For this exercise, write a program that contains an introductory docstring. This documentation should describe what the program will do $($analysis$)$ and how it will do it $($design the program in the form of a pseudocode algorithm$).$ Include suitable prompts for all inputs, and label all outputs appropriately. After you have coded a program, be sure to test it with a reasonable set of legitimate inputs.

Write a program in the file sphere.py that takes the radius of a sphere $($a floating$-$point number$)$ as input and then outputs the sphere$$s diameter, circumference, surface area, and volume.

So far I have the following code:

import math

# ask the user to enter the radius of the sphere

sphere$\_$radius $=$ float$($input$("$Please$,$ enter the radius of the sphere: $"))$

# calculate the diameter of the sphere

diameter $=2*$ sphere$\_$radius

# calculate the circumference of the sphere

circumference $=2*$ math.pi $*$ sphere$\_$radius

# calculate the surface area of the sphere

surface$\_$area $=4*$ math.pi $*$ sphere$\_$radius $**2$

# calculate the volume of the sphere

volume $=(4/3)*$ math.pi $*$ sphere$\_$radius $**3$

# display the diameter of the sphere

print$("$Diameter:$",$ diameter$)$

# display the circumference of the sphere

print$("$Circumference:$",$ circumference$)$

# display the surface area of the sphere

print$("$Surface area:", surface$\_$area$)$

# display the volume of the sphere

print$("$Volume:$",$ volume$)$

However, I am getting the following error:

Status: FAILED!

Check: $7$

Test: Outputs correct values when input is $67$

Reason: Unable to find $\text{'}[\text{'}56410\mathrm{.}43768785832\text{'}]\text{'}$ in the program's output.
