Python - tuple() Function

The tuple() function (or tuple() constructor) is used to create tuple using an iterable object. An iterable object can be any data structure like list, tuple, set, string and dictionary etc. An iterable created by range() function can also be used here.

Syntax

tuple(iterable)

Parameters

Return Value

Returns a tuple containing all elements of passed iterable.

Example:

In the below example, tuple() function is used to create tuple using a given iterable.

#using list as iterable
MyTuple = tuple(['JAN', 'FEB', 'MAR', 'APR'])
print(MyTuple)

#using tuple as iterable
MyTuple = tuple(('JAN', 'FEB', 'MAR', 'APR'))
print(MyTuple)

#using set as iterable
MyTuple = tuple({'JAN', 'FEB', 'MAR', 'APR'})
print(MyTuple)

#using string as iterable
MyTuple = tuple('string')
print(MyTuple)

The output of the above code will be:

('JAN', 'FEB', 'MAR', 'APR')

('JAN', 'FEB', 'MAR', 'APR')

('JAN', 'FEB', 'MAR', 'APR')

('s', 't', 'r', 'i', 'n', 'g')

Example: Using dictionary as an iterable

In the below example, tuple() function is used to create tuple from a given dictionary.

MyDict = {
  'name': 'John',
  'age': 25,
  'city': 'London'
}
MyTuple = tuple(MyDict)
print(MyTuple)

MyTuple = tuple(MyDict.keys())
print(MyTuple)

MyTuple = tuple(MyDict.values())
print(MyTuple)

The output of the above code will be:

('name', 'age', 'city')

('name', 'age', 'city')

('London', 25, 'John')
