easy🧠 Conceptual Q2 of Q15
Python - Multiple Inheritance and Method Resolution
What happens if you define a class with multiple inheritance but forget to include parentheses after the class name?
AIt inherits only from the first class listed
BIt creates a class with no parents (inherits from object)
CIt inherits from all classes listed after colon
DIt causes a syntax error
Step-by-Step Solution
Solution:
  1. Step 1: Recall Python class definition syntax

    Parent classes must be listed inside parentheses immediately after the class name.
  2. Step 2: Understand consequences of missing parentheses

    Without parentheses, Python expects no inheritance and syntax is invalid if you try to list parents after colon.
  3. Final Answer:

    It causes a syntax error -> Option D
  4. Quick Check:

    Missing parentheses in multiple inheritance = syntax error [OK]
Quick Trick: Always put parentheses after class name for inheritance [OK]
Common Mistakes:
MISTAKES
  • Omitting parentheses when inheriting
  • Listing parents after colon instead of parentheses
