BSc IT - Programming in Python

• The Python Virtual Machine (PVM) is the runtime engine of Python. It's the component that executes Python bytecode.
• It's an abstraction layer, meaning it hides the complexities of the underlying operating system and hardware. This is what makes Python platform-independent.
• Essentially, the PVM interprets the bytecode, converting it into machine-understandable instructions.

It Works As:

1. Source Code:You write your Python code in a .py
2. Compilation to Bytecode:When you run the Python script, the Python compiler translates your source code into bytecode. This bytecode is a low-level, platform-independent representation of your program. Bytecode files typically have a .pyc extension (though this is often handled automatically).
3. PVM Execution:The PVM then takes this bytecode and executes it. The PVM interprets each bytecode instruction, performing the corresponding actions.

Source Code (.py) --> Compile (.pyc) --> Bytecode --> Execution --> PVM ( Python Virtual Machine ) --> Machine code
