Reviewing Python 3 Syntax Through an Annotated Image

Previously we shared an image containing a short Python code snippet that incorporated most of Python's basic syntax with explanatory annotations, allowing readers to review key language concepts.

However, that image was based on Python 2, and many of its constructs are no longer valid in Python 3.

To address this, a new image based on Python 3 syntax has been created for learners to reference.

Key topics covered in the image include output, input, variables, assignment, calculations, modules, functions, parameters, return values, indentation, comments, for‑loops, conditional statements, logical operations, string formatting, escape characters, type conversion, lists, and a brief introduction to object‑oriented usage such as calling object methods.
