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.
Exhibit
Exhibit:
Project structure:
main.py
utils/
__init__.py
helpers.py
strings/
__init__.py
format.py
# main.py
from utils.helpers import greet
from utils.strings.format import bold
Refer to the exhibit. Given the project structure, which of the following import statements in main.py would cause an ImportError?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
from ..utils import helpers
Option B uses a relative import with '..' which is only valid inside a package (i.e., when the module is loaded as part of a package and has a __package__ attribute set). In a flat project structure where main.py is a top-level script, '..' attempts to go above the top-level package, which is not allowed and raises an ImportError. Python's import system requires that relative imports be used only within a package hierarchy.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
from utils import strings
Why it's wrong here
Valid; imports the strings subpackage as a name.
✓
from ..utils import helpers
Why this is correct
Correct. Relative imports like '..' are allowed only inside a package; main.py is the top-level script.
Related concept
Read the scenario before looking for a memorised answer.
✗
from utils import helpers
Why it's wrong here
This is a valid absolute import; utils is a subdirectory with __init__.py.
✗
from utils.strings import format
Why it's wrong here
Valid absolute import; utils.strings is a subpackage.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Python Institute often tests the distinction between absolute and relative imports, trapping candidates who assume that '..' works in any script, when in fact relative imports are only valid inside a package and fail with an ImportError when used in a top-level script.
Detailed technical explanation
How to think about this question
Relative imports rely on the __package__ attribute of the importing module, which is set only when the module is loaded as part of a package (e.g., via 'python -m package.main'). When running a script directly with 'python main.py', __package__ is None, so any relative import (using '.' or '..') triggers a 'SystemError: Parent module '' not loaded, cannot perform relative import' or an ImportError. This behavior is defined in PEP 328 and is enforced to prevent ambiguity in module resolution.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
