while loop not closing

[djwilson0495]

I'm using a code with a while loop:

def main():
    print("1) Create a new user ID") # prints this menu
    print("2) Change a password")
    print("3) Display all user ID's")
    print("4) Quit")
    print()
    choice = int(input("Please enter your selection:")) # asks user for their selection
    try_again = True
    while try_again == True:
        if choice == 1:
            tmp = get_data() # gets tmp list from get_data
            New_ID = create_ID(tmp) # gets New_ID from create_ID
            password = create_password() # gets password 
            new_record = New_ID + "," + password # creates entry string
            tmp.append(new_record) # adds string to the end of tmp
            file = open("ID+Passwords.csv","w") # opens csv file in write mode
            for row in tmp:
                file.write(new_record) # writes every row of the list to the csv file
            file.close # closes the file and saves the changes 
            choice = int(input("Please enter your selection:")) # asks user for their selection
        elif choice == 2:
            tmp = get_data()
            New_ID = create_ID(tmp)
            change_password(New_ID,tmp)
            choice = int(input("Please enter your selection:")) # asks user for their selection
        elif choice == 3:
            tmp = get_data()
            display(tmp)
            choice = int(input("Please enter your selection:")) # asks user for their selection
        elif choice == 4:
            try_again == False
        else:
            choice = int(input("Incorrect choice please select a choice from the list:"))

However when I select option 4 the loop isn't closing properly, this is what my terminal looks like:

Please enter the new ID1
Please enter the new password:numbers0123
That is a strong password
Please enter your selection:4

Rather than going to the normal non-running terminal it just has a blank line underneath. Can anyone help with this?
