Python Fundamentals in one look

the smallest pieces a program is built from, before a single line runs

Python is interpreted

Python translates and runs one statement at a time, so a program needs no separate compile step before it runs
this makes errors easy to trace, execution simply stops right at the line that failed
the interpreter that ships with Python is the reference one, called CPython

Interactive mode vs Script mode

Interactive mode

the triple greater-than prompt, type one statement, see its result right away
great for testing a small snippet, nothing here is saved automatically

Script mode

statements written in a .py file, run all at once from top to bottom
saved, reusable, and shareable, the normal way any real program is written

The IDE, at a glance

Editor window: where a .py file is written and saved
Shell window: the interactive prompt, for quick one-line checks
Run: executes the whole saved script in one go

How CapCompass uses this sheet

These notes are not a standalone PDF. CapCompass plans Computer Science chapter by chapter against your real exam dates and free hours, and when the plan reaches Python Fundamentals the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
