Function to calculate the square and cube of a number - Python Program

Example 1 :

Python 
def square_and_cube(num):
    """Return square and cube of num."""
    return num**2, num**3

sq, cb = square_and_cube(4)
print("Square:", sq, "Cube:", cb)

Output

 
OUTPUT  :
Square: 16 Cube: 64

Example 2 : Advanced Program

Python 
def calculate_square_and_cube(number):
    """
    Calculates the square and cube of a given number and prints the results.

    Args:
        number (int or float): The number for which to calculate the square and cube.
    """
    square = number ** 2
    cube = number ** 3
    print(f"The square of {number} is: {square}")
    print(f"The cube of {number} is: {cube}")

# Example Usage:
# Get input from the user
try:
    user_input = float(input("Enter a number: "))
    calculate_square_and_cube(user_input)
except ValueError:
    print("Invalid input. Please enter a valid number.")

print("\nAnother example with a pre-defined number:")
calculate_square_and_cube(5)

Output

 
OUTPUT  :
Enter a number: 10
The square of 10.0 is: 100.0
The cube of 10.0 is: 1000.0

Another example with a pre-defined number:
The square of 5 is: 25
The cube of 5 is: 125

Explanation:

calculate_square_and_cube(number) Function:

  • This function is defined using the defkeyword and takes one argument, number, which represents the value for which the square and cube will be calculated.
  • Inside the function, number ** 2 calculates the square of the input number, and number ** 3 calculates its cube. The ** operator in Python performs exponentiation.
  • The results are stored in variables square and cube, respectively.
  • Finally, the print() statements display the original number, its calculated square, and its calculated cube in a user-friendly format using f-strings for easy formatting.
