This PCAP practice question tests your understanding of modules and packages. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A developer creates a package named 'mypkg' with an __init__.py file. Inside the package, there is a module 'utils.py'. Which of the following is the correct way to import the function 'helper' from 'utils' from outside the package?
import mypkg.utils.helper
Why wrong: Must use 'from...import' to import a function directly.
import mypkg; mypkg.utils.helper
Why wrong: Requires 'import mypkg.utils' first, then 'mypkg.utils.helper'.
from mypkg.utils import helper
Correct dot notation to import from a submodule.
from mypkg import utils.helper
Why wrong: Invalid syntax; 'utils.helper' is not a top-level attribute of 'mypkg'.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
from mypkg.utils import helper
Option C is correct because it uses the standard Python syntax for importing a specific name from a submodule within a package: `from package.module import name`. This directly imports the `helper` function into the current namespace, making it callable without any prefix. The `__init__.py` file marks `mypkg` as a package, and `utils.py` is a module inside it, so `from mypkg.utils import helper` is the proper way to access `helper` from outside the package.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Python Institute often tests the distinction between importing a module versus importing an attribute from a module, and the trap here is that candidates confuse the `import` statement (which only accepts modules/packages) with the `from ... import` statement (which can import any object), leading them to choose Option A or D.
Detailed technical explanation
Under the hood, Python's import system treats packages as modules with a `__path__` attribute, and submodules are loaded lazily. When you use `from mypkg.utils import helper`, Python first imports `mypkg` (executing its `__init__.py`), then imports `mypkg.utils` (executing `utils.py`), and finally binds the name `helper` in the current namespace to the function object. A subtle behavior is that if `mypkg.__init__.py` contains `from .utils import helper`, then `import mypkg` alone would make `mypkg.helper` accessible, but that is not the case here. In real-world scenarios, this pattern is essential for organizing large codebases, as it allows selective imports to avoid namespace pollution and improve readability.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
