boolean indexing:

df = pd.DataFrame(np.random.randint(10, size=(10, 3)))

df[np.array(lst).astype(bool)]
Out: 
   0  1  2
1  8  6  3
4  2  7  3
5  7  2  3
9  1  3  4
