  1. Aug 13, 2020 · Both Java and python (talking about CPython only) are interpreted to Java and CPython bytecode respectively. Both bytecodes are then interpreted by their respective virtual Machines (JVM & Cpython VM).

  2. Sep 6, 2024 · CPython has 1. a source-to-bytecode compiler and 2. a bytecode interpreter. Java has 1. a source-to-bytecode compiler and 2. a JIT compiler. You can focus on the first part and consider both to be compiled.

    • Introduction to CPython. When you type python at the console or install a Python distribution from python.org, you are running CPython. CPython is one of the many Python runtimes, maintained and written by different teams of developers.
    • The Python Interpreter Process. Now that you’ve seen the Python grammar and memory management, you can follow the process from typing python to the part where your code is executed.
    • The CPython Compiler and Execution Loop. In Part 2, you saw how the CPython interpreter takes an input, such as a file or string, and converts it into a logical Abstract Syntax Tree.
    • Objects in CPython. CPython comes with a collection of basic types like strings, lists, tuples, dictionaries, and objects. All of these types are built-in.
  3. Jul 31, 2024 · The interpreter executes the bytecode and generates machine code on the fly. This allows bytecode to be run on any machine without needing the original source code, as long as the machine has the appropriate interpreter installed. Python's Code Execution. The Python interpreter is responsible for executing Python programs.

  4. For this reason, Java is often called a compiled language, while Python is called an interpreted language. But both compile to bytecode, and then both execute the bytecode with a software implementation of a virtual machine. Another important Python feature is its interactive prompt.

  5. Sep 27, 2020 · what i know is , in cpython when we run a code then its first compiled into byte code and the cpython interpreter ( which is written in c interprets it) interprets the byte code and converts it into machine code. Does that mean the byte code is represented as c code by the interpreter and then its carried out as c code ?

  7. At the start of program execution, it is indeed similar, with the HotSpot VM interpreting Java bytecode. However, HotSpot also JIT compiles performance-critical parts of the code directly into native machine code. CPython doesn't do JIT compilation. There was an experimental project to add this feature, but it didn't work out in the end.
