このプログラムで無効な構文エラーが発生する理由がわかりません。かなり単純だと思いますが、私はこれに非常に慣れていません。ここにすべてがあります：

# Welcome Message
print ("Hello and welcome to the Plesha EasyTube Wizard!")

materials and cost of your tubes.")
print ("All measurements should be in centimeters!")
print ()

# Collect user inputs
height = float(input("Let's begin: What is the height of you desired tube? "))
radius = float(input("And what is the radius? "))
count = int(input("How many would you like? "))

# Set Constants
steelPrice = 0.14
rubberPrice = 0.02

singleTubeVol = math.pi * (radius ** 2) * height
allTubeVol = singleTubeVol * count
singleTubeSurface = (2 * math.pi * (radius ** 2)) + (2 * math.pi * radius * height)

いくつかのコンマを忘れました:

print ("You wanted ", count, " tubes in the dimesions ", height,

出力例:

Hello and welcome to the Plesha EasyTube Wizard!
Today we will be gathering measurements from you to determine the materials and cost of your tubes.
All measurements should be in centimeters!

Let's begin: What is the height of you desired tube? 10
And what is the radius? 2.5
How many would you like? 3
You wanted 3 tubes in the dimesions 10.00 centimeters by 2.50 centimeters (radius).
The volume of a single tube of your specifications is: 196.35
The total volume of your tube order will be 589.05
You will require 589.05 square centimeters of steel. Totalling 82.47 in price.
You will require 565.49 square centimeters of rubber. Totalling 11.31 in price.
Your total cost for this order will be 93.78
