200-901 Question 169
Single answerA development team is collaborating on a Python script stored in a Git repository. A teammate has submitted a pull request, and you are reviewing the changes using the unified diff format. The diff output for one of the files is shown below:
@@ -10,7 +10,7 @@ def calculate_sum(a, b): # Perform addition return a + b
-# Removed debug print statement +# Added logging functionality import logging logging.basicConfig(level=logging.INFO)
What does the unified diff indicate about the changes made to the file?
- A
A debug print statement was removed, and logging functionality was added.
- B
The calculate_sum function was removed and replaced with logging functionality.
- C
Logging functionality was added, but there were no changes to the calculate_sum function.
- D
The calculate_sum function was modified to include logging functionality.
Show answer and explanation
Correct answer: A
Explanation
Unified diff format shows changes in a file with '-' indicating removed lines and '+' indicating added lines. In this case, the diff indicates that a debug print statement was removed and replaced with logging functionality. There are no changes to the calculate_sum function itself.
- A. Correct.
This is correct because the unified diff shows that a debug print statement was removed (line starting with '-') and logging functionality was added (line starting with '+').
- B. Incorrect.
This is incorrect because the calculate_sum function was not removed or replaced. The changes only pertain to adding logging functionality.
- C. Incorrect.
This is incorrect because the calculate_sum function remains unchanged, but the diff explicitly shows that a debug print statement was removed.
- D. Incorrect.
This is incorrect because the calculate_sum function was not modified; the changes only involved removing a debug print statement and adding logging functionality.
