What is Python Interpreter?

The program that reads and executes Python code, translating it into machine instructions at runtime.

The Python interpreter (CPython is the reference implementation) reads Python source code, compiles it to bytecode, and executes it on the Python Virtual Machine (PVM). This happens transparently each time you run a script.

Other implementations include PyPy (JIT-compiled for speed), Jython (Java platform), and IronPython (.NET platform).
