Python - Modules and Code Organization

Given this folder structure and files:

mypackage/
  __init__.py
  module.py

# __init__.py content:
print('Package imported')

# module.py content:
def greet():
    return 'Hello!'

# main.py content:
import mypackage
from mypackage import module
print(module.greet())

What will be the output when running main.py?

AHello!\nPackage imported

BPackage imported\nHello!

CHello!

DImportError

Step-by-Step Solution

Solution:

Step 1: Understand import behavior
When import mypackage runs, the code inside __init__.py executes, printing 'Package imported'.
Step 2: Check subsequent import and function call
Then from mypackage import module imports the module, and print(module.greet()) prints 'Hello!'.
Final Answer:
Package imported Hello! -> Option B
Quick Check:
Init runs first, then greet() output = A [OK]

Quick Trick: Code in __init__.py runs on package import [OK]

Common Mistakes:

Assuming __init__.py code does not run
Mixing order of printed lines
Expecting ImportError without reason
