A closure is a function that remembers the variables from the scope where it was created, even after that scope has exited. This allows the function to use those variables later, even if it is called from a different context.

Example

def enjoy_cheese(name):
	def cheesy_message():
		return f"Yummy, I love {name}!"
	return cheesy_message

taste_cheese = enjoy_cheese("Roquefort")
print(taste_cheese()) # Output: Yummy, I love Roquefort!

In this example, the cheesy_message function is a closure that remembers the name variable ("Roquefort") from the enjoy_cheese function, allowing it to use that value later.
