- A
It imports the package itself as a module.
Why wrong: It imports names from the package, not the package module itself.
- B
Without __all__, it imports all public names from the package's __init__.py and all submodules.
Why wrong: Without __all__, only public names from __init__.py are imported; submodules are not imported.
- C
It imports all submodules of the package by default.
Why wrong: Submodules are not imported automatically; only names from __init__.py are imported.
- D
If __all__ is defined in __init__.py, only the names in __all__ are imported.
__all__ specifies the list of names to be imported when using 'from package import *'.
- E
The behavior can be customized by defining the __all__ list in __init__.py.
Defining __all__ in __init__.py customizes which names are imported with 'from package import *'.
Quick Answer
The correct answer is that the behavior of 'from package import *' can be customized by defining the __all__ list in __init__.py. This works because when Python encounters the star import, it looks for an __all__ list within the package’s __init__.py file; if __all__ is defined, only the names listed there are imported, giving you explicit control over the module’s public interface. On the Certified Associate Python Programmer PCAP exam, this tests your understanding of package initialization and namespace management—a common trap is assuming submodules are automatically imported, but without __all__, only names explicitly defined in __init__.py are brought in, not submodules. Remember the mnemonic: “Star needs a list to shine bright—define __all__ to control the light.”
PCAP Modules and Packages Practice Question
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.
Which TWO statements about the 'from package import *' statement are correct?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
If __all__ is defined in __init__.py, only the names in __all__ are imported.
Option B is correct because the __all__ list controls which names are imported when using 'from package import *'. Option D is correct because the behavior can be customized by defining __all__ in __init__.py. Option A is wrong because submodules are not imported automatically. Option C is wrong because without __all__, only public names from __init__.py are imported, not submodules. Option E is wrong because 'from package import *' imports names from the package, not the package itself.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
