How do you create an empty tuple in Python?

An empty tuple in Python can be created using the syntax with parentheses followed by nothing inside them, which is represented as empty_tuple = (). This method directly defines an immutable sequence that contains no elements.

The alternative option of using empty_tuple = tuple() is also correct; it employs the tuple constructor to create an empty tuple, which is another valid way to achieve the same result. However, the most straightforward and common way to define an empty tuple is by simply using parentheses with nothing inside.

It's important to note that the other options do not create a tuple. For instance, using square brackets (empty_tuple = []) defines an empty list, while braces (empty_tuple = {}) create an empty dictionary. Both lists and dictionaries are mutable types, unlike tuples, which are immutable. Understanding these differences is crucial when deciding which data structure to use in Python programming.
