Question

What is pickling in Python?

• A. It is used to deserialize objects, i.e., converting the byte stream to object hierarchy.
• B. It is used to serialize objects, i.e., to convert Python object hierarchy to byte stream.
• C. It is used to move the file pointer to a specific location.
• D. It is used in exception handling.

Answer 1

The Correct Option is B

Pickling is used to serialize objects, converting Python object hierarchy to byte stream.

Additional Context:

Serialization Process :

• Converts objects to byte stream for storage/transmission
• Preserves object state and structure
• Uses Python's pickle module

Key Features:

• Handles complex Python objects (lists, dicts, classes)
• Binary format (not human-readable)
• Platform-independent

Correct Answer: (2) It is used to serialize objects, i.e., to convert Python object hierarchy to byte stream.
