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)]`
