We know what a blockchain is and its wide applications. Blockchain is a distributed computing technology involving multiple nodes distributed across geographies. The problem is to ensure that each node gets the exact copy of the data. Hence, some protocol is needed to achieve this unison or consensus. This post tries to cover the need … Read more
To customize the behavior of the non-equality operator x != y, override the __ne__() dunder method in your class definition. Python internally calls x.__ne__(y) to compare two objects using x != y. If the __ne__() method is not defined, Python will use the is not operator per default that checks for two arbitrary objects whether … Read more
This article is the first of several articles discussing functions from the math module from the Python Standard Library. The articles are organized thematically; functions that are closely related to each other are discussed in the same article. In this article, we discuss four functions: math.floor, math.ceil, math.trunc, and math.modf. They are all related to … Read more
Introduction In this article, we will look at how you can set an array element with a sequence, and then we will also learn the ways to solve the error – “ValueError: setting an array element with a sequence“. In Python, the ValueError generally gets raised when a function gets the argument of the right … Read more
You can watch the slides as a GIF here: And download the slides as PDF here. What’s the Best-First Search Algorithm? After several articles on uninformed search algorithms, we continue our journey to informed search algorithms. The first one in the series is the Best-First search algorithm. In general, informed search algorithms use some kind … Read more

Mutable Data Types The objects whose values can change after the creation of the objects are known as mutable data types. The values can be changed — you can’t add an item to the object, delete an item from the object, or change any value in the object with another value. Sets are mutable. Lists … Read more
