Python Virtual Machine(PVM)

PVM in Python:

In this tutorial, you will learn what PVM means with an example. Before learning PVM let us understand about Python.

PYTHON:

Python is a programming language. Guido van Russom in the year 1991 invented Python.

Python can be used in multiple fields mainly in web development, artificial intelligence, data science, software development, etc.

Advantages of Python:

1. Simple to learn and use
2. Easy Syntax
3. User Friendly
4. Less code

 PYTHON VIRTUAL MACHINE(PVM)

Introduction:

• Python Virtual Machine(PVM) is a program that provides a programming environment. PVM is responsible for executing Python code.
• The main role of PVM is to convert the Byte code into Machine code so that the machine can understand and start execution.

Working: 

The PVM works by converting the code into machine code, represented as binary digits (0s and 1s) so that the computer can understand and produce the output.

1. Converting Source code into Byte code:

The Python compiler does this conversion. The PVM translates the Source code into Byte code with the help of a Python compiler.

2. Converting Byte code into Machine code:

Now, the Python Virtual Machine (PVM) converts this bytecode into machine code. This conversion is necessary because the machine code is understandable by the computer

Example:

a = float(input("Enter First Number:"))
b = float(input("Enter Second Number:"))
Result = a*b
print("The Product of two numbers is:", Result)

Output:

Enter First Number: 2
Enter Second Number: 3
The Product of two numbers is: 6.0

From the above example, the code is in Python language. PVM converts the source code into the machine code and the system gives the output in user-understandable language.

Advantages of PVM:

1. Easy to use: PVM is very easy to use as the tasks can be completed parallelly.
2. Scalability: PVM is said to be scalable as users can add or remove machines from virtual machines.
3. Flexibility: PVM can easily adapt to changes in the environment.
4. Cost-Effectiveness: PVM allows users to utilize the existing hardware and connecting them through PVM makes the organizations reduce cost.
5. Portable: PVM is portable, i.e. users can develop an application on one device and make the changes and execution on another device.

Conclusion:

PVM is very necessary to run any code in Python. PVM is a popular and better choice for parallel computing and its scalability and flexibility make it a different and necessary tool.
