Isn't there a sumif, countif function like Excel in the Numpy array?

If you use boolean array indexing to specify subscripts using a conditional expression,

# numpy array for testing
arr = numpy.array(list(range(10))))
# output sumif
print(arr[arr>5].sum())
# Output countif
print(numpy.sum(arr>5))

You can write as shown in
