Python in a Nutshell

Name

reduce

Synopsis

                        u.reduce(a,axis=0)

Returns an array r with the same type code as a and rank one less than a’s rank. Each element of r is the reduction of the elements of a, along the given axis, with the function or operator underlying u. The functionality of u .reduce is therefore close to that of Python’s built-in reduce function, covered in Chapter 8. For example, since 0+1+2+...+9 is 45, add.reduce(range(10)) is 45. This is just like, when using built-in reduce and import operator, reduce(operator.add,range(10)) is also 45.
