You can sort the tuple by using the built-in function sorted() or sort() in Python. sorted() returns the sorted sequence. If you want to sort a list in place then use list.sort().
Examples of sorting tuple in Python
let’s see the example of using multiple methods to sort a tuple in python.
Use of sorted() method
The sorted () function will sort a tuple and returns a tuple with the elements in a sorted manner, without modifying the original sequence ( Will create a new tuple). See below example of it:-
tup = [('lucky', '18.265'), ('nikhil', '14.107'), ('akash', '24.541'),
('anand', '4.256'), ('gaurav', '10.365')]
print(sorted(tup))
Output:
[(‘akash’, ‘24.541’), (‘anand’, ‘4.256’), (‘gaurav’, ‘10.365’), (‘lucky’, ‘18.265’), (‘nikhil’, ‘14.107’)]
In-place way of sorting using sort():
While sorting a tuple element order via sort() function the actual content of the tuple is changed, while in the sorted() function the content of the original tuple remained the same.
tup = [('lucky', '18.265'), ('nikhil', '14.107'), ('akash', '24.541'),
('anand', '4.256'), ('gaurav', '10.365')]
# Sorting a tuple
tup.sort()
print(tup)
Output:
[(‘akash’, ‘24.541’), (‘anand’, ‘4.256’), (‘gaurav’, ‘10.365’), (‘lucky’, ‘18.265’), (‘nikhil’, ‘14.107’)]
Q: How to Sort Tuples in Increasing Order by any key?
Answer: You need to sort them according to any given key. So you have to use the sorted() function where we sort them using key=last and store last as the key index according to which we have to sort the given tuples.
Input: A = [(2, 55), (1, 20), (4, 40), (2, 30)]
k = 0
Output: [(1, 20), (2, 30), (2, 55), (4, 40)]Example of Increasing Sorted order using the 0th index key.
def data(n):
return n[k]
def tuplesort(tup):
return sorted(tup, key=data)
# Driver code
a = [(230, 456, 120), (205, 414, 39), (89, 410, 213)]
k = int(input("Enter the Index ::>"))
print("Sorted:"),
print(tuplesort(a))Output:
