Python - Advanced Exception Handling

What will be the output of this code snippet?

try:
    try:
        float('xyz')
    except ValueError as ve:
        raise RuntimeError('Conversion error') from ve
except Exception as exc:
    print(type(exc).__name__)
    print(exc.__cause__)

ARuntimeError ValueError("could not convert string to float: 'xyz'")

BValueError RuntimeError('Conversion error')

CRuntimeError None

DValueError None

Step-by-Step Solution

Solution:

Step 1: Inner try-except raises RuntimeError from ValueError
The float('xyz') raises ValueError, caught and chained to RuntimeError.
Step 2: Outer except prints exception type and cause
Prints RuntimeError and the original ValueError as cause.
Final Answer:
RuntimeError ValueError("could not convert string to float: 'xyz'") -> Option A
Quick Check:
Check exception type and __cause__ attribute [OK]

Quick Trick: Exception __cause__ holds original exception instance [OK]

Common Mistakes:

Printing exception type instead of message
Assuming __cause__ is None without 'from'
Mixing up exception types and messages
