Introduction

Actually Python is both interpreted and compiled language. The question is how Python run the code.

• 1. So, at first we write a Python code stored in a file with .py extension. Then a compiler compiled the source code into special byte code at that time the compiler also checks the Python syntax.
• 2. The Python compiler compiled the code behind the scene so we don't have to compile it manually.
• 3. The byte code is not understand by cpu.
• 4. Now, there is an Interpreter which is also called Python Virtual Environment(PVM) which takes that byte code and read the byte code line by line (one line at a time) and convert that byte code into Machine Code.
• 5. Here we use byte code for portability.So every computer should have virtual machine (PVM) to interpreted that byte code.
• 6. The python code we write is actually CPython.
• 7. All language have one compiling phase. So, no language is only interpreted that language is also compiled.
