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).

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...

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.

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.

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.

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.

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.

Feb 18, 2025 · Unlike purely interpreted languages, Python compiles source code into bytecode, which is then executed by the Python Virtual Machine (PVM). Understanding this execution model helps developers optimize performance, debug effectively, and …

Bytecode is the low-level representation of the python code which is the platform-independent, but the code is not the binary code and so it cannot run directly on the targeted machine. It is a set of instructions for the virtual machine which is also called as the Python Virtual Machine [PVM].
