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 listtest_list = [[5, 6, 7], [9, 10, 2], [10, 3, 4]] # printing original listprint("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 resultprint("Max value of Nth column is : " + str(res)) |
The original list is : [[5, 6, 7], [9, 10, 2], [10, 3, 4]] Max value of Nth column is : 7
