Compilation

The program is converted into byte code. Byte code is a fixed set of instructions that represent arithmetic, comparison, memory operations, etc. It can run on any operating system and hardware. The byte code instructions are created in the .pyc file. The .pyc file is not explicitly created as Python handles it internally but it can be viewed with the following command:

-m and py_compile represent module and module name respectively. This module is responsible to generate .pyc file. The compiler creates a directory named  __pycache__ where it stores the first.cpython-38.pyc file. 

This article aims at providing a detailed insight into the execution of the Python program. Let’s consider the below example.

Example:

Output:

Sum  20

Suppose the above python program is saved as first.py. Here first is the name and .py is the extension. The execution of the Python program involves 2 Steps:

• Compilation
• Interpreter
