# Python | Index minimum value Record

• Last Updated : 27 Dec, 2019

In python we can bind a structural information in form of tuples and then can retrieve the same and has manyfold application. But sometimes we require the information of tuple corresponding to minimum value of other tuple index. This functionality has many applications such as ranking. Lets discuss certain ways in which this can be achieved.

Method #1 : Using `min() + operator.itemgetter()`
We can get the minimum of corresponding tuple index from a list using the key itemgetter index provided and then mention the index information required using index specification at the end.

 `# Python 3 code to demonstrate ``# Index minimum value Record``# using min() + itemgetter()``from` `operator ``import` `itemgetter`` ` `# initializing list ``test_list ``=` `[(``'Rash'``, ``143``), (``'Manjeet'``, ``200``), (``'Varsha'``, ``100``)]`` ` `# printing original list ``print` `(``"Original list : "` `+` `str``(test_list))`` ` `# using min() + itemgetter()``# Index minimum value Record``res ``=` `min``(test_list, key ``=` `itemgetter(``1``))[``0``]`` ` `# printing result``print` `(``"The name with minimum score is : "` `+` `res)`
Output :

```Original list : [('Rash', 143), ('Manjeet', 200), ('Varsha', 100)]
The name with minimum score is : Varsha
```

Method #2 : Using `min()` + lambda
This method is almost similar to the method discussed above, just the difference is the specification and processing of target tuple index for minimum is done by lambda function. This improved readability of code.

Output :
```Original list : [('Rash', 143), ('Manjeet', 200), ('Varsha', 100)]
The name with minimum score is : Varsha
```
