Compilation is a translation step, and the byte code is a low-level platform-independent representation of source code. Note that the Python byte code is not binary machine code (e.g., instructions for an Intel chip). Actually, Python translate each statement of the source code into byte code instructions by decomposing them into individual steps.
May 10, 2020 · Bytecode is an intermediate language for the Python virtual machine that’s used as a performance optimization. Instead of directly executing the human-readable source code, compact numeric codes, constants, and references are used that represent the result of compiler parsing and semantic analysis.
Apr 23, 2018 · A Python Interpreter Written in Python by Allison Kaptur is a tutorial for building a Python bytecode interpreter in—what else—Python itself, and it implements all the machinery to run Python bytecode. Finally, the CPython interpreter is open source and you can read through it on GitHub.
Aug 10, 2023 · It converts it into something called byte code. So within Python, compilation happens, but it’s just not in a machine language. It is into byte code (.pyc or .pyo) and this byte code can’t be understood by the CPU. So we need an interpreter called the Python virtual machine to execute the byte codes.
Feb 25, 2024 · Bytecode is the under-the-hood representation of your Python code, a middle-ground between the high-level Python you write and the binary machine code executed by the computer’s processor. When you run a Python script, your code is transformed into this low-level, platform-independent format, which the Python Virtual Machine (PVM) then executes.
Jun 8, 2023 · The Python compiler, which is a component of the CPython interpreter, converts your source code into CPython bytecode at this stage. This bytecode is a set of lower-level, cross-platform instructions.
May 2, 2021 · A virtual machine (or bytecode interpreter) works on a linear instruction's flow. A "program" being linear gives us way better performances compared to non-linear one, because we don't have to fetch data 5KiB after the current one, then 2MiB before... the CPU cache will love it, as it will be more predictible.
