The methods used in generating parse trees and syntax trees from source code are language-agnostic, so we do not spend much time on these.

Interpreting: This involves the execution of the generated code object’s bytecode within some context.

Compiling: This involves activities such as building syntax trees from source code, creating the abstract syntax tree, building the symbol tables, generating code objects etc.Initialization: This step covers the set up of the various data structures needed by the Python process and is only relevant when a program is executed non-interactively through the command prompt.The relevant stages depend on how the interpreter is invoked, and this write-up covers them in different measures:

I regard the execution of a Python program as split into two or three main phases, as listed below. Other implementations include PyPy - Python implemented in a restricted subset of Python, Jython - Python implemented on the Java Virtual Machine, etc. Python and CPython are used interchangeably in this text, but any mention of Python refers to CPython, the version of Python implemented in C. It targets CPython, the most popular, and reference implementation of Python at the point of this write-up. This write-up looks at the nuts and bolts of the Python interpreter. Guido van Rossum started development work on the first version in 1989, and it has since grown to become one of the more popular languages used in a wide range of applications from graphical interfaces to finance and data analysis. The Python Programming language has been around for a long time. 10.1 A Short Note on Exception Handling.5.2 Code Objects within other code objects.3.3 From Parse Tree To Abstract Syntax Tree.
