- Most of Python's bytecode instructions manipulate the evaluation stack of the current call-stack frame, although there are some instructions that do other things (like jump to specific instructions or manipulate the block stack). To get a feel for this, suppose we have some code that calls a function, like this: my_function(my_variable, 2).

When we execute some source code, Python compiles it into byte code. 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).
Apr 23, 2018 · I'll take you through what Python bytecode is, how Python uses it to execute your code, and how knowing about it can help you. How Python works. 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.
Mar 5, 2020 · So 4 lines of source code are converted into 38 bytes of bytecode or 19 lines of bytecode. In the next section, I will explain the meaning of these instructions and how they will be interpreted by CPython. The module dis has a function named dis() which can disassemble the code object similarly.

May 22, 2024 · Python is an interpreted language, but it also involves a compilation step where your Python code (.py) is compiled into bytecode (.pyc). This bytecode is then executed by the Python Virtual Machine (PVM). What is Bytecode? Bytecode is an intermediate representation of your source code.
Feb 25, 2024 · Understanding Bytecode is like having a backstage pass to a Python performance. It offers insights into: Efficiency: By examining Bytecode, you can pinpoint bottlenecks in your code. Portability: Bytecode is why Python code can run across platforms without modification.
Jun 6, 2024 · You can use the dis module to view and analyze bytecode, gaining insights into how Python translates your code into instructions. By understanding common bytecode instructions and their role in basic Python constructs like loops and conditionals, you can optimize your code for better performance.
