Define Compiler, Interpreter, Linker & Loader in PYTHON


Compiler :

                        It is a software that translates a program written in a high-level language into machine language. This compiled program is called object code. The object code is an executable code which can run as a standalone code, i.e. it does not need the compiler to be present during execution. Every programming language, such as C, C++ and Java has its own compiler.



Interpreter :

                      While a compiler converts the whole source code into an equivalent object code or machine code, the interpreter reads the source code line by line and converts it into object code (i.e. a code understandable to the machine.



Linker :

             It is a program that links different program modules and libraries to form a single executable program. A source code of a program is very large. It can consist of hundreds of lines of code. Before the execution of a program, all the modules of the program and the required libraries are linked together using a software called a linker. The compiled and linked program is called the executable code.


Loader :

             This software is used to load and relocate and executable program in the main memory during execution. The loader assigns a storage space to a program in the main memory for execution.

Python Implementations

  The standard implementation of Python is usually called "CPython" . It is the default and widely used implementation of the Python programming language. It is written in C. Besides C, there are different implementation alternatives of Python, such as Jython, IronPython, Stackless and PypY . All these Python implementations have specific purpose and roles. All of them make use of simple Python language but execute programs in different ways. Different Python implementations are briefly explained ahead. Jython Originally, Jython was known as "JPython". JPython takes Python programming language syntax and enables it to run on the platform. In short, it is used to run Python programs on Java platforms. More details about JPython can be found at http://jPython.org. IronPython IronPython is an open source implementation of Python for the .NET framework. It uses dynamic language runtime (DLR) , which is a framework for writing dynamic languages for .net . A major use o...
