You want to safely convert user input to an integer and print it. Which code correctly handles invalid input without crashing?
Atry: num = int(input()) except ZeroDivisionError: print('Invalid number')
Bnum = int(input()) print(num)
Ctry: num = int(input()) except ValueError: print('Invalid number')
Dnum = input() print(int(num))
Step-by-Step Solution
Solution:
  1. Step 1: Understand input conversion risks

    User input may not be a valid integer, causing ValueError on conversion.
  2. Step 2: Check exception handling

    try: num = int(input()) except ValueError: print('Invalid number') uses try-except to catch ValueError and print a message, preventing crash.
  3. Final Answer:

    try-except catching ValueError with message -> Option C
  4. Quick Check:

    Handle invalid input with ValueError catch [OK]
Quick Trick: Use try-except to catch ValueError on int conversion [OK]
Common Mistakes:
  • Not catching exceptions causing program crash
  • Catching wrong exception type like ZeroDivisionError
  • Assuming input is always valid integer
