Which of the following is the correct way to join paths using pathlib in Python?
APath('folder') + 'file.txt'
BPath('folder') / 'file.txt'
CPath('folder').join('file.txt')
DPath('folder').append('file.txt')
Step-by-Step Solution
Solution:
  1. Step 1: Understand pathlib path joining

    In pathlib, the slash operator / is overloaded to join paths safely.
  2. Step 2: Check each option

    Path('folder') / 'file.txt' uses / correctly. Path('folder') + 'file.txt' uses + which is invalid. The .append() and .join() methods do not exist on Path objects.
  3. Final Answer:

    Path('folder') / 'file.txt' -> Option B
  4. Quick Check:

    Use slash (/) to join paths [OK]
Quick Trick: Use / operator to join pathlib paths [OK]
Common Mistakes:
  • Using + to join paths
  • Calling non-existent join or append methods
  • Forgetting to import pathlib
