有没有一种方法可以将具有不同函数的多个if语句压缩成python中更短的内容？

Question

我目前正在创建一个计算器，向用户询问一系列问题以计算其总和的答案，但是我很快就遇到了这样一个事实：我使用了多个if语句，这使得我的代码非常困难，厌倦阅读。

我想知道是否有另一种方法来使用多个if语句，每个语句都有不同的函数，占用的空间更少，完成相同的任务。

以下是我的代码示例：

def decision():
    choice = input("""
Please Select an Option:

Type 1 for Addition, Subtraction, Multiplication and Division.
Type 2 for Squares or Square Roots, Cubes or Cube Roots, Powers, Roots and Percentages.
Type 3 for Greater Than and Less Than.
Type 4 for H.C.F(Highest Common Factor), G.C.D(Greatest Common Divisor) and L.C.M(Least Common Multiple).
Type 5 for Converting Degrees to Radians.

Type 6 for Calculating Grades from Marks.
Type 7 for Perimeter, Circumference, Area, Surface Area and Volume of Shapes.

Selection: """)

    if choice == '1':
        ASMD()

    elif choice == '2':
        SCERP()

    elif choice == '3':
        GL()

    elif choice == '4':
        HCF_GCD_LCM()

    elif choice == '5':
        DR()

    elif choice == '6':
        CG()

    elif choice == '7':
        PCASAV()

    else:
        print("You have not selected a Valid Option. Please run the program again.")

        input("Press Enter to continue...")
        exit()
