Python | tuple() Function
The tuple() function is a built-in function in Python that can be used to create a tuple.
A tuple is an immutable sequence type.
Syntax:
tuple(iterable)
Parameters: This function accepts a single parameter iterable (optional). It is an iterable(list, range etc..) or an iterator object. If an iterable is passed, the corresponding tuple is created. If the iterable is not passed, empty tuple is created .
Returns: It does not returns any-thing but creates a tuple.
Error and Exception: It returns a TypeError, if an iterable is not passed.
Below programs illustrate tuple() function in Python:
Program 1: Program demonstrating the use of tuple() function
# Python3 program demonstrating # the use of tuple() function # when parameter is not passed tuple1 = tuple() print(tuple1) # when an iterable(e.g., list) is passed list1= [ 1, 2, 3, 4 ] tuple2 = tuple(list1) print(tuple2) # when an iterable(e.g., dictionary) is passed dict = { 1 : 'one', 2 : 'two' } tuple3 = tuple(dict) print(tuple3) # when an iterable(e.g., string) is passed string = "geeksforgeeks" tuple4 = tuple(string) print(tuple4) |

(1, 2, 3, 4)
(1, 2)
('g', 'e', 'e', 'k', 's', 'f', 'o', 'r', 'g', 'e', 'e', 'k', 's')
Program 2: Program demonstrating the TypeError
# Python3 program demonstrating # the TypeError in tuple() function # Error when a non-iterable is passed tuple1 = tuple(1) print(tuple1) |
