Python - File Handling Fundamentals
You want to save user settings so they are remembered next time the program runs. Which file handling approach is best?
AStore settings only in variables during program run
BWrite settings to a file and read them when program starts
CPrint settings on screen without saving
DUse file mode 'x' to read settings
Step-by-Step Solution
Solution:

  1. Step 1: Understand the need to remember data between runs

    Variables lose data when program ends, so saving to a file is needed.

  2. Step 2: Choose correct file handling method

    Writing settings to a file and reading them later keeps data persistent.

  3. Final Answer:

    Write settings to a file and read them when program starts -> Option B

  4. Quick Check:

    Persistent data = save to file [OK]
Quick Trick: Save to file to keep data after program ends [OK]
Common Mistakes:
  • Thinking variables keep data after program closes
  • Confusing file mode 'x' which creates new file
  • Assuming printing saves data
