Same "see it, type it, get confirmed" loop as the bash labs — new interface, though. This runs as one continuous python3 session: variables you create in one exercise are still there a few exercises later, exactly like a real REPL.
Before We Start
Meet the Python REPL.
Typing python3 at a bash prompt drops you into a different interface entirely — the Python REPL (Read-Eval-Print Loop). It runs one line of Python at a time and shows you the result immediately, no file needed.
Its prompt looks different too: >>> means "ready for a new line." ... means Python is still waiting — you started something (like an if) that isn't finished yet.
Click inside the black box below to focus it, same as any terminal. Everything you build stays alive for the rest of this lesson, exactly like a real session.
Done
Five ideas, not fifty rules.
A value, an instruction, a decision, a repeat, borrowed code. Everything else in Python is a variation on one of those five. The dict-inside-a-dict you just pulled a value out of is exactly what a real API hands back — two lessons from now, in the Python API lab, you'll fetch one live and unpack it with these same moves.
