- Note the differences between the following ways of adding to a list:
as_letters = ['hello'] as_letters += 'there'
- creates
['hello', 't', 'h', 'e', 'r', 'e']
- while
as_word = ['hello'] as_word += ['there']
- creates
['hello', 'there']
np.where(BOOLEAN)returns a tuple; to get to the actual indices, you neednp.where(BOOLEAN)[0]. If you specifically only want the first place something is try in the BOOLEAN, use you neednp.where(BOOLEAN)[0][0].
