Today I started learning Python, and I explored some fundamental concepts that helped me understand how Python actually works behind the scenes. What is Python? Python is a high-level, interpreted programming language. Being high-level means it is easy to read and write, as it is closer to human language and abstracts away hardware complexity. This makes it very different from low-level languages like assembly or machine language , which directly interact with hardware. Is Python Really Interpreted? We often hear that Python is an interpreted language, but there is a bit more to it. Python actually works in two main steps: Compilation to Bytecode First, Python converts your code into an intermediate format called bytecode. Execution using Python Virtual Machine (PVM) This bytecode is then executed by the Python Virtual Machine (PVM.) This process is what makes Python both flexible and easy to debug. What is pycache ? While running Python programs, you might notice a folder named pycache .…
