Question in Python code: Use dictionary/data structure to return more than one value from a function. So my code is fully operational, I just need help in the portion where I need to return my results of the four operations in a dictionary AllInOne(num1,num2).

Sample output

res=AllInOne(5,2)

The results will be return in this format;

res is dictionary {"add":7, "sub":3, "mult":10, "div":2.5)

from res, you are going to print

5 + 2 = 7

5 - 2 = 3

5 * 2 = 10

5 / 2 = 2.5

res is dictionary {"add":7, "sub":3, "mult":10, "div":2.5)

NOTE:

The only thing I need in my main code is to condense this as a dictionary/data return structure and eliminate all of the print() lines.

elif choice == int('5'): #HELP_HERE_PLEASE#res = AllInOne(num1,num2) print(num1,"+",num2,"=", Mylib.scalc(str(num1)+','+str(num2)+',+')) print(num1,"-",num2,"=",Mylib.scalc(str(num1)+','+str(num2)+',-')) print(num1,"*",num2,"=",Mylib.scalc(str(num1)+','+str(num2)+',*')) print(num1, "/", num2, "=", round(Mylib.scalc(str(num1)+','+str(num2)+',/'), 12))
