tuple() function creates and returns a new tuple object. When used without an argument, it returns an empty tuple. When used with the optional
iterable argument, it initializes the new tuple with the elements in the iterable.
Read more about tuples in our full tutorial about Python Tuples.
Learn by example! Here are some examples of how to use the
tuple() built-in function:
You can create an empty tuple by skipping the argument:
>>> tuple() ()
>>> tuple((1, 2, 3)) (1, 2, 3)
Note that it really creates a new tuple object that may be different from the one passed as an argument. However, this is not always the case:
>>> x = (1, 2, 3) >>> y = tuple(x) >>> x is y True >>> x == y True
The new tuple
y has the same elements as the original tuple
x. But as tuples are immutable—they cannot be changes—they both point to the same object in memory: as you can see from the check
x is y that returns
You can use the
tuple() method with or without the optional
Syntax: There are two ways of using the constructor:
tuple() -> new empty tuple, you'll probably never need that tuple(
iterable) -> new tuple initialized with elements in iterable

But before we move on, I’m excited to present you my brand-new Python book Python One-Liners (Amazon Link).
If you like one-liners, you’ll LOVE the book. It’ll teach you everything there is to know about a single line of Python code. But it’s also an introduction to computer science, data science, machine learning, and algorithms. The universe in a single line of Python!
The book was released in 2020 with the world-class programming book publisher NoStarch Press (San Francisco).
