Given a list of numbers of list, write a Python program to create a list of tuples having first element as the number and second element as the cube of the number. Example:

Input: list = [1, 2, 3]
Output: [(1, 1), (2, 8), (3, 27)]

Input: list = [9, 5, 6]
Output: [(9, 729), (5, 125), (6, 216)]

Method #1 : Using pow() function.We can use list comprehension to create a list of tuples. The first element will be simply an element and second element will be cube of that number. Below is the Python implementation: 

Python3




# Python program to create a list of tuples
# from given list having number and
# its cube in each tuple
 
# creating a list
list1 = [1, 2, 5, 6]
 
# using list comprehension to iterate each
# values in list and create a tuple as specified
res = [(val, pow(val, 3)) for val in list1]
 
# print the result
print(res)

Output:

[(1, 1), (2, 8), (5, 125), (6, 216)]

Method #2: Using ** operator 

Python3




# Python program to create a list of tuples
# from given list having number and
# its cube in each tuple
 
# creating a list
list1 = [1, 2, 5, 6]
 
# using list comprehension to iterate each
# values in list and create a tuple as specified
res = [(val, val**3) for val in list1]
 
# print the result
print(res)

Output

[(1, 1), (2, 8), (5, 125), (6, 216)]
