Tools to help with text mode (i.e. non-GUI) input

I'm looking for Python packages that can help with text mode input,
i.e. for use with non-GUI programs that one runs from the command
prompt in a terminal window running a bash shell or some such.

What I'm specifically after is a way to provide a default value that
can be accepted or changed easily and also a way to provide a number
of different values to choose from.

I.e. for the default sort of input one might see:-

    Colour? red

Hitting return would return 'red' to the program but you could also
backspace over the 'red' and enter something else.  Maybe even better
would be that the 'red' disappears as soon as you hit any key other
than return.


For the select a value type of input I want something like the above
but hitting (say) arrow up and arrow down would change the value
displayed by the 'Colour?' prompt and hitting return would accept the
chosen value.  In addition I want the ability to narrow down the list
by entering one or more initial characters, so if you enter 'b' at the
Colour? prompt the list of values presented would only include colours
starting with 'b' (beige, blue, black, etc.)


Are there any packages that offer this sort of thing? I'd prefer ones
from the Debian repositories but that's not absolutely necessary.


It might also be possible/useful to use the mouse for this.
