Write steps to create a package. Apply these steps to create a package named volume and create 3 modules in it named cube, cuboid and sphere, having function to calculate volume of the cube, cuboid and sphere respectively. Import the modules defined in the package and use the defined functions for calculation of volume respectively

Steps to Create a Package in Python

1. Create a Directory for the Package: The directory name will be the package name.
2. Add an __init__.py File: This file is required to make Python treat the directory as a package. It can be empty or contain initialization code for the package.
3. Create Modules: Add Python files (modules) inside the package directory. Each file will contain functions or classes related to a specific functionality.

Example: Create a Package Named volume

1. Step 1: Create Directory:

• Create a directory named volume.

1. Step 2: Add __init__.py File:

• Inside the volume directory, create an empty __init__.py file.

1. Step 3: Create Modules:

• Inside the volume directory, create three modules: cube.py, cuboid.py, and sphere.py.

Implement the Modules

1. cube.py:

   def volume_of_cube(side_length):
       return side_length ** 3

2. cuboid.py:

   def volume_of_cuboid(length, width, height):
       return length * width * height

3. sphere.py:

   import math

   def volume_of_sphere(radius):
       return (4/3) * math.pi * (radius ** 3)

Directory Structure

Your directory structure should look like this:

volume/
    __init__.py
    cube.py
    cuboid.py
    sphere.py

Using the Package

Create a new Python script in the same directory as the volume package to import and use the functions from the package.

Example Script to Use the Package

# Import the modules from the volume package
from volume import cube, cuboid, sphere

# Calculate volume of a cube
side_length = 3
cube_volume = cube.volume_of_cube(side_length)
print(f"Volume of the cube with side length {side_length}: {cube_volume}")

# Calculate volume of a cuboid
length = 5
width = 3
height = 2
cuboid_volume = cuboid.volume_of_cuboid(length, width, height)
print(f"Volume of the cuboid with length {length}, width {width}, height {height}: {cuboid_volume}")

# Calculate volume of a sphere
radius = 4
sphere_volume = sphere.volume_of_sphere(radius)
print(f"Volume of the sphere with radius {radius}: {sphere_volume}")

Explanation

1. Import the Modules:

• The from volume import cube, cuboid, sphere statement imports the specific modules from the volume package.

1. Use the Functions:

• The volume_of_cube function is called with side_length as an argument, and its result is printed.
• The volume_of_cuboid function is called with length, width, and height as arguments, and its result is printed.
• The volume_of_sphere function is called with radius as an argument, and its result is printed.

Using these steps, you can create a package in Python and define multiple modules in it to organize and reuse your code effectively.
