The NetworkX Package is a Python library for studying graphs and networks. It provides tools for the creation, manipulation, and study of dynamic and complex network structures. With NetworkX, we can load and store networks in many data formats, generate many types of random and classic networks, analyze network structure, build network models, design new
Let’s talk about synchronization in Python. Multithreading allows your computer to perform actions in parallel, utilizing multiple cores/ multiple CPUs present on your system. However, when it comes to reading and updating shared variables at the same time, it can lead to erroneous results. We will learn how to synchronize threads to give correct results.
