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:
ufunc.reduce(a[, axis, dtype, out, keepdims])ufunc.accumulate(array[, axis, dtype, out])ufunc.reduceat(a, indices[, axis, dtype, out])ufunc.outer(A, B)ufunc.at(a, indices[, b])])])
