'return' 外部函數 SyntaxError

Question

我剛開始學習 python（請不要評判我的代碼），並且對為什么我收到標題為“'return' external function”的語法錯誤感到困惑。 有人可以幫我嗎？ 另外，如果有任何其他錯誤，你能幫我解決嗎？ 謝謝！

這是我的代碼：

print("Hello! Welcome to Your Personal Geometric Calculator!")

choice = print("Would you Like to Calculate Area (A), Perimeter (P), or Volume (V)")

π = 3.14159

#Area

if choice == "A" or choice == "a":

    shape = input("What Shape do you Want to Find the Area of?:")

if shape == "Circle" or shape == "circle":

    rC = int(input("Enter the Radius of the Circle (Use Meters):"))
              
    print("The Area of the Circle:", π * (rC * rC), "m^2")

elif shape == "Square" or shape == "square":
                  
    sL = int(input("Enter the Length of the Side of the Square (Use Meters):"))
                  
    print("Area of the Sqaure:", sL * sL, "m^2")     

elif shape == "Rectangle" or shape == "rectangle":

    lR = int(input("Enter the Length of the Rectangle (Use Meters):"))
    
    wR = int(input("Enter the Width of the Rectangle:"))
    
    print("The Area of the Rectangle:", lR * wR, "m")

#Perimeter

elif choice == "P" or choice == "p":

    shape2 = ("What Shape do you Want to Find the Perimeter of?:")

if shape2 == "Circle" or shape2 == "circle":

    rC2 = int(input("Enter the Radius of the Circle (Use Meters):"))
              
    print("The Perimeter of the Circle:", 2 * (π * rC2), "m^2")

elif shape2 == "Square" or shape2 == "square":
                  
    sL2 = int(input("Enter the Length of the Side of the Square (Use Meters):"))
                  
    print("Perimeter of the Sqaure:", 4 * sL2, "m^2")

elif shape2 == "Rectangle" or shape2 == "rectangle":

    lR2 = int(input("Enter the Length of the Rectangle (Use Meters):"))
    
    wR2 = int(input("Enter the Width of the Rectangle:"))
    
    print("The Perimeter of the Rectangle:", 2 * (lR2 + wR2), "m")

#Volume

elif choice == "V" or choice == "v":

    shape3 = input("What Shape do you Want to Find the Volume of?:")

if shape3 == "Sphere" or shape3 == "sphere":

    rC3 = int(input("Enter the Radius of the Sphere (Use Meters):"))
              
    print("The Volume of the Sphere:", (4 * π * rC3 ** 3) / 3, "m^2")

elif shape3 == "Cube" or shape3 == "cube":
                  
    sL3 = int(input("Enter one Side Length of the Cube (Use Meters):"))

    print("The Volume of the Cube:", sL3 ** 3, "m^3")

elif shape3 == "Prism" or shape3 == "prism":

    lP = int(input("Enter the Length of the Prism (Use Meters):"))
    
    wP = int(input("Enter the Width of the Prism:"))

    hP = int(input("Enter the Height of the Prism:"))
    
    print("The Volume of the Prism:", lP * wR * hP, "m^3")

else:
    
    print("I'm sorry. We do not Support That Shape. Press Enter to try Again.")
    
    return choice

Answer 1

running = True
errors = False
while running:
    # Ask question
    
    # Answer, content, secondary-questions etc.
    
    # Code ran without problems, do not repeat
    if not errors: # invalid etc
        errors = False
        running = False # Done. No need to ask question again

如果在任何階段用戶沒有給出您喜歡的答案，您可以將錯誤設置為True 。

請注意，此代碼可以修改，並且您回答問題的位置可以更改。 此外，這有點笨拙，但在根據您的情況正確修改時會起作用。
