Find maximum value in each sublist in Python

We are given a list of lists. In the inner lists or sublists we are required to find the maximum value in each.

With max and in

We design a for loop with in condition and apply the max function to get the maximum value in each of the sublist.

Example

 Live Demo

Alist = [[10, 13, 454, 66, 44], [10, 8, 7, 23]] # Given list print("The given list:\n ",Alist) # Use Max res = [max(elem) for elem in Alist] # Printing max print("Maximum values from each element in the list:\n ",res)

Output

Running the above code gives us the following result −

The given list: [[10, 13, 454, 66, 44], [10, 8, 7, 23]] Maximum values from each element in the list: [454, 23]

With map and max

We keep applying the max function using map while iterating through the sublists.

Example

 Live Demo

Alist = [[10, 13, 454, 66, 44], [10, 8, 7, 23]] # Given list print("The given list:\n ",Alist) # Use Max res =list(map(max, Alist)) # Printing max print("Maximum values from each element in the list:\n ",res)

Output

Running the above code gives us the following result −

The given list: [[10, 13, 454, 66, 44], [10, 8, 7, 23]] Maximum values from each element in the list: [454, 23]
