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
