Jul 28, 2017 · The byte-code (.pyc or .pyo files) are just a binary version of your code line by line, and is interpreted at run-time. But if you use pypy, yes! It has a JIT Compiler and it runs your byte-codeas like Java dn .NET (CLR).

Aug 10, 2023 · PVM converts the Python byte code into machine-executable code and in this interpreter reads and executes the given file line by line. If an error occurs during this interpretation then the conversion is halted with an error message.

Python does create .pyc files (so-called byecode) whenever a library is imported. AFAIK the bytecode can only speed up load times, not execution times. @aitchnyu: Caching the bytecode in .pyc files only speeds up loading indeed, but only becase the Python code is compiled to bytecode before execution anyway.

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 6, 2023 · In summary, Python converts the source code to bytecode using the interpreter and then executes the bytecode using the Python Virtual Machine, which translates it into machine code...

Oct 14, 2020 · If you say that the Python VM "translates a bytecode instruction into the equivalent machine code instruction", or that the VM's 'output' is machine code, then that can lead to confusion such as in the original question.

Python source code is converted to python byte code, which is then executed by the python virtual machine. The .pyc files contain python byte code. Python source code goes through the following process: Lexical analysis. Break the code up into tokens. (See flex in UNIX, nee, lex) Parsing. Generate a syntactic parse tree.

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 2, 2025 · Understanding Python bytecode is essential for optimizing performance, debugging, and grasping Python’s execution model. This article explores the Python execution process, how bytecode works,...

Jun 8, 2023 · Python code is executed using bytecode, which acts as a bridge between machine execution and source code that can be viewed by humans. Understanding bytecode may help with performance analysis,...
