# Python | Max/Min value in Nth Column in Matrix

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
```
