Universal function methods

How can functions have methods? As we said earlier, universal functions are not functions but Python objects representing functions. Universal functions have five important methods listed as follows:

1. ufunc.reduce(a[, axis, dtype, out, keepdims])
2. ufunc.accumulate(array[, axis, dtype, out])
3. ufunc.reduceat(a, indices[, axis, dtype, out])
4. ufunc.outer(A, B)
5. ufunc.at(a, indices[, b])])])
