Python - Advanced Exception Handling

Identify the error in this code snippet:

try:
    int('abc')
except ValueError as e:
    raise TypeError('Wrong type') from
AValueError because int conversion failed
BTypeError because 'from' cannot be used here
CNo error, code runs fine
DSyntaxError due to incomplete 'from' statement
Step-by-Step Solution
Solution:
  1. Step 1: Check the 'raise' statement syntax

    The statement ends with 'from' but does not specify the original exception after it.
  2. Step 2: Understand Python syntax rules

    The 'from' keyword must be followed by an exception instance or variable; missing this causes SyntaxError.
  3. Final Answer:

    SyntaxError due to incomplete 'from' statement -> Option D
  4. Quick Check:

    Incomplete 'from' causes SyntaxError [OK]
Quick Trick: Always provide an exception after 'from' [OK]
Common Mistakes:
MISTAKES
  • Leaving 'from' without exception
  • Thinking 'from' is optional
  • Confusing runtime error with syntax error
