12/10/2023 0 Comments Itertools izip pyton 3![]() In Python, any object that can implement for loop is called iterators. There are various types of iterator in itertools module. Note: If you are using the zip() function and map() function that means you are already using itertools. The Python zip() function calls iter() on each of its argument and then calls next() by combining the result into tuple. ![]() It iterates over tuples and return their corresponding elements. Let's take an example: Python built-in zip() function accepts any number of arguments as iterable. The functions in itertools are used to produce more complex iterators. IntroductionĪccording to the official definition of itertools, " this module implements a number of iterator building blocks inspired by constructs from APL, Haskell, and SML." In simple words, the number of iterators can together create 'iterator algebra' which makes it possible to complete the complex task. In this article, we will describe itertools for beginners are well as for professionals. The key thing about itertools is that the functions of this library are used to make memory-efficient and precise code.īefore learning the Python itertools, you should have knowledge of the Python iterator and generators. Python provides excellent documentation of the itertools but in this tutorial, we will discuss few important and useful functions or iterators of itertools. This library has pretty much coolest functions and nothing wrong to say that it is the gem of the Python programing language. Itertool is one of the most amazing Python 3 standard libraries.
