Solution:

  1. Step 1: Recall file modes in Python

    'r' mode opens a file for reading, 'w' for writing, 'x' for creating, 'a' for appending.

  2. Step 2: Match mode with reading requirement

    Since we want to read the file, 'r' mode is correct.

  3. Final Answer:

    open('data.txt', 'r') -> Option C

  4. Quick Check:

    Read mode = 'r' [OK]
Quick Trick: Use 'r' mode to open files for reading [OK]
Common Mistakes:
  • Using 'w' which overwrites file
  • Using 'a' which appends instead of reading
  • Confusing 'x' with reading mode
