Python - Magic Methods and Operator Overloading
Find the error in this code:
numbers = [1, 2, 3]
for i in len(numbers):
    print(numbers[i])
Anumbers[i] is invalid syntax
Bprint() cannot be used inside loop
CMissing colon after for loop
Dlen(numbers) is not iterable
Step-by-Step Solution
Solution:
  1. Step 1: Identify the problem with for loop

    The for loop tries to iterate over len(numbers), which is an integer, not a sequence.
  2. Step 2: Correct way to iterate by index

    Use for i in range(len(numbers)): to loop over indexes.
  3. Final Answer:

    len(numbers) is not iterable -> Option D
  4. Quick Check:

    len() returns int, not iterable [OK]
Quick Trick: Use range(len()) to loop by index, not len() alone [OK]
Common Mistakes:
MISTAKES
  • Using len() directly in for loop
  • Confusing len() with range()
  • Syntax errors in loop
  • Misunderstanding iterable types
