Python Oops Garbage Collection

Question 1

In python, what happens to the memory occupied by the objects that are garbage collected.

Memory is immediately released and made available for reuse.

Memory is marked as empty but not immediately reusable.

Memory is kept reserved indefinitely.

Memory is automatically reallocated to other objects.

Question 2

What is the primary purpose of garbage collection in python?

To optimize memory usage.

To improve code execution speed.

To manage global variables.

To handle exceptions efficiently.

Question 3

How dose python's garbage collector determine if an object is eligible for garbage collection?

Reference counting mechanism.

Using the mark and sweep algorithm.

Objects are collected randomly.

Objects are explicitly marked for collection.

Question 4

What is garbage collection in python?

A process of automatically deallocating memory of unused objects.

A process of managing global variables.

A process of optimizing class methods.

A process of handling exceptions in python.

Question 5

Which statement about cyclic references and garbage collection in python is true?

A. Cyclic references can be automatically detected and collected by python's garbage collector.

Cyclic references cannot be detected by python's garbage collector.

. Cyclic references are automatically broken by python's garbage collector

Cyclic references do not affect garbage collection.

Question 6

Which module in python provides the garbage collection functionality?

collect

garbage

memory

Question 7

How can you explicitly invoke the garbage collector in python?

Using gc.remove()

Using gc.clear()

Using gc.collect()

Using gc.release()

Question 8

Can the garbage collection mechanism in python be disabled?

Yes, but it's not recommended.

No, it's an integral part of python's memory management.

Yes, by setting a flag in the gc module.

Yes, but it requires modifying the interpreter's source code.

Question 9

When does python's garbage collection usually occur?

At a fixed time interval.

When the program is executed.

When the memory is full.

When triggered by the interpreter or explicitly requested.

Question 10

What objects are eligible for garbage collection in python?

Objects with a reference count of 1 or more.

Objects with a reference count of 0.

Objects with a reference count greater than 1.

Objects with a reference count less than 0.
