Question

尝试将此代码添加到我的Python程序的末尾，以询问用户是要重新启动该程序还是结束该程序。如果我说“是”，程序将再次循环，但不会询问用户是否要在结束后重新启动。我想念什么？

    while Cont != "n" and Cont != "y":
        Cont=input("Do you want to draw another shape? (y/n): ")

        #Summary
        if Cont == "n":
            print("\n")
            print("Here is a summary of the shapes drawn:\n1)Horizontal Line",Horizontal_Line,"\n2)Vertical Line",Vertical_Line,"\n3)Rectangle",Rectangle,"\n4)Right Triangle",Right_Triangle,"\n5)Isosceles Triangle",Isosceles_Triangle,"\n6)???",Trapezoid,) 
            break

Answer 1

您的while循环评估是错误的。 Cont变量将永远不会同时存储y和n，这就是为什么程序永远不会到达循环的原因。

您可以先询问，然后根据该决定进行评估。

while True:
    cont=input("Do you want to draw another shape? (y/n): ")       

    if Cont == "n":
        print("\n")
        print("Here is a summary of the shapes drawn:\n1)Horizontal Line",Horizontal_Line,"\n2)Vertical Line",Vertical_Line,"\n3)Rectangle",Rectangle,"\n4)Right Triangle",Right_Triangle,"\n5)Isosceles Triangle",Isosceles_Triangle,"\n6)???",Trapezoid,) 
        break

在这个while循环中我在做什么错
