Python uses the bytecode version if any. Otherwise, it parses the module's .py file, saves it into a .pyc file, and uses the bytecode it just created. Byte code files are also one way of shipping Python codes. Python will still run a program if all it can find are.pyc files, even if the original .py source files are not there.
Apr 23, 2018 · Python is often described as an interpreted language—one in which your source code is translated into native CPU instructions as the program runs—but this is only partially correct. Python, like many interpreted languages, actually compiles source code to a set of instructions for a virtual machine, and the Python interpreter is an implementation of that virtual machine.
May 10, 2020 · Python Global Interpreter Lock (GIL) is a type of process lock which is used by python whenever it deals with processes. Generally, Python only uses only one thread to execute the set of written statements. This means that in python only one thread will be executed at a time. The performance of the single-threaded process and the multi-threaded pro
Mar 5, 2020 · The bytecode can be thought of as a series of instructions or a low-level program for the Python interpreter. After version 3.6, Python uses 2 bytes for each instruction. One byte is for the code of that instruction which is called an opcode, and one byte is reserved for its argument which is called the oparg.

Jun 6, 2024 · Python bytecode is like a secret language that Python uses behind the scenes. When you write your Python code, it doesn’t run directly. Instead, Python translates your code into bytecode, a set of instructions that the Python interpreter can understand and execute. You may be asking why beginners should care about bytecode.
This byte code can be interpreted (official CPython), or JIT compiled (PyPy). Python source code (.py) can be compiled to different byte code also like IronPython (.Net) or Jython (JVM). There are multiple implementations of Python language. The official one is a byte code interpreted one. There are byte code JIT compiled implementations too.

May 22, 2024 · Here's a simplified view of the process: Source Code (.py): The original Python script. Bytecode (.pyc): Compiled version of the script, optimised for execution. Python Virtual Machine (PVM): Executes the bytecode. This process ensures that Python code is portable and can be executed efficiently on any platform.
