A Python is a general-purpose, high-level, interpreted language with easy syntax and dynamic semantics.
- it was created by Guido van Rossum in 1989.
- Python is an object-oriented programming language, it is called interpreted language because python doesn't convert code into machine code, it simply converts the program code to bytecode.
- within python compilation happens but it's not into a machine language.
- within the environment of python the code is executing in the form of byte code.
- byte code being created and which is not further understood by the CPU.
- CPU doesn't know what is bytecode, so we actually need an interpreter.
- interpreter is a python virtual machine (PVM) is the one which executes the bytecode.
