Python | Min and Max value in list of tuples
• Last Updated : 07 Feb, 2019

The computation of min and max value is a quite common utility in any programming domain be it development or any other field that includes any programming constructs. Sometimes, data can come in the format of tuples and min and max operations have to be performed in them. Let’s discuss certain ways in which this is handled.

Method #1 : Using `min()` and `max()`
In this method, we use the python inbuilt `min `and `max `functions to perform the task of getting the minimum and maximum value of a particular element position.

 `# Python3 code to demonstrate ``# min and max in list of tuples``# using min() and max()`` ` `# initializing list  ``test_list ``=` `[(``2``, ``3``), (``4``, ``7``), (``8``, ``11``), (``3``, ``6``)]`` ` `# printing original list``print` `(``"The original list is : "` `+` `str``(test_list))`` ` `# using min() and max()``# to get min and max in list of tuples``res1 ``=` `min``(test_list)[``0``], ``max``(test_list)[``0``]``res2 ``=` `min``(test_list)[``1``], ``max``(test_list)[``1``]`` ` `# printing result ``print` `(``"The min and max of index 1 :  "` `+`  `str``(res1))``print` `(``"The min and max of index 2 :  "` `+`  `str``(res2))`
Output:
```The original list is : [(2, 3), (4, 7), (8, 11), (3, 6)]
The min and max of index 1 :  (2, 8)
The min and max of index 2 :  (3, 11)
```

Method #2 : Using `map() + zip()`
This is the more elegant way to perform this particular task. In this task we use `map` function to link the elements to the `zip `functions that accumulates to perform the functionality of min function or max function.

 `# Python3 code to demonstrate ``# min and max in list of tuples``# using map() + zip()`` ` `# initializing list  ``test_list ``=` `[(``2``, ``3``), (``4``, ``7``), (``8``, ``11``), (``3``, ``6``)]`` ` `# printing original list``print` `(``"The original list is : "` `+` `str``(test_list))`` ` `# using map() + zip()``# to get min and max in list of tuples``res1 ``=` `list``(``map``(``max``, ``zip``(``*``test_list)))``res2 ``=` `list``(``map``(``min``, ``zip``(``*``test_list)))`` ` `# printing result ``print` `(``"The indices wise maximum number : "` `+`  `str``(res1))``print` `(``"The indices wise minimum number : "` `+`  `str``(res2))`
Output:
```The original list is : [(2, 3), (4, 7), (8, 11), (3, 6)]
The indices wise maximum number : [8, 11]
The indices wise minimum number : [2, 3]
```
