Using the Bubble Sort

We can execute the sorting using the Bubble Sort approach. Each tuple represents an element in the supplied list. The nested loops are used to access the second element of each tuple. The in-place method of sorting is used here. The time complexity is O(n2), which is similar to the Bubble Sort.

def Sort_Tuple(tup):
	lst = len(tup)
	for i in range(0, lst):
		for j in range(0, lst-i-1):
			if (tup[j][1] > tup[j + 1][1]):
				temp = tup[j]
				tup[j]= tup[j + 1]
				tup[j + 1]= temp


	return tup

tup =[('for', 24), ('is', 10), ('Tuples', 28), ('wholeblogs', 5), ('portal', 20), ('a', 15)]
print(Sort_Tuple(tup))

Reasons to Sort A List Of Tuples In Python

There are a number of reasons you might want to sort a list of tuples in Python. For example, if you were doing data analysis and wanted to sort the tuples by the second element in each tuple (i.e., the value), this would be a way to do it.

Or if you were working with financial data and wanted to sort the tuples by the first element in each tuple (i.e., the date), this would be a way to do it. Let’s take a look at how to sort a list of tuples in Python.

The first thing we’ll need to do is import the built-in sorting function from the Python standard library.
