PCEP Practice Question: Functions, Tuples, Dictionaries and Exceptions
What does the following code output?
try:
x = int('abc') except ValueError:
print('Invalid')⚠ Common exam trap
The PCEP exam often tests whether candidates understand that a caught exception does not crash the program; the trap here is that some candidates think any error causes a crash, but the except block prevents that.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Invalid
The code attempts to convert the string 'abc' to an integer using int(). Since 'abc' is not a valid integer, Python raises a ValueError. The except block catches this specific exception and executes print('Invalid'), so the output is 'Invalid'. Option B is correct because the exception is handled gracefully without crashing.
