Types you can see

This is Python · easy, lesson 1: Types you can see. Read the teaching and the stills before the checks. The quizzes are open book and test the subject — Python itself — not product rules or layout trivia.

You already finished Introductory. I will not re-teach the absolute first hello. We build upward.

type(3) is int; type(3.5) is float; type("a") is str. Booleans are True and False.

Floats are binary approximations — careful with money.

Use isinstance for checks. TypeError means wrong kind of value.

Naming types aloud predicts which operations are legal.

print(type(3))
print(type(3.5))
print(type("a"))

Sit with that still. Trace it top to bottom. Name each piece. The exercise asks you to match its essence.

If something fails when you try it yourself, change one thing. Read the error. Return to the still. I will not rush you.

That is the lesson. When every quiz and exercise on this page is green, mark it passed. Next lesson when you are ready.
