A software system reads data from various sources. Whenever there's corrupted data, you want to log it and continue processing other data. How would you design the exception handling mechanism?
- Ignore corrupted data completely and proceed with the remaining data without logging.
- Implement a separate error-handling thread to handle data corruption without stopping processing.
- Stop processing data as soon as corruption is detected to prevent further issues.
- Use try-except blocks to catch and log exceptions, then continue processing unaffected data.
The correct approach is to use try-except blocks to catch and log exceptions while continuing to process unaffected data. This ensures data integrity and allows for identifying and handling corrupted data while not halting the entire process.

Which memory management technique does Python primarily utilize?
- Garbage Collection (GC)
- Manual Memory Management (malloc/free)
- Reference Counting
- Stack Allocation
Python primarily utilizes Garbage Collection (GC) for memory management. It automatically deallocates memory occupied by objects that are no longer in use, making memory management more convenient and reducing the risk of memory leaks.
Which Python module provides functionality to read and write data in CSV format?

When using the setdefault method on a dictionary, what happens if the provided key already exists in the dictionary?
- A new key-value pair is added with the default value
- An error is raised
- The existing key-value pair is overwritten with the default value

When setdefault is called with an existing key, it doesn't modify the existing value but returns it. If the key doesn't exist, it adds the key with the provided default value.
Which of the following set methods does not modify the set but returns a new set?
- difference()
- intersection()
- issubset()
- union()
The union() method returns a new set that contains all the elements from both sets without modifying the original sets.
