In this article, we will discuss how to create a List of Tuples using for loop in Python.

Let’s suppose we have a list and we want a create a list of tuples from that list where every element of the tuple will contain the list element and its corresponding index.

Method 1: Using For loop with append() method

Here we will use the for loop along with the append() method. We will iterate through elements of the list and will add a tuple to the resulting list using the append() method.

L = [5, 4, 2, 5, 6, 1]
res = []

for i in range(len(L)):
	res.append((L[i], i))
	
print("List of Tuples")
print(res)

Output

List of Tuples
[(5, 0), (4, 1), (2, 2), (5, 3), (6, 4), (1, 5)]

List of Tuples [(5, 0), (4, 1), (2, 2), (5, 3), (6, 4), (1, 5)]

Method 2: Using For loop with enumerate() method

Enumerate() method adds a counter to an iterable and returns it in a form of enumerating object. So we can use this function to create the desired list of tuples.

Example:

L = [5, 4, 2, 5, 6, 1]
res = []

for index, element in enumerate(L):
	res.append((element, index))
	
print("List of Tuples")
print(res)

Output

List of Tuples
[(5, 0), (4, 1), (2, 2), (5, 3), (6, 4), (1, 5)]
