Interpreted Programming language- Part 2 (Interpreted)

Interpreted programming language where code is executed directly by an interpreter, line by line , without the need for a separate compilation step.

So question arises how interpreter convert source code to machine code?

Here come in frame Bytecode (like pycache, .pyc)

• It is like middleman between source code and machine code.
• It's mot directly readable by CPU, but its much easier for the interpreter or a virtual machine (like the python virtual machine -PVM) to executed.
• Think of it like a simplified version of machine code, portable and platform independent.

If we can compile directly to machine code make an executable why do some language like python use bytecode in between?

Here is an analogy:-
Direct Translation (Machine Code)

You hire someone to translate your English book directly into Chinese, Hindi, German etc. for each country.

This is like C/C++ where source code is compiled directly into machine code for each platform.

Translate to Universal Language (Bytecode)

Instead of translating your book to every local language, you translate it once into a universal language, like Esperanto or symbolic shorthand.

This is like python or java, where your code is translated into bytecode, and each machine uses its own interpreter (like the python virtual machine or java virtual machine) to understand it.
