Python - Operators and Expression Evaluation
In Python, what does the is operator determine when used between two variables?
AWhether both variables are of the same data type
BWhether both variables have the same value
CWhether both variables point to the exact same object in memory
DWhether both variables are not equal
Step-by-Step Solution
Solution:

  1. Step 1: Understand the is operator

    The is operator checks if two variables reference the same object in memory, not just if their values are equal.

  2. Step 2: Differentiate from ==

    The == operator compares values, but is compares identities (memory locations).

  3. Final Answer:

    Whether both variables point to the exact same object in memory -> Option C

  4. Quick Check:

    is checks identity, not equality [OK]
Quick Trick: Use 'is' for identity, '==' for equality [OK]
Common Mistakes:
MISTAKES
  • Confusing 'is' with '==' operator
  • Assuming 'is' checks value equality
  • Thinking 'is' compares data types
