# Python | Index Maximum among Tuples

Sometimes, while working with records, we might have a common problem of maximizing contents of one tuple with corresponding index of other tuple. This has application in almost all the domains in which we work with tuple records. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using `map() + lambda + max()`
Combination of above functionalities can solve the problem for us. In this, we compute the maximum using lambda functions and max() and extend the logic to keys using map().

 `# Python3 code to demonstrate working of ` `# Index Maximum among Tuples ` `# using map() + lambda + max() ` ` `  `# initialize tuples  ` `test_tup1 ``=` `(``10``, ``4``, ``5``) ` `test_tup2 ``=` `(``2``, ``5``, ``18``) ` ` `  `# printing original tuples  ` `print``(``"The original tuple 1 : "` `+` `str``(test_tup1)) ` `print``(``"The original tuple 2 : "` `+` `str``(test_tup2)) ` ` `  `# Index Maximum among Tuples ` `# using map() + lambda + max() ` `res ``=` `tuple``(``map``(``lambda` `i, j: ``max``(i, j), test_tup1, test_tup2)) ` ` `  `# printing result ` `print``(``"Resultant tuple after maximization : "` `+` `str``(res)) `

Output :

```The original tuple 1 : (10, 4, 5)
The original tuple 2 : (2, 5, 18)
Resultant tuple after maximization : (10, 5, 18)
```

Method #2 : Using `map() + zip() + max()`
The combination of above functions can also be used to achieve this particular task. In this, we add inbuilt max() to perform maximization and zip the like indices using zip() and extend logic to both tuples using map().

 `# Python3 code to demonstrate working of ` `# Index Maximum among Tuples ` `# using map() + zip() + max() ` ` `  `# initialize tuples  ` `test_tup1 ``=` `(``10``, ``4``, ``5``) ` `test_tup2 ``=` `(``2``, ``5``, ``18``) ` ` `  `# printing original tuples  ` `print``(``"The original tuple 1 : "` `+` `str``(test_tup1)) ` `print``(``"The original tuple 2 : "` `+` `str``(test_tup2)) ` ` `  `# Index Maximum among Tuples ` `# using map() + zip() + max() ` `res ``=` `tuple``(``map``(``max``, ``zip``(test_tup1, test_tup2))) ` ` `  `# printing result ` `print``(``"Resultant tuple after maximization : "` `+` `str``(res)) `

Output :

```The original tuple 1 : (10, 4, 5)
The original tuple 2 : (2, 5, 18)
Resultant tuple after maximization : (10, 5, 18)
```
