Compiler-total line code run (java)
Interpreter -line by line execute(Python)
PYTHON
Python is a high-level, general-purpose programming language.
It is an interpreted language, meaning code is executed line by line.
Speeds up the development process.
Key Features of Python:
1.Easy to Learn and Read
2.Interpreter Language
3.Free and Open source

4.Control Structure (eg.if,else,etc..)
5.Libraries(eg.Numpy,Pandas)
Python version:
Python 2.7(lack of support for this version)
Python 3.13(new project only)
Editor:
1.IDLE(beginners and basic scripting)
2.Pycharm(powerful)
3.Sublime Text(fast and highly customisable)
