Python: Sort a list of tuples using Lambda

Python Lambda: Exercise-3 with Solution

Write a Python program to sort a list of tuples using Lambda.

Sample Solution:

Python Code :

subject_marks = [('English', 88), ('Science', 90), ('Maths', 97), ('Social sciences', 82)]
print("Original list of tuples:")
print(subject_marks)
subject_marks.sort(key = lambda x: x[1])
print("\nSorting the List of Tuples:")
print(subject_marks)

Sample Output:

Original list of tuples:
[('English', 88), ('Science', 90), ('Maths', 97), ('Social sciences', 82)]

Sorting the List of Tuples:
[('Social sciences', 82), ('English', 88), ('Science', 90), ('Maths', 97)]
