Python program to sort a list according to the second element in the sublist.

ProgrammingPythonServer Side Programming

In this article, we will sort a list according to the second element in the sublist. Let’s say we have the following list −

[['jack', 50], ['antony', 20], ['jones', 87], ['gary', 70], ['tom', 90], ['sam', 110], ['warner', 65]]

The output should be the following i.e. sorted according to the second element −

[['antony', 20], ['jack', 50], ['warner', 65], ['gary', 70], ['jones', 87], ['tom', 90], ['sam', 110]]

Python program to sort a list according to the second element in the sublist using the sort() method

Example

# Custom Function def SortFunc(sub_li): sub_li.sort(key = lambda x: x[1]) return sub_li # Driver Code subList =[['jack', 50], ['antony', 20], ['jones', 87], ['gary', 70], ['tom', 90], ['sam', 110], ['warner', 65]] print("Unsorted List =
"
,subList) print("
Sorted List according to the second elemnt in the sublist =
"
,SortFunc(subList))

Output

Unsorted List = 
[['jack', 50], ['antony', 20], ['jones', 87], ['gary', 70], ['tom', 90], ['sam', 110], ['warner', 65]]

Sorted List according to the second elemnt in the sublist =
  [['antony', 20], ['jack', 50], ['warner', 65], ['gary', 70], ['jones', 87], ['tom', 90], ['sam', 110]]

Python program to sort a list according to the second element in the sublist using Bubble Sort

Example

# Custom Function def SortFunc(subList): l = len(subList) for i in range(0, l): for j in range(0, l-i-1): if (subList[j][1] > subList[j + 1][1]): temp = subList[j] subList[j]= subList[j + 1] subList[j + 1]= temp return subList # Driver Code subList =[['jack', 50], ['antony', 20], ['jones', 87], ['gary', 70], ['tom', 90], ['sam', 110], ['warner', 65]] print("Unsorted List =
"
,subList) print("
Sorted List according to the second elemnt in the sublist =
"
,SortFunc(subList))

Output

Unsorted List = 
 [['jack', 50], ['antony', 20], ['jones', 87], ['gary', 70], ['tom', 90], ['sam', 110], ['warner', 65]]

Sorted List according to the second elemnt in the sublist =
 [['antony', 20], ['jack', 50], ['warner', 65], ['gary', 70], ['jones', 87], ['tom', 90], ['sam', 110]]

Python program to sort a list according to the second element in the sublist using the sorted() method

Example

# Custom Function def SortFunc(subList): return(sorted(subList, key = lambda a: a[1])) # Driver Code subList =[['jack', 50], ['antony', 20], ['jones', 87], ['gary', 70], ['tom', 90], ['sam', 110], ['warner', 65]] print("Unsorted List =
"
,subList) print("
Sorted List according to the second elemnt in the sublist =
"
,SortFunc(subList))

Output

Unsorted List = 
 [['jack', 50], ['antony', 20], ['jones', 87], ['gary', 70], ['tom', 90], ['sam', 110], ['warner', 65]]
Sorted List according to the second elemnt in the sublist =
  [['antony', 20], ['jack', 50], ['warner', 65], ['gary', 70], ['jones', 87], ['tom', 90], ['sam', 110]]
