# how to find the cube of a number in python with code examples

Finding the cube of a number in Python is a relatively simple task that can be accomplished with the use of the exponent operator (**). The exponent operator raises a number to a given power, and in the case of finding the cube of a number, we want to raise the number to the power of 3.

To find the cube of a number in Python, you can use the following syntax:

```number = 5
result = number ** 3
print(result)
```

In this example, the variable "number" is set to the value of 5, and the variable "result" is set to the cube of "number" by using the exponent operator (**). The result is then printed to the console using the "print()" function, which outputs the value of 125.

Another way to find the cube of a number in Python is by using the built-in "pow()" function. The "pow()" function takes two arguments: the number to be raised to a power and the power to which the number will be raised. To find the cube of a number, the second argument should be 3.

```number = 5
result = pow(number, 3)
print(result)
```

This code is equivalent to the previous example and will also output the value of 125.

You can also find the cube of a number using the math library in python.

```import math
number = 5
result = math.pow(number, 3)
print(result)
```

In this example, we first imported the math library then used the pow() function to calculate the cube of number 5.

You can also define a function to find the cube of a number, this is useful when you want to find the cube of multiple numbers in your code.

```def find_cube(num):
return num ** 3

number = 5
result = find_cube(number)
print(result)
```

In this example, we defined a function `find_cube(num)` that takes in a number as an argument, raises it to the power of 3 and returns the result. We then call this function with the number 5 and store the result in the variable `result`.

In conclusion, finding the cube of a number in Python can be done using the exponent operator (**), the built-in "pow()" function, or math library's pow() function and also with the help of function. All of these methods are simple and straightforward, and can be easily incorporated into your Python code to perform calculations on numbers.

In addition to finding the cube of a number, there are other mathematical operations that can be performed in Python. Some examples include:

• Finding the square of a number: Similar to finding the cube, the square of a number can be found using the exponent operator (**) or the "pow()" function. To find the square, the number should be raised to the power of 2.
```number = 5
result = number ** 2
print(result)

#or

result = pow(number, 2)
print(result)
```
• Finding the square root of a number: The square root of a number can be found using the "math.sqrt()" function from the math library in python.
```import math
number = 25
result = math.sqrt(number)
print(result)
```
• Rounding a number: The "round()" function can be used to round a number to a specified number of decimal places. If no decimal places are specified, the number will be rounded to the nearest whole number.
```number = 3.14159
result = round(number, 2)
print(result)
```
• Generating random numbers: The "random" module in Python provides a number of functions for generating random numbers. The "random()" function generates a random float between 0 and 1, while the "randint()" function generates a random integer within a specified range.
```import random
result = random.random()
print(result)

result = random.randint(1, 10)
print(result)
```
• Performing trigonometric calculations: The math library in Python also includes functions for performing trigonometric calculations, such as sine, cosine, and tangent. These functions take an angle in radians as an argument.
```import math
angle = math.pi / 2
result = math.sin(angle)
print(result)

result = math.cos(angle)
print(result)

result = math.tan(angle)
print(result)
```

These are some of the common mathematical operations that can be performed in Python, but the language has many more functions and libraries for handling mathematical calculations. It is a powerful tool for performing complex mathematical operations and can be used in a wide range of applications, from scientific research to financial modeling.
