To cube a number in Python, you can use the exponentiation operator `**`

. To calculate the cube of a number, you simply raise it to the power of 3.

Here’s an **TL;DR** example:

```
def cube_number(num):
return num ** 3
number = 5
result = cube_number(number)
print(f"The cube of {number} is {result}")
```

In this example, the `cube_number`

function takes a number as input and returns its cube using the `**`

operator. The input number 5 is passed to the function, and the resulting cube (125) is printed.

**Understanding the Concept of Cubing**

Cubing a number is a mathematical operation where a number is multiplied by itself twice. It can be expressed as `n^3`

or `n * n * n`

, where `n`

is the number being cubed.

**Methods for Cubing a Number in Python**

There are several ways to cube a number in Python, including using arithmetic operators, built-in functions, and custom functions. In this section, we will discuss five different methods.

**1) Using Arithmetic Operators**

The most straightforward method to cube a number in Python is by using the exponentiation operator `**`

.

```
number = 5
cube = number ** 3
print(cube) # Output: 125
```

**2) Using the **`pow()`

Function

`pow()`

FunctionAnother way to cube a number in Python is by using the built-in `pow()`

function. The `pow()`

function takes two arguments, the base and the exponent, and returns the result of the base raised to the power of the exponent.

```
number = 5
cube = pow(number, 3)
print(cube) # Output: 125
```

**3) Using the **`math.pow()`

Function

`math.pow()`

FunctionThe `math`

library in Python provides a `pow()`

function as well, which operates similarly to the built-in `pow()`

function. However, the `math.pow()`

function returns a float value.

```
import math
number = 5
cube = math.pow(number, 3)
print(cube) # Output: 125.0
```

**4) Using Lambda Functions**

Lambda functions are anonymous functions in Python that can be defined using the `lambda`

keyword. You can use a lambda function to create a one-line function for cubing a number.

```
cube = lambda number: number ** 3
print(cube(5)) # Output: 125
```

**5) Using List Comprehensions**

List comprehensions provide a concise way to create lists in Python. You can use them to generate a list of cubed numbers for a given range.

```
cubed_numbers = [number ** 3 for number in range(1, 6)]
print(cubed_numbers) # Output: [1, 8, 27, 64, 125]
```

**Choosing the Right Method**

The best method to cube a number in Python depends on your specific use case and requirements. If you need to cube a single number, using arithmetic operators or the built-in `pow()`

function is recommended.
