Control Flow

4 min read Quiz at the end

Python uses if, elif, and else for decisions. Compare with ==, !=, <, >, and combine with and, or, not. The ternary form: value = 'yes' if condition else 'no' is a clean one-line conditional expression.

if / elif / else

score = 85
if score >= 90:
    grade = "A"
elif score >= 70:
    grade = "B"
else:
    grade = "C"
print(grade)  # B

# One-liner ternary
result = "pass" if score >= 50 else "fail"
