Step-by-Step Solution
Solution:

  1. Step 1: Understand case sensitivity in Python variable names

    Python treats 'name' and 'Name' as two different variables because variable names are case sensitive.

  2. Step 2: Check the print statement

    It concatenates the value of 'name' ('Alice') with ' and ' and then the value of 'Name' ('Bob').

  3. Final Answer:

    Alice and Bob -> Option B

  4. Quick Check:

    Python variable names are case sensitive = Alice and Bob [OK]
Quick Trick: Variable names differ by case are different variables [OK]
Common Mistakes:
MISTAKES
  • Assuming variable names are case insensitive
  • Expecting error due to similar names
  • Confusing variable values
