How to find the cube of a number in Python

How to find the cube of a number in Python.

Here's a step-by-step tutorial on how to find the cube of a number in Python.

Step 1: Understanding the concept To find the cube of a number, you need to multiply the number by itself twice. In mathematical terms, it can be represented as n^3, where n is the number.

Step 2: Writing a function to calculate the cube In Python, you can define a function to calculate the cube of a number. Let's call this function "cube".

def cube(number):
    return number ** 3

Here, the ** operator is used to perform exponentiation. It raises the number to the power of 3, which is equivalent to finding the cube.

Step 3: Using the function to find the cube To use the cube function, you can simply pass the number you want to find the cube of as an argument.

result = cube(5)
print(result)

This will output 125, which is the cube of 5.

Step 4: Handling user input You can modify the previous code to allow the user to enter a number and calculate its cube.

number = int(input("Enter a number: "))
result = cube(number)
print("The cube of", number, "is", result)

Here, the input function is used to prompt the user to enter a number. The int function is used to convert the input to an integer, as input returns a string by default.

Step 5: Using a loop to find cubes If you want to find the cubes of multiple numbers, you can use a loop to iterate through a list of numbers.

numbers = [2, 4, 6, 8, 10]
for number in numbers:
    result = cube(number)
    print("The cube of", number, "is", result)

This will calculate and print the cubes of all the numbers in the list.

You can also use a loop to prompt the user to enter multiple numbers and calculate their cubes.

count = int(input("How many numbers do you want to cube? "))
numbers = []
for i in range(count):
    number = int(input("Enter number " + str(i+1) + ": "))
    numbers.append(number)

for number in numbers:
    result = cube(number)
    print("The cube of", number, "is", result)

In this code, the user is prompted to enter the count of numbers they want to cube. Then, a loop is used to ask the user to enter each number, which is added to the numbers list. Finally, another loop calculates and prints the cubes of all the numbers in the list.

That's it! You now have a step-by-step tutorial on finding the cube of a number in Python.
