The most Pythonic way to import a module from another folder is to place an empty file named __init__.py into that folder and use the relative path with the dot notation. For example, a module in the parent folder would be imported with from .. import module. The __init__.py file signals to Python that the … Read more

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
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
