Conditions

A condition lets a program make a decision — run one block of code if something is true, and a different block if it's not.

Real-world analogy: "if it's raining, take an umbrella; otherwise, leave it at home." The program checks a condition and picks a path.

if age >= 18:
    print("Adult")
else:
    print("Minor")

Practice

Describe, in plain steps, how a program would decide whether a number is positive, negative, or zero.

if number > 0: it's positive
else if number < 0: it's negative
else: it's zero
