Python | Find maximum value in each sublist

Given a list of lists in Python, write a Python program to find the maximum value of the list for each sub-list. 

Examples:

Input : [[10, 13, 454, 66, 44], [10, 8, 7, 23]]
Output :  [454, 23]

Input : [[15, 12, 27, 1, 33], [101, 58, 77, 23]]
Output :  [33, 101]

Get maximum value in each sublist using loop

Here, we are selecting each list using a Python loop and find a max element in it, and then appending it to our new Python list.

Python3

# Initialising List
a = [[10, 13, 454, 66, 44], [10, 8, 7, 23]]
lis = []

# find max in list
for p in a:
    lis.append(max(p))

# Printing max
print(lis)

Output:

[454, 23]

Get maximum value in each sublist using list comprehension

Here, we are selecting each list using a Python list comprehension and finding a max element in it, and then storing it in a Python list.

Python3

# Initialising List
a = [[10, 13, 454, 66, 44], [10, 8, 7, 23]]

# find max in list
b = [max(p) for p in a]

# Printing max
print(b)

Output:

[454, 23]

Get maximum number in each sublist using a map 

Here we are using a map method to get the maximum element from each list using a Python map.

Python3

# Initialising List
a = [[10, 13, 454, 66, 44], [10, 8, 7, 23]]

# find max in list
ans = list(map(max, a))

# Printing max
print(ans)

Output:

[454, 23]
