Conver Byteccode to python and ByteCode to python

What is bytecode?

Bytecode is a low-level representation of the instructions in a programming language. In the case of Python, the CPython interpreter uses a particular kind of bytecode known as CPython bytecode. It functions as a collection of guidelines that specify the activities the interpreter should do.

dis module

The dis module, which is a component of the standard Python library, aids in the analysis of CPython bytecode. In order for you to comprehend what each instruction accomplishes, the dis module in Python is designed to disassemble or break down the bytecode into its individual instructions. Disassembling bytecode is done in order to gain a better understanding of how the interpreter runs Python code. It can be helpful for code analysis and debugging, figuring out performance snags, or discovering how specific constructs are converted into bytecode

Example

• Python

a = 1
b = 2
c = a + b
print(c)
def func(e, f, g):
    h = e + f + g

func(a, b, c)
