Python | Max/Min value in Nth Column in Matrix
• Last Updated : 30 Dec, 2020

Sometimes, while working with Python Matrix, we may have a problem in which we require to find the minimum and maximum value of a particular column. This can have a possible application in day-day programming and competitive programming. Let’s discuss certain way in which this task can be performed.

Method : Using `max()/min()` +` zip()`
This task can be solved using the combination of above functions. In this, we pass in the zip() the list, to access all columns and `max()/min()` to get maximum or minimum of columns.

 `# Python3 code to demonstrate working of``# Max value in Nth Column in Matrix``# using max() + zip()`` ` `# initialize list``test_list ``=` `[[``5``, ``6``, ``7``],``             ``[``9``, ``10``, ``2``], ``             ``[``10``, ``3``, ``4``]]`` ` `# printing original list``print``(``"The original list is : "` `+` `str``(test_list))`` ` `# initialize N ``N ``=` `2`` ` `# Max value in Nth Column in Matrix``# using max() + zip()``res ``=` `[``max``(i) ``for` `i ``in` `zip``(``*``test_list)][N] `` ` `# printing result``print``(``"Max value of Nth column is : "` `+` `str``(res))`
Output :
```The original list is : [[5, 6, 7], [9, 10, 2], [10, 3, 4]]
Max value of Nth column is : 7
```
