How to Serialize a Python Object to Pickle Bytes in Memory

import pickle

class Person:
    def __init__(self, name, age, skills):
        self.name = name
        self.age = age
        self.skills = skills

def main():
    person = Person("Alice", 30, ["Python", "SQL", "Docker"])
    
    # Serialize to bytes in memory
    pickle_bytes = pickle.dumps(person)
    
    print(f"Serialized bytes length: {len(pickle_bytes)} bytes")
    print(f"First 20 bytes: {pickle_bytes[:20]}")
    
    # Deserialize back from bytes
    restored_person = pickle.loads(pickle_bytes)
    
    print(f"\nRestored object attributes:")
    print(f"  Name: {restored_person.name}")
    print(f"  Age: {restored_person.age}")
    print(f"  Skills: {restored_person.skills}")
    print(f"  Type: {type(restored_person).__name__}")
    
    # Verify equality of attribute values
    assert person.name == restored_person.name
    assert person.age == restored_person.age
    assert person.skills == restored_person.skills
    print("\nAll attributes match after roundtrip!")
