Python - Modules and Code Organization

You have a folder named utils with a file helper.py inside. You try to import helper using import utils.helper but get ModuleNotFoundError. What is the most likely cause?

AThe <code>helper.py</code> file has syntax errors

BThe <code>helper.py</code> file is empty

CYou need to run Python with administrator rights

DThe <code>utils</code> folder is missing <code>__init__.py</code>

Step-by-Step Solution

Solution:

Step 1: Understand package import requirements
Python requires an __init__.py file in a folder to treat it as a package for imports like utils.helper.
Step 2: Identify cause of ModuleNotFoundError
If __init__.py is missing, Python does not recognize utils as a package, causing the error.
Final Answer:
The utils folder is missing __init__.py -> Option D
Quick Check:
Missing __init__.py causes import error = D [OK]

Quick Trick: Always add __init__.py to folders for imports [OK]

Common Mistakes:

MISTAKES

Blaming syntax errors without checking
Thinking admin rights affect imports
Assuming empty files cause import failure
