Import zip_longest() function from itertools module using the import keyword.Method #1: Using Built-in Functions (Static Input) Using Built-in Functions (Static Input).It alternately prints the values of lists in sequence. Given second List = Įxplanation: Here it takes 25 from the first list and 100 from the second list, similarly If the iterables are of various lengths, use this value to pad the outputs. These are the iterables like list, string, and so on.įillvalue: This is Optional. Syntax: zip_longest( iterable1, iterable2, fillvalue) Note: If no fillvalue is given it prints 'None' to fill in the gaps. If one of the iterables is completely printed, the values supplied to the fillvalue argument are used to fill in the gaps. It alternately prints the values of iterables in sequence. This iterator is classified as a terminating iterator.
This module provides the following types of iterators: Iterators are classified into three types. itertools enable us to solve complex problems quickly and easily. Itertools in Python refers to a Python module that allows the creation of iterators, which aids in efficient looping, as well as time and space efficiency. They make it very simple to iterate through iterables such as lists and strings.

millions of records), zip(a, b) will build a third list with double space.īut if you have small lists, maybe zip is faster.Itertools is a Python module that contains a collection of functions for dealing with iterators. Moreover, if lst_a and lst_b are very large (e.g. Using zip would have computed all (a, b) couples before entering the cycle. #At each cycle, the next couple is provided
#Itertools izip to list code#
the following code may exit after few cycles, so there is no need to compute all items of combined list: lst_a =. So, if you need a list (an not a list-like object), just use 'zip'.Īpart from this, 'izip' can be useful for saving memory or cycles.Į.g. TypeError: 'itertools.izip' object is unsubscriptable One important difference is that 'zip' returns an actual list, 'izip' returns an 'izip object', which is not a list and does not support list-specific features (such as indexing): > l1 = Zip computes all the list at once, izip computes the elements only when requested.
