The document explains the function of a Python compiler and the Python Virtual Machine (PVM) in converting source code into byte code and then into machine code for execution. It outlines the process: the IDE writes source code, the compiler generates byte-code, and the PVM interprets and converts it into machine code for the processor. The PVM, also referred to as an interpreter, plays a crucial role in this conversion and execution process.

2. To

3. A python compiler dose the same task
but in a slightiy different manner.
It converts the program source code
into another code,called byte code.
The python program statement is
convered into a group of byte code
instructions.
python virtual machine:

4. PVM:
It is program which provides
programming envirnment.

It converts python byte-code
instructions into machine code.

9. python organization saya that ther may be newer
unstruction added to the existing byte code instrutions
from time to time ne can find byte code instruction in
the pyc file.
The role of virtual machine in converting byte code
instruction into machine code.

Python virtual machine(PVM)

11. role of python virtual(PVM) is to convert the byte
code instructions into machine code.
so that the computer can execute those machine
code instructions and display the final output.
To carry out this conversion,PVM is equipped
with an interpreter.

12. Interpreter converts the byte code into
machine code and sends that machine code to
the computer processor for execution.
Since interpreter is playing the main role,
often the python virtual machine is also called an
interpreter.
