Is there a way to, using the modules cmd or readline, get smart completion when reading an input string that only matches a specific set of values?
For instance:
read_from_list(prompt"Name:", allowed_values=["Adam", "Bert", "Cesar"])
will create prompt
Name:
If I enter
Ad
and press complete (typically via Tab-key) I get
Adam
As a bonus it shouldn't even be possible to enter a string other than Adam, Bert or Cesar together with a set of all their prefixes.
Update: In essence I want a Python 3 variant of Emacs's completing-read: https://www.gnu.org/software/emacs/manual/html_node/elisp/Minibuffer-Completion.html
