Problem with while cicle

[Astelen]

Hi everyone,
I am a neophyte and am still studying the basics. I am following a tutorial online about how using while to create a calculator software. The teacher suggested this code:



_________

hello_mex = """Hi! I am your virtual calculator!

Here are the available functions:
- if you want to perform an addition, select 1,
- if you want to perform a subtraction, select 2,
- if you want to perform multiplication, select 3,
- if you want to perform division, select 4,
- if you want to perform an exponential calculation, select 5,
- if you want to perform a square root, select 6.
- To exit the programme you can press Esc.

while True:
    print(hello_mex)

    action = input("Enter the number corresponding to the operation to be performed: ")

    if action == "1":
        print("\n You chose: addition.\n")
        add_1 = float(input("Write the first number. "))
        add_2 = float(input("Write the second number "))
        print("The result is  " str(add_1 + add_2))

    new_action = input("\nDo you want to proceed with another function? Y?N ")
    if new_action == "Y" or new_action == "y":
        print("I am coming back to the menu'")
        continue
    else:
        print("See you!\n")
        break 

Unfortunately, everything stops when I have to insert the number related to the function to be selected and if I press number 1, it starts again with hello_mex.

Could someone please help me?? I am getting crazy!
Thanks

You are missing closing quotes for the hello_mex string, and line 21 is missing a comma. Once I fixed those, the program works as expected. I don't think you posted the code you are running.

line 21 is missing a comma.

not really

>>> print("foo" "bar")
foobar

Otherwise, you are right
