In a Raspberry Pi web server script, a function meant to handle requests is not called. What could be a common coding mistake?
AThe route decorator is missing above the function.
BThe function name is too long.
CThe Raspberry Pi is not connected to Wi-Fi.
DThe function uses too many variables.
Step-by-Step Solution
Solution:

  1. Step 1: Understand how web servers link URLs to functions

    Functions must have route decorators to be called on matching requests.

  2. Step 2: Identify missing decorator effect

    Without the decorator, the server does not know to call the function for any URL.

  3. Final Answer:

    The route decorator is missing above the function. -> Option A

  4. Quick Check:

    Missing decorator = function not called [OK]
Quick Trick: Always add route decorators to handler functions. [OK]
Common Mistakes:
MISTAKES
  • Thinking function name length matters
  • Blaming Wi-Fi for code logic errors
  • Assuming variable count stops function call
