PCEP Computer Programming and Python Fundamentals Practice Question

Exhibit

try:
    x = int("hello")
except ValueError:
    print("Invalid integer")
except:
    print("Some error")

Refer to the exhibit. What is the output?

⚠ Common exam trap

Candidates may think that after catching an exception, the program continues to execute code that follows the try-except block, but in this question there is no such code. The trap is recognizing that the output consists solely of the print inside the except.

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 integer

The code attempts to convert the string '12.5' to an integer using int(). Since '12.5' is not a valid integer literal (it contains a decimal point), Python raises a ValueError. The exception is caught by the except clause, which prints 'Invalid integer'. After the try-except block, there is no further print statement, so the only output is 'Invalid integer'.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
Invalid integer\nSome error
Why it's wrong here
Only one except block runs.
✗
No output
Why it's wrong here
An exception is raised and caught, so a message is printed.
✗
Some error
Why it's wrong here
The generic except is not executed because ValueError is caught first.
✓
Invalid integer
Why this is correct
The specific ValueError handler runs.
