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

PythonProgrammingServer Side Programming

List is given, our task is to sort a list according to the second element in the sublist. Here we apply simple bubble sort.

## Example

Input : [['CCC', 15], ['AAA', 10], ['RRRR', 2],['XXXX', 150]]
Output : [['RRRR', 2], ['AAA', 10], ['CCC', 15], ['XXXX', 150]]

## Algorithm

Step 1: Given a list.
Step 2: We have tried to access the second element of the sublists using the nested loops.
Step 3: Traverse through all array elements.
Step 4: Last i elements are already in place.
Step 5: traverse the array from 0 to n-i-1.
Step 6: Swap if the element found is greater than the next element.

## Example Code

# Python program to sort the lists using the second element of sublist
# In place way to sort, use of third variable.
def sortlist(A):
l = len(A)
for i in range(0, l):
for j in range(0, l-i-1):
if (A[j] > A[j + 1]):
tempo = A[j]
A[j]= A[j + 1]
A[j + 1]= tempo
return A

# Driver Code
A = [['AAA', 10], ['CCC', 15], ['RRRR', 2], ['XXXX', 150]]
print(sortlist(A))

## Output

[['RRRR', 2], ['AAA', 10], ['CCC', 15], ['XXXX', 150]]
