# Python – Convert Tuple to Tuple Pair

Sometimes, while working with Python Tuple records, we can have a problem in which we need to convert Single tuple with 3 elements to pair of dual tuple. This is quite a peculiar problem but can have problem in day-day programming and competitive programming. Let’s discuss certain ways in which this task can be performed.

Input : test_tuple = (‘A’, ‘B’, ‘C’)
Output : [(‘A’, ‘B’), (‘A’, ‘C’)]

Input : test_tuple = (‘X’, ‘Y’, ‘Z’)
Output : [(‘X’, ‘Y’), (‘X’, ‘Z’)]

Method #1 : Using `product() + next()`
The combination of above functions can be used to solve this problem. In this, we make pairs using product, the selection of pairing with next element is done using nex().

 `# Python3 code to demonstrate working of  ` `# Convert Tuple to Tuple Pair ` `# Using product() + next() ` `from` `itertools ``import` `product ` ` `  `# initializing tuple ` `test_tuple ``=` `(``'G'``, ``'F'``, ``'G'``) ` ` `  `# printing original tuple ` `print``(``"The original tuple : "` `+` `str``(test_tuple)) ` ` `  `# Convert Tuple to Tuple Pair ` `# Using product() + next() ` `test_tuple ``=` `iter``(test_tuple) ` `res ``=` `list``(product(``next``(test_tuple), test_tuple)) ` ` `  `# printing result  ` `print``(``"The paired records : "` `+` `str``(res)) `

Output :

```The original tuple : ('G', 'F', 'G')
The paired records : [('G', 'F'), ('G', 'G')]
```

Method #2 : Using `repeat() + zip() + next()`
This problem can also be solved using the combination of above functions. In this we perform the task of pairing using zip() and repetition using repeat().

 `# Python3 code to demonstrate working of  ` `# Convert Tuple to Tuple Pair ` `# Using repeat() + zip() + next() ` `from` `itertools ``import` `repeat ` ` `  `# initializing tuple ` `test_tuple ``=` `(``'G'``, ``'F'``, ``'G'``) ` ` `  `# printing original tuple ` `print``(``"The original tuple : "` `+` `str``(test_tuple)) ` ` `  `# Convert Tuple to Tuple Pair ` `# Using repeat() + zip() + next() ` `test_tuple ``=` `iter``(test_tuple) ` `res ``=` `list``(``zip``(repeat(``next``(test_tuple)), test_tuple)) ` ` `  `# printing result  ` `print``(``"The paired records : "` `+` `str``(res)) `

Output :

```The original tuple : ('G', 'F', 'G')
The paired records : [('G', 'F'), ('G', 'G')]
```
