why doesnt the print show up
When you're taking input for the operator on line 6, you need to convert it to an integer type. (All inputs by default are of string type.)
So on line 11 you're essentially checking "1" (a string) against 1 (an integer), which won't match.
You also need to do this for num1 and num2 - the inputs received are also strings so if you enter 7 and 6 as inputs, the output will be "7" + "6" which is "76" and not 13.
example code -> num1 = int(input("Please enter your first number: "))
Also, as @ch1ck3n mentioned below, you don't need the print function inside the input function.
