How to add in list a new parameter's so that they saving

Python Help
1

Hello, guys. I’m new to Python, and I’m currently working on a program. In this program, I need to create a function to add a new column for drivers. However, I’m not sure how to do this correctly. I attempted to use a standard list and the ‘append’ function, but it only works once. When I try to add another entry, the program doesn’t recognize what I entered previously. I hope I have explained the problem clearly, and I would appreciate your help.

Yep, you’ve explained the problem, but it would help us a lot if we could also see your code. Paste it in here, then select it and select the </> button on the toolbar, which will make it into a preformatted code block.

Okay, when I’ll back home, I’ll send you part of my code, with comments, that you can understand what I talking about.

#importing time to using sleep
import time
#my list of users, which when I need i selected
list_of_reg_num = ['Alexander Pushkin, Mikhail Lermontov, Leo Tolstoy']
#Input which allows you to enter in "adding mode"
sel_num = input("Select a driver from the list: " + str(list_of_reg_num) + "\nTo go to Add New User mode, type "Add New User" (small letter is fine). ")
time.sleep(0.5)
#function which created to help add new user in list
def add_new_user():
    if sel_num.lower() == "Add a new user":
        print("You are now in add new user mode...")
        time.sleep(1)
        back = input("To cancel this action, simply press Enter. \If you do want to add a new user, type "Add" (lowercase letters are allowed). ")
        if back == "":
            print("The program will now complete its work...")
            time.sleep(1)
            exit()
        #If user complete all of this checks, and he really want to adding a new user, program are request a first name and the last name.
        elif back.lower() == "add":
            new_value = input("Enter the first name and last name of the user you want to add: ")
            save = input("Save the result? ")
            #if users entered "yes", program are adding new value to my list_of_red_num, but this is for one time, when program are closing values doesn't save.
            if save.lower() == "да":
                list_of_reg_num.append(new_value)
                print(list_of_reg_num)
                print("The program will restart with the new data...")
                time.sleep(1)
                exit()

I hope this could help you, below you can check what is displayed in the terminal

Choose a driver from the list: ['Alexander Pushkin', 'Mikhail Lermontov', 'Leo Tolstoy']
To go to the mode of adding a new user write "Add new user" (can be with a small letter) Add new user
Now you have gone to add a new user...
To cancel this action just press "Enter". 
If you want to add a new user just type in Add.
Enter user name you wish to add: Vladislav Ivanov
Will you save the result?
['Alexander Pushkin', 'Mikhail Lermontov', 'Leo Tolstoy', 'Vladislav Ivanov']
The program will restart with the new data...

At what point does the program actually restart with the new data? Currently it just exits.

The code that I see as I’m writing this has syntax errors, and when fixed, doesn’t produce the given output.
