How does python bytecode works?

Nope. The CPython Python interpreter is written in (as portable as 
possible) C. The Jython, IronPython, and PyPy Python interpreters are 
written in Jave, C#, and Python respectively. Each compiles Python to 
something different. I presume each (normally) saves the compiled form 
until the source changes. CPython compiles to CPython-specific bytecode. 
It saves the bytecode as a .pyc file in a .__cache__ subdirectory (in 3.2+).

Yes it is (mostly). CPython has been compilied, with minor adjustments, 
on numerous (>20) systems.

The website has a Python interpreter.

The Python interpreter of the website *does* compile Python code to 
whatever it compiles to.
