import: use & instead of and

Simply, use np.where(condition1 & condition2) will get the right answer, but `np.where( list(condition1) and list(condition2)) won't return the right answer.

So, please use &.

Further disscus

Try this python script:

a = [True, False, False]
b = [False, True, True]
print('a and b', a and b)

You will get:

a anb [False, True, True]
