There are lots of ways to do this. The simplest is simply to
display a menu and ask the user to select an entry.
print('''
1 New
2 Edit
3 Delete
4 quit
''')
cmd = int(input('Enter an option number')
if cmd == 1:....
elif cmd == 2:....
etc
If the above explanation is still too complicated
then please come back with more questions
You can add loops and error traps if you wish.
You can put the menu inside a function. But I don't
know how much of that extra stuff you understand yet.
Another, more advanced/professional, option, which builds
applications that look like Python's help() function, is
to use the cmd module. There are examples in the documentation
Finally, if you are on *nix or MacOS you can use curses
to build a pseudo-GUI that works in a terminal. But
that is almost certainly too much for you at this stage.
