Mar 5, 2020 · CPython compiles the python source code into the bytecode, and this bytecode is then executed by the CPython virtual machine. Generating bytecode files. In Python, the bytecode is stored in a .pyc file. In Python 3, the bytecode files are stored in a folder named __pycache__. This folder is automatically created when you try to import another ...

Jul 22, 2024 · Step 1: Parsing. The first step in the compilation process is parsing. When you run a Python script, the interpreter reads the source code and breaks it down into a series of tokens. Tokens are ...
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.
May 10, 2020 · The instruction stream can then refer to a constant with an index into the lookup table. The same is true for variables stored in the co_varnames field. CPython developers gave us another tool called a disassembler to make inspecting the bytecode easier. Python’s bytecode disassembler lives in the dis module that’s part of the standard library.
Jul 7, 2024 · The PVM is the runtime engine of Python. It reads and executes the bytecode instructions, acting as an abstraction layer between the bytecode and the hardware. Loading Bytecode: The PVM loads the ...
