Conditionals: Misconceptions

Misconceptions

Test common incorrect explanations against definitions, conservation rules and evidence.

This extension applies that lens specifically to Conditionals.

Conditionals run code only when a condition is true:

if age >= 18:
    print("adult")
elif age >= 13:
    print("teen")
else:
    print("child")

The comparison operators produce a bool: == equal, != not equal, <, >, <=, >=. Indentation (4 spaces) is how Python knows which lines belong inside the if.

Code practice

Python Foundations — Misconceptions: Write classify(n) that returns "positive" if n is greater than 0, "negative" if less than 0, and "zero" otherwise.

Code practice

Python Foundations — Misconceptions: For the given age = 20, set is_adult to a bool that is True when age is at least 18.
