Hello I have been playing around with a menu function, which requires to write in Python a program with the following specification.

Design the following menu:

G] Get a number

S] Display current sum

A] Display current average

H] Display the current highest number

L] Display the current lowest number

Q] Quit

If the user enters G, S, A H or L before selectin Q the program needs to advise the user to go and enter a number first, in other words needs to include error checking Sources could should be written in such a way that it will work regardless of the value entered of the variable. I started from the image below I need some help.

def main(): print("G Get a Number") print ("S Display current sum") print ("A Display current Average") print("H Display teh current hight number") print("I Display the current lowest number") print("Q to Quit") selection=int (input ("Enter your choice:")) if selection==G: Number() elif selection==Sum sum() Main()
