Python Tutorial – Filter and Reduce Function



In this Python Programming video tutorial you will learn about filter and reduce function in detail.

we can see the advantage of the lambda function when it is used with the some built in functions like map reduce filter.

filter function will filter the element of the iterables based on some function.
syntax is filter(function,iterable)
this is an inbuilt function so it is faster.

reduce function will reduce a iterable to single element using some functions, this function can be used when we want to do some computation on list or tuple.
syntax is reduce(function,iterable)

In python 3 reduce function is defined in functools module, so to use reduce function we need to import that module.
