#   # Using User Input and a Menu to Calculate Shape Volumes in Python

In this tutorial, we will learn how to find the volume of different shapes in Python using user input and a menu to select the shape. We will cover the following shapes:

1. Cube

2. Sphere

3. Cylinder

4. Cone

Before we begin, let's first import the necessary libraries. We will be using the `math` library to perform some calculations, so make sure to import it as well.

``````import math
``````

Next, we will create a menu for the user to select the shape they want to find the volume of. We will use a `while` loop and a `switch` statement to handle the different shape options.

``````while True:
print("1. Cube")
print("2. Sphere")
print("3. Cylinder")
print("4. Cone")
print("5. Quit")

choice = int(input())

if choice == 5:
break

if choice == 1:
# Calculate the volume of a cube
pass
elif choice == 2:
# Calculate the volume of a sphere
pass
elif choice == 3:
# Calculate the volume of a cylinder
pass
elif choice == 4:
# Calculate the volume of a cone
pass
else:
``````

Now let's define the functions to calculate the volume of each shape.

## Cube

To find the volume of a cube, we need to ask the user for the length of one side of the cube. We can then use the following formula to calculate the volume:

``````volume = side^3
``````

Here is the code to implement this in Python:

``````def find_cube_volume():
side = float(input("Enter the length of one side of the cube: "))
volume = side**3
print(f"The volume of the cube is {volume}.")
``````

## Sphere

To find the volume of a sphere, we need to ask the user for the radius of the sphere. We can then use the following formula to calculate the volume:

``````volume = (4/3) * pi * radius^3
``````

Here is the code to implement this in Python:

``````def find_sphere_volume():
volume = (4/3) * math.pi * radius**3
print(f"The volume of the sphere is {volume}.")
``````

## Cylinder

To find the volume of a cylinder, we need to ask the user for the radius of the base and the height of the cylinder. We can then use the following formula to calculate the volume:

``````volume = pi * radius^2 * height
``````

Here is the code to implement this in Python:

``````def find_cylinder_volume():
radius = float(input("Enter the radius of the base of the cylinder: "))
height = float(input("Enter the height of the cylinder: "))
volume = math.pi * radius**2 * height
print(f"The volume of the cylinder is {volume}.")
``````

## Cone

To find the volume of a cone, we need to ask the user for the radius of the base and the height of the cone. We can then use the following formula to calculate the volume:

``````volume = (1/3) * pi * radius^2 * height
``````

Here is the code to implement this in Python:

``````def find_cone_volume():
radius = float(input("Enter the radius of the base of the cone: "))
height = float(input("Enter the height of the cone: "))
volume = (1/3) * math.pi * radius**2 * height
print(f"The volume of the cone is {volume}.")
``````

Here is the complete code that includes all the functions within the `while` loop:

``````import math

def find_cube_volume():
side = float(input("Enter the length of one side of the cube: "))
volume = side**3
print(f"The volume of the cube is {volume}.")

def find_sphere_volume():
volume = (4/3) * math.pi * radius**3
print(f"The volume of the sphere is {volume}.")

def find_cylinder_volume():
radius = float(input("Enter the radius of the base of the cylinder: "))
height = float(input("Enter the height of the cylinder: "))
volume = math.pi * radius**2 * height
print(f"The volume of the cylinder is {volume}.")

def find_cone_volume():
radius = float(input("Enter the radius of the base of the cone: "))
height = float(input("Enter the height of the cone: "))
volume = (1/3) * math.pi * radius**2 * height
print(f"The volume of the cone is {volume}.")

while True:
print("1. Cube")
print("2. Sphere")
print("3. Cylinder")
print("4. Cone")
print("5. Quit")

choice = int(input())

if choice == 5:
break

if choice == 1:
find_cube_volume()
elif choice == 2:
find_sphere_volume()
elif choice == 3:
find_cylinder_volume()
elif choice == 4:
find_cone_volume()
else:
