Sort list of tuples by specific ordering in Python
When it is required to sort the list of tuples in a specific order, the 'sorted' method can be used.
The 'sorted' method is used to sort the elements of a list.
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 for the same −
Example
def tuple_sort(my_tup):
return(sorted(my_tup, key = lambda x: x[1]))
my_tuple = [('Mahe', 11), ('Aisha', 33), ('Will', 50), ('Root', 65)]
print("The list of tuple is : ")
print(my_tuple)
print("The tuple after placing in a specific order is : ")
print(tuple_sort(my_tuple))Output
The list of tuple is :
[('Mahe', 11), ('Aisha', 33), ('Will', 50), ('Root', 65)]
The tuple after placing in a specific order is :
[('Mahe', 11), ('Aisha', 33), ('Will', 50), ('Root', 65)]Explanation
- A method named 'tuple_sort' is defined that takes a list of tuple as parameter.
- It uses the 'sorted' method to sort the list of tuple in the order based on the first element in every tuple inside the list of tuple.
- A list of tuple is defined, and is displayed on the console.
- The function is called by passing this list of tuple as parameter.
- This operation's data is stored in a variable.
- This variable is the output that is displayed on the console.
