Multi-threading in Python: Basics

Multi-threading in Python is often used when there are tasks related to I/O bound. But before going further, let’s take a few examples where multi-threading could be used: Downloading images from the web and doing image processing-related tasks. It takes some time to download the image and some time to process it too but these […]
