elif operatipn==4:
    print("Answer= "+ int(number1/number2))
else:
    print("You didn't choose anything in list")

>Solution :

The problem here is that you are trying to add an int object to a str object in the print statements:

print("Answer= "+ int(number1-number2))

you just need to convert it to str not an int because the result of the – or + operations on int objects will be int:

print("Answer= "+ str(number1-number2))
