Python - Standard Library Usage
Why does adding two datetime objects in Python cause an error?
ABecause datetime objects cannot be created without timezone info
BBecause datetime objects represent points in time, not durations
CBecause datetime objects are immutable and cannot be changed
DBecause datetime objects require string conversion before addition
Step-by-Step Solution
Solution:
  1. Step 1: Understand what datetime objects represent

    Datetime objects represent specific points in time, not durations.
  2. Step 2: Understand why addition is invalid

    Adding two points in time is undefined; only adding durations (timedelta) to datetime is valid.
  3. Final Answer:

    Datetime objects represent points in time, not durations -> Option B

    Cannot add two datetime points; add timedelta instead [OK]
Quick Trick: Add timedelta to datetime, not datetime to datetime [OK]
