Calling a function from another function using a text menu

Question

I have two functions one is my main_menu that lets the user input a number to invoke another function. When the number 1 is selected I get the error "NameError: name 'createDirectory' is not defined". I just thought it would be as easy as calling the function createDirectory, but obviously not. Can anyone point me in the right direction please?

from os import makedirs, path
# import shutil


def main_menu():
    print("PLEASE CHOOSE AN OPTION BELOW BY ENTERING THE CORRESPONDING NUMBER:  \n")

    print("[1]: CREATE CASE FOLDER STRUCTURE")

    print("[2]: BACK CASE UP TO SERVER")

    print("[3]: CLOSE PROGRAMME \n")


main_menu()

while True:
    # choice = int(input("ENTER YOUR CHOICE HERE:"))
    try:
        choice = int(input("ENTER YOUR CHOICE HERE:"))
        if choice == 1:
            createDirectory(targetPath)
            main_menu()
            break

        elif choice == 2:
            # backUpCase('src', 'dst')
            main_menu()
            break

        elif choice == 3:
            break

        else:
            print("INVALID CHOICE!! PLEASE ENTER A NUMBER BETWEEN 1-3")
            main_menu()

    except ValueError:
        print("INVALID CHOICE!! PLEASE ENTER A NUMBER BETWEEN 1-3")

    exit()

main_menu()

        makedirs(targetPath)
        print('Created folder ' + targetPath)

Answer 1

You should define your createDictionary function before the while True loop. In your code when you call the createDictionary function it is still not defined.
