Answer Key

break and continue

Section A: Quick Questions

B — Exits the loop immediately

A — Skips to the next iteration

B — 0, 1, 2

A — 0, 1, 2, 4

A — No causes SyntaxError

Section B: Match the Pairs

break → Error: break outside loop

for i in range(5): continue print(i) → Error: print never reached

for i in range(5): if i == 3: break → Valid: break exits at i==3

for i in range(5): if i == 2: continue print(i) → Ok: Skips printing 2

for i in range(5): if i == 3: break print(i) → Output: 0 1 2

for i in range(4): if i == 2: continue print(i) → Output: 0 1 3

Section C: Definitions

break — Immediately exits the entire loop.~~continue

Section D: Fill in the Blanks

for i in range(10):
    if i == 5:
        break
    print(i)

for i in range(10):
    if i == 3:
        continue
    print(i)

while True:
    x = input('Enter: ')
    if x == 'quit':
        break

for i in range(10):
    if i % 2 == 0:
        continue
    print(i)

for i in range(20):
    if i == 10:
        break
    print(i)

Section E: Spot the Error

A — break must be INSIDE a loop: it can't be used outside

C — break must be lowercase Break is not valid Python

C — continue must be lowercase Continue is not valid Python

C — break must be indented inside the if block

C — break is a keyword, not a function don't use parentheses
