Convert tuple

The tuple data structure is used to store a group of data. The elements in this group are separated by a comma. Once created, the values of a tuple cannot change.

An example of a tuple would be:

personInfo = ("Diana", 32, "New York")

Convert list to a tuple

To convert a list to a tuple you can use the tuple() function.

#!/usr/bin/env python
listNumbers = [6,3,7,4]
x = tuple(listNumbers)

Convert tuple to list

You can convert an existing tuple to a list using the list() function:

#!/usr/bin/env python
x = (4,5)       
listNumbers = list(x)  

Convert tuple to string

If your tuple contains only strings (text) you can use:

#!/usr/bin/env python
person = ('Diana','Canada','CompSci')
s = ' '.join(person) 

Sort a tuple

Tuples are arrays you cannot modify and don’t have any sort function.

But, there is a way. You can however use the sorted() function which returns a list. This list can be converted to a new tuple.

#!/usr/bin/env python
person = ('Alison','Victoria','Brenda','Rachel','Trevor')
person = tuple(sorted(person))

Keep in mind a tuple cannot be modified, we simple create a new tuple that happens to be sorted.
