Python - Polymorphism and Dynamic Behavior

Write a polymorphic function describe that returns:
- "Number: <value>" if input is int or float
- "Text: <value>" if input is str
- "List of length <length>" if input is list
- "Unknown" otherwise

What will describe([1, 2, 3]) return?

A"List of length 3"

B"List of length [1, 2, 3]"

C"Unknown"

D"Number: [1, 2, 3]"

Step-by-Step Solution

Solution:

Step 1: Understand function behavior for list input
For list input, function returns 'List of length ' plus length of list.
Step 2: Calculate length of [1, 2, 3]
Length is 3, so output is 'List of length 3'.
Final Answer:
"List of length 3" -> Option A
Quick Check:
Polymorphic describe returns list length string for list input [OK]

Quick Trick: Use isinstance and len() to handle lists in polymorphic functions [OK]

Common Mistakes:

MISTAKES

Returning list itself instead of length
Confusing list with string
Returning Unknown for list input
