Answer - Python mostly used in scripting, is general purpose programming language which supports OOP Object oriented programming principles as supported by C++, Java, etc. Python programs are written to files with extension .py . These python source code files are compiled to byte code (python specific representation and not binary code), platform independent form stored in .pyc files. These byte code helps in startup speed optimization. These byte code are then subjected to Python Virtual Machine PVM where one by one instructions are read and executed. This is interpreter.
