Conditionals — Controlling Program Flow with if/elif/else

Every decision your tool makes — allow or block, scan or skip, alert or ignore — starts here.

Basic Syntax

age = 18

if age >= 18:
    print("you are an adult")
else:
    print("you are a minor")

Multiple Conditions

score = 85

if score >= 90:
    grade = "A"
elif score >= 80:
    grade = "B"
elif score >= 70:
    grade = "C"
else:
    grade = "F"

Nested Conditionals

if user == "admin":
    if password == "secret":
        print("access granted")
    else:
        print("wrong password")
else:
    print("unknown user")

Truthy and Falsy Values

# Falsy values:
# False, None, 0, 0.0, "", [], {}, ()

if []:
    print("this won't run")

name = ""
if not name:
    print("name is empty")

Ternary Operator

status = "active" if logged_in else "inactive"
