I have a big list of intergers and want to count the number of elements greater than some threshold value. I can use 'for' loop for this task, but is there another approach?


If I have to count how many elements are greater than 5, it should give 10.

You can convert the list to Numpy array and then use Numpy functions to count the elements greater than a particular value. Check the following example.

>>> a=[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]

>>> a=np.array(a)

>>> np.count_nonzero(a>5)


>>> np.count_nonzero(a<=5)
