Question 132 of 498
PCEP Practice Question: Functions, Tuples, Dictionaries and Exceptions
Exhibit
Refer to the exhibit.
config = {
'host': 'localhost',
'port': 8080,
'timeout': 30
}
try:
value = config['debug']
except KeyError:
print('Key not found')What is the output of the code?
⚠ Common exam trap
The PCEP exam often tests the distinction between `dict[key]` (which raises `KeyError`) and `dict.get(key, default)` (which returns the default), trapping candidates who expect an exception or assume the default is `None`.
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
✓
Key not found
The code uses a dictionary's `get()` method with a default value of 'Key not found'. When the key 'b' is not present in the dictionary `d`, `get()` returns the specified default instead of raising an exception. Therefore, the output is 'Key not found', making option D correct.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AttributeError
Why it's wrong here
AttributeError is not raised because the code uses the get() method, which does not raise an exception for missing keys.
- ✗
The program exits with no output
Why it's wrong here
The program does produce output because get() returns a default value.
- ✗
None
Why it's wrong here
The default value is not None because the get() call specifies 'Key not found' as the default.
- ✓
Key not found
Why this is correct
The get() method returns the default value 'Key not found' when the key is absent, so this is printed.
