Question

Use Python to write the following code.

Program Specifications:

You are to 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

D] Display all numbers entered

Q] Quit

If the user enters G, S, A, H, L, or D before selecting G the program needs to advise the user to go and enter a number first.

Rules for the Programmer (you)

1. Source code must use a dynamic list to store all numbers
2. Source code must have a function for each of the menu options above (I guess even for quit too]
3. Source code must have reasonable comments
4. Source code must not allow the user to do bad things (you can assume they will enter a number if they press G or if you want to figure it out, yell at the user if he or she does not enter a number)

Answer 1

Code:

input_list=[] #declare input list

def get_number(): #get_number() function which takes input and append to list

val=int(input("\nEnter an element: "))
  
input_list.append(val)
  
main() #calling main() after taking input

def display_sum(): #function to display sum

if len(input_list)>0: #if input contains elements then display sum
  
print("\nCurrent sum is {}".format(sum(input_list)))

else:
  
print("\nNo numbers in list.")

main() #calling main() for displaying menu

def display_avg(): #function display average

if len(input_list)>0:
  
print("\nCurrent average is {}".format(sum(input_list)/len(input_list))) #printing average by finding sum / length of list

else:
  
print("\nNo numbers in list.")

main()

def display_max(): #function to display max

if len(input_list)>0:
  
print("\nCurrent highest number is {}".format(max(input_list)))

else:
  
print("\nNo numbers in list.")

main()
  
  
def display_min(): #function to display minimum of input list

if len(input_list)>0:
  
print("\nCurrent lowest number is {}".format(min(input_list))) #printing min value

else:
  
print("\nNo numbers in list.")

main() #calling main() function
  
def display_all(): #display all values in list function

if len(input_list)>0:
  
print("\nAll numbers are {}".format(input_list)) #if list contains elements display values

else:
  
print("\nNo numbers in list.")

main()
  
def quit_program(): #function to quit the program
  
return
  
def main():

print("\nG] Get a number\nS] Display current sum\nA] Display current average")
print("H] Display the current highest number\nL] Display the current lowest number")
print("D] Display all numbers entered\nQ] Quit") #print menu
  
option=input("Enter an option: ") #take option from user
  
if option=='G': #based on option call the appropriate function
  
get_number()

elif option=='S':
  
display_sum()

elif option=='A':
  
display_avg()

elif option=='H':
  
display_max()

elif option=='L':
  
display_min()
  
elif option=='D':
  
display_all()

elif option=='Q':
  
quit_program()

else:
  
print("Invalid option. Select valid option") #any option out of menu print invalid option
  
main()
  
main()
