The Python interpreter first reads the human code and optimizes it to some intermediate code before interpreting it into machine code. That's why you always need another program to run a Python script, unlike in C++ where you can run the compiled executable of your code directly. For example, c:\Python27\python.exe or /usr/bin/python.
Feb 26, 2012 · Python does not need a compiler because it relies on an application (called an interpreter) that compiles and runs the code without storing the machine code being created in a form that you can easily access or distribute.
Jul 11, 2015 · As far as I know, you cannot execute a Python program (compiled to bytecode) on any Windows or Linux machine without modification. Yes, you can. The CPython VM is available for both Windows and Linux, as is PyPy, Jython and IronPython.
- Cython. Cython is a C language-based compiler written in Python and C. It is the default compiler for Python. Advantages of Cython. It is the most widely used compiler.
- Jython. Jython is a Java-based compiler written in Python and Java. Unlike Cython, it compiles to a .class file and can be used with Java Virtual Machine.
- PyPy. Armin Rigo developed PyPy using only Python programming language to replace the default compiler, Cython and released it in 2007. Advantages of PyPy.
- IronPython. Jim Hugunin developed the IronPython using the language C# to integrate Python code with the .Net framework, and Mono and released it in September 2006.
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.
Depending on your definition, native machine compilers for Python exist. Some only compile a subset of python. Others implement all of python but use the python API to actually perform the operations which it cannot perform in C.
Dec 28, 2022 · Typing the word python into the command prompt invokes the Python Interpreter, which is the program you are actually running. It simply takes your script (as the argument) to be processed further. The Python Interpreter itself consists of two parts: a compiler and the Python Virtual Machine (PVM).
