What is a pandas series analogous to? In python, we have seen the use of square brackets ( []) in different context: To take a slice of a string (e.g. myString[:5] returns the first 5 characters of myString) To access a portion of a numpy array (e.g. img[2:3,:] returns the third row of img -- a 2-dimensioanl array)
