Python programming language is a high-level and object-oriented programming language. Python is an easy to learn, powerful high-level programming language. It has a simple but effective approach to object-oriented programming.

Tuples in Python is a collection of items similar to list with the difference that it is ordered and immutable.

Example:

tuple = ("python", "includehelp", 43, 54.23)

Creating a list of tuples from given list having number and its cube in each tuple

We have a list of elements and we need to create another list of elements such that each element of the new list is a tuple. And each of the tuples consists of two values one the element from the list and the second will be the cube of the value.

Example

Consider the below example with sample input and output:

Input: 
list = [4, 1, 6, 2]

Output: 
[(4, 64), (1, 1), (6, 216), (2, 8)]

We simply need to iterate over all the elements of the list and then for each element create a tuple consisting of the element and its cube and then append it to a list.

This can be done by simply loop and also to shorten the code we can use comprehension techniques. Here is a code depicting both the methods.

Program

# Creating a list
myList = [6, 2, 5 ,1, 4]

# Creating list of tuples 
tupleList = [] 
for val in myList:
    myTuple = (val, (val*val*val))
    tupleList.append(myTuple)

# print the result
print("The list of Tuples is " , str(tupleList))

Output:

The list of Tuples is  [(6, 216), (2, 8), (5, 125), (1, 1), (4, 64)]

Using comprehension

# Creating a list
myList = [6, 2, 5 ,1, 4]

# Creating list of tuples 
tupleList = [(val, (val*val*val)) for val in myList]

# print the result
print("The list of Tuples is " , str(tupleList))

Output:

The list of Tuples is  [(6, 216), (2, 8), (5, 125), (1, 1), (4, 64)]
