Python Itertools Module

Python Itertools Module Comparison & Implementation (Accumulate Function)

A collection data type is always being used in the programming field. So as Python programming language. There are several collection data types in Python such as list, tuple, set, dictionary, numpy array, etc. It is very often that we will do an operation in a collection of data. Like taking the sum or average from a collection of numbers, taking certain numbers with specific criteria (odd/even number case), or even iterating for each item in it.

Usually, people tend to use standard looping statements to access or manipulate data collection.

It is common for a beginner programmer (or even a professional) to use this kind of programming paradigm. But, there are other ways to do this in a simpler and faster way. We just have to import a library called Itertools. So, what do these itertools do? How it can improve our code performance? Please take a look at this short article!
