Python program to sort a list of tuples alphabetically

When it is required to sort a list of tuples in alphabetical order, the 'sort' method can be used. When using this, the contents of the original tuple get changed, since in-place sorting is performed.

The 'sort' function sorts the values in ascending order by default. If the order of sorting is specified as descending, it is sorted in descending order.

A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on).

A list of tuple basically contains tuples enclosed in a list.

Below is a demonstration of the same −


Live Demo

def sort_tuple_vals(my_tup):  
   my_tup.sort(key = lambda x: x[0])
   return my_tup
my_tup = [("Hey", 18), ("Jane", 33), ("Will", 56),("Nysa", 35), ("May", "Pink")]
print("The tuple is ")
print("After sorting the tuple alphabetically, it becomes : ")


The tuple is
[('Hey', 18), ('Jane', 33), ('Will', 56), ('Nysa', 35), ('May', 'Pink')]
After sorting the tuple alphabetically, it becomes :
[('Hey', 18), ('Jane', 33), ('May', 'Pink'), ('Nysa', 35), ('Will', 56)]


  • A function named 'sort_tuple_vals' is defined, that takes a tuple as a parameter.
  • It uses the sort method and the lambda function to sort the elements in the tuple.
  • This is returned when the function is called.
  • Now the tuple is defined, and the function is called by passing this tuple as the parameter.
  • The output is displayed on the console.
