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
