How do I use LifoQueue in Python?

LifoQueue is a thread-safe stack implementation in Python. You can use it from the queue module. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

from queue import LifoQueue

# Create a LifoQueue
stack = LifoQueue()

# Add items to the stack
stack.put(1)
stack.put(2)
stack.put(3)

# Remove items from the stack
print(stack.get())  # Outputs: 3
print(stack.get())  # Outputs: 2

What happens if I try to get an item from an empty LifoQueue?

If you try to get an item from an empty LifoQueue, it will block until an item is available. You can also use get_nowait() to raise an exception instead.
